Looking for transfer switch manufacturers in Yueqing? This guide profiles ten local or Yueqing-linked companies that publish automatic transfer switches, PC-class or CB-class ATS, manual changeover switches or source-transfer systems. It is written for buyers comparing an ATS for a utility-to-generator supply, a generator-to-generator arrangement, a building distribution board or an industrial control panel.
“Transfer switch” covers several different products. A PC-class ATS is selected primarily for transfer and isolation duty, while a CB-class ATS uses circuit-breaker constructions and has a different relationship with fault current and upstream protection. A manual changeover switch may be a small DIN-rail device or a large panel-mounted switch. An STS is a static semiconductor transfer system, not an electromechanical ATS. Start with the switching duty, source arrangement and required fault behaviour before comparing prices.
How this list was selected: Official company, product and contact pages were reviewed on 22 October 2026. The order is a research shortlist, not a quality, price, certification, export or “best” ranking. A published product category or address does not prove that BottomRace has audited every factory or that every model carries every approval. Confirm the legal entity, production site, exact model, current certificate and test scope before ordering.

Manufacturer profiles and questions to ask
1. CHINT Electrics
Short name: CHINT
Published location: CHINT Industrial Zone, North Baixiang, Yueqing
CHINT publishes a generator dual-power control system solution that uses NH40-SZIII dual-power products for utility-to-generator and generator-to-generator arrangements. This is a system-level way to start a transfer-switch enquiry, not a claim that every NH40 variant has identical contacts, operating mechanisms or approvals. Buyers should ask CHINT to map the selected switch, controller and sensing accessories to the source arrangement, load profile and required transfer sequence. Confirm the exact product model and production site rather than treating a solution page as a complete datasheet.
Before requesting a quote: Provide a single-line diagram, the two source types, system voltage and frequency, rated current, poles, neutral arrangement and load type. State whether the transfer is automatic or manual, open or closed transition, and whether a generator exercise or remote control function is needed. Ask for the exact switch and controller models, transfer time, utilisation category, short-circuit coordination, terminal data, dimensions, IP rating and the IEC 60947-6-1 evidence for the quoted configuration.
Official sources: Generator dual-power control system solution · Low-voltage distribution products · contact page.
2. DELIXI Electric
Short name: DELIXI
Published location: Delixi High-tech Industrial Park, Liushi, Yueqing
DELIXI's official English product navigation includes a transfer-switch category alongside circuit breakers, disconnectors and distribution equipment. The site does not expose one stable English product page for every transfer-switch family to every browser, so the practical first step is to ask DELIXI to identify the exact series, catalogue and manufacturing entity behind the quotation. This entry is a route for buyers already considering the DELIXI ecosystem, not evidence that a particular ATS model is suitable for a specific source or load arrangement.
Before requesting a quote: Send the source arrangement, single-line diagram, voltage, frequency, current, poles, neutral requirement and load type. State whether the switch must be PC class, CB class, manual or another construction, and give the required transfer time and control functions. Request the exact model, catalogue page, dimensional drawing, controller, utilisation category, short-circuit coordination, certificate scope and the factory that will produce the quoted item.
Official sources: DELIXI low-voltage product navigation · DELIXI official contact page · contact page.
3. People Electrical Appliance Group Co., Ltd.
Short name: PEOPLE
Published location: No. 555 Liule Road, Liushi, Yueqing
PEOPLE publishes several distinct ATS families rather than one universal transfer switch. The RDQ1 page describes a CB-class dual-power ATS for systems up to 63 A, while the RDH5D page covers a PC-class product with electrical and mechanical interlocks and a published current range up to 3,200 A. The RDQH page presents a CB-class range from 10 A to 1,600 A, and the RDWQ2 page describes a high-current intelligent transfer switch up to 6,300 A. Those families should not be compared as interchangeable products. Start with the required ATS class, breaking duty and source arrangement.
Before requesting a quote: Provide the single-line diagram, normal and backup source, system voltage and frequency, load current, poles, neutral arrangement and required ATS class. State whether the ATS must withstand and close on fault current, what upstream protection is used and whether a maintained or non-maintained neutral is needed. Ask for the exact RDQ1, RDH5D, RDWQ2, RDQH or RDQH5 model, controller, transfer time, utilisation category, short-circuit rating, terminal capacity, dimensions and model-level IEC 60947-6-1 evidence.
Official sources: RDH5D PC-class ATS · RDWQ2 high-current ATS · ATS product category · contact page.
4. Zhejiang Radin Electric Co., Ltd.
Short name: RADIN
Published location: No. 55 Punan 5 Road, Economic Development Zone, Yueqing
Radin states that it was established in 2005 and publishes a product tree dedicated to transfer switching: PC-class ATS, CB-class ATS, automatic changeover with current limiter, and manual transfer switches. Its RDS2 page describes a PC-class range from 63 A to 3,200 A, while the RDQ3NX page describes a CB-class switch with an MCB-based construction and an intelligent controller. This breadth is useful for comparing architectures, but the buyer should not mix the fault-breaking role of a CB-class ATS with the isolation and load-transfer role of a PC-class device.
Before requesting a quote: Specify AC or DC, the source arrangement, voltage, frequency, current, poles, neutral switching and load type. State whether the project requires PC class, CB class, manual operation or an automatic changeover limiter, and give the required transfer and delay times. Ask for the exact series and frame, controller functions, utilisation category, short-circuit withstand or breaking rating, upstream protection, terminal data, dimensions, IP rating and the applicable IEC 60947-6-1 report for the quoted model.

5. One Two Three Electric Co., Ltd. (YUYE)
Short name: YUYE
Published location: Wei No. 20 Road, Economic Development Zone, Yueqing
YUYE publishes a broad ATS programme that separates PC-class, CB-class and solenoid-operated families, and also lists ATS controllers and switch cabinets. Its YES1 PC ATS page gives a published working current up to 2,000 A, 3P or 4P configurations and AC-33iB/AC-33B categories, while the YEQ2Y CB ATS page describes a motor-driven 100–800 A range. The number of families makes model selection important: the controller, mechanism, pole configuration and short-circuit behaviour can differ even when the front-panel current rating looks similar.
Before requesting a quote: Provide the normal and backup sources, single-line diagram, voltage, frequency, current, poles and neutral arrangement. State whether the load needs PC-class, CB-class, solenoid or another mechanism, and define the required transfer, return and delay settings. Ask for the exact YES or YEQ model, controller model, utilisation category, short-circuit rating, terminal data, dimensional drawing, IP rating, certificate scope and the production site for the quoted variant.

6. HUYU Electric
Short name: HUYU
Published location: Wenzhou Bridge Industrial Park, Beibaixiang, Yueqing
HUYU publishes a dual-power ATS category with PC- and CB-class products, plus compact DIN-rail manual transfer switches. Its EXBZ7-63 page describes a manual 1-0-2 changeover switch from 16 A to 63 A in 1P to 4P configurations, while its ATS category lists larger products and controllers for mains-to-generator and other backup arrangements. The distinction matters: a small manual changeover switch for a DIN enclosure is a different product from a panel-mounted automatic transfer switch with sensing and control.
Before requesting a quote: State whether the requirement is manual or automatic, the normal and backup source, voltage, frequency, current and pole count. For an automatic unit, provide the required transfer time, controller functions, neutral arrangement and load type. For a manual unit, confirm the centre-off position, DIN-rail width, terminal capacity and enclosure requirement. Ask for the exact model, utilisation category, short-circuit data, dimensions, IP rating and the standard or certificate covering the quoted product.

7. Zhejiang GRL Electric Co., Ltd.
Short name: GRL
Published location: No. 66 Punan 5 Road, Yueqing Economic Development Zone
GRL publishes automatic, manual and DC transfer-switch categories. The DNH41 page describes an automatic 10–80 A unit for AC230 V with published switching times, while DNQ8 is presented as an isolated PC-class dual-power ATS and HGLZ as a manual transfer switch from 63 A to 3,150 A at AC400/690 V. The range is useful for comparing compact automatic products with large manually operated changeover switches, but those two duties should not be confused. Ask GRL to confirm the exact series and the current, pole and control configuration.
Before requesting a quote: Provide the application, source arrangement, voltage, frequency, current, poles and neutral requirement. State whether the device must operate automatically, manually or remotely, and give the required transfer time, centre-off position and control voltage. Ask for the exact DNH41, DNQ8 or HGLZ model, controller, utilisation category, fault-withstand or short-circuit data, terminal capacity, dimensional drawing, IP rating and model-specific certificate and test scope.

8. Zhejiang Mote Electric Co., Ltd. (MOTE)
Short name: MOTE
Published location: No. 205-26 Wei 12 Road, Yueqing Economic Development Zone
MOTE, also presented as Zhejiang Mote Electric, focuses on automatic transfer switching equipment and publishes XDQ1 through XDQ5 PC-class families using motor-driven or excitation mechanisms. Its public company profile describes ATSE applications in buildings, rail, industrial sites, hospitals, airports and data centres, and states that the company is involved in transfer-switch standards work. Those statements are company claims for the buyer to verify against the exact model evidence. The useful starting point is the XDQ mechanism, controller and source arrangement, not a single current rating.
Before requesting a quote: Send the single-line diagram, source types, system voltage, frequency, load current, poles and neutral arrangement. State the required transfer time, return delay, generator-exercise function, remote signalling and control voltage. Ask for the exact XDQ model, operating mechanism, controller, utilisation category, short-circuit withstand, terminal data, dimensions, IP rating, certificate holder, certificate scope and the production site for the quoted unit.

9. China Langming Electric Co., Ltd.
Short name: LANGMING
Published location: Yanyun Road 176, Wenzhou Marine Economic Development Demonstration Zone, Wenzhou
Langming presents itself as a specialist in intelligent dual-power automatic transfer switches and publishes several distinct families: SHIQ3-63 terminal and intelligent types, SHIQ5 and SHIQ5S isolated types, and an SW1-S intelligent universal-circuit-breaker transfer switch. Its company profile describes PC- and CB-class products and lists fire, building and industrial applications. The public contact page now gives a Wenzhou Marine Economic Development Demonstration Zone address rather than the older Liushi wording used in some catalogues, so confirm the legal entity and production site before treating it as a Yueqing factory visit candidate.
Before requesting a quote: Provide the source arrangement, single-line diagram, voltage, frequency, current, poles and neutral requirement. State whether the project needs a terminal, isolated PC-class or CB-class topology, and define the required transfer, return and delay settings. Ask for the exact SHIQ or SW1-S model, controller, utilisation category, short-circuit rating, terminal capacity, dimensions, IP rating, production address and model-level IEC 60947-6-1 evidence.
Official sources: Langming transfer-switch category · SHIQ3-63 transfer switch · SHIQ5 isolated transfer switch · contact page.
10. Yueqing Lovadon Electric Co., Ltd.
Short name: LOVADON
Published location: Building 1, No. 888 Liujiang Road, Beibaixiang, Yueqing
Lovadon publishes a dedicated automatic-transfer-switch category with compact CB-class NDQ2-63 products, PC-class NDQ5 frames from 100 A to 2,500 A and a DIN-rail ATSA-80 example. The published product titles also identify the pole count and rated current, which makes the range useful for building a first comparison group. Its contact page gives a Beibaixiang, Yueqing address. Because the same catalogue combines small DIN-rail and large panel-mounted products, the buyer should confirm the exact model instead of selecting by the family name alone.
Before requesting a quote: State the source arrangement, voltage, frequency, current, poles and neutral requirement. Confirm whether the project needs a CB-class, PC-class or DIN-rail ATS, and provide the required transfer time, controller functions and mounting space. Ask for the exact NDQ2, NDQ5 or ATSA model, utilisation category, short-circuit rating, terminal capacity, dimensions, IP rating, certificate scope and the production site for the quoted item.

Specify the transfer switch as a system
Two ATS products can carry the same current and voltage labels while having different source detection, contact mechanisms, neutral arrangements and fault responsibilities. Send every candidate the same single-line diagram and written schedule. Require the supplier to state deviations rather than choosing the cheapest unit by current rating alone.
| Include in your enquiry | Ask each supplier to confirm |
|---|---|
| Source arrangement | Utility-to-generator, utility-to-utility, generator-to-generator, two transformers or another arrangement; source voltage, phase rotation, frequency and neutral earthing. |
| ATS class and duty | PC class, CB class, manual, solenoid, motor-driven or STS; the required making, breaking, isolation and fault-withstand duty and the applicable product standard. |
| System ratings | Rated operational voltage, rated current, frame size, poles, switched neutral, frequency, utilisation category and short-time withstand or short-circuit rating. |
| Transfer performance | Transfer time, return time, delay settings, open or closed transition, dead-bus behaviour, centre-off position and the sequence after source failure and recovery. |
| Controller and sensing | Controller model, voltage and frequency sensing, phase failure and phase-sequence detection, under/over-voltage settings, generator exercise, remote start, communication and alarm outputs. |
| Fault coordination | Upstream and downstream protective devices, prospective fault current, short-circuit coordination, CB-class breaking role and whether the ATS is intended to withstand or interrupt fault current. |
| Neutral and earthing | 3P, 3P+N or 4P configuration, neutral switching, overlapping or break-before-make neutral, source earthing arrangement and any separately derived system requirement. |
| Terminals and wiring | Copper or aluminium conductor, cable or busbar size, terminal orientation, tightening torque, phase barriers, control-wiring terminals and the required bending space. |
| Mechanism and safety | Mechanical and electrical interlocking, manual emergency operation, position indication, padlocking, door interlock, arc containment and the procedure for maintenance. |
| Environmental and enclosure | IP rating, indoor or outdoor use, ambient temperature, altitude, humidity, corrosion exposure, ventilation and the enclosure or panel interface. |
| Standards and certificates | IEC 60947-6-1 or other declared standard, ATS class, certificate holder, number, exact model and production site covered; do not rely on a logo or general catalogue statement. |
| Drawings and lifecycle | Dimensional drawing, wiring diagram, controller manual, spare-parts list, firmware or controller revision, warranty and the route for replacement coils, motors, controllers or contacts. |
Do not compare a PC-class ATS with a CB-class ATS by current rating alone. The products can have different contact systems, fault behaviour, controller logic and upstream protection requirements. Ask the supplier to mark the exact class and model on the quotation, provide the coordination data and state whether an isolation function, bypass, neutral switching or external maintenance switch is required. For a generator system, also confirm the generator controller interface, start delay, cool-down sequence and any remote-start wiring.
Check the neutral and earthing design with the responsible electrical engineer. A four-pole switch does not automatically make an installation correct, and a three-pole switch may not be acceptable for every separately derived source. The same applies to control voltage: a controller listed for one voltage range should not be assumed to work with another control supply. Ask for the exact controller variant and test it against the system sequence before the panel is built.
What to inspect during a transfer-switch factory visit
Arrange the visit after the supplier has answered the technical schedule and identified the production site for the exact ATS model. Transfer-switch manufacturing can include contact and mechanism assembly, moulding, controller programming, interlock setup, wiring, routine operation and final testing. Observe the route that applies to your configuration rather than judging only a display unit.
- Bring the specification: include the single-line diagram, source arrangement, voltage, current, poles, neutral requirement, controller functions and required transfer sequence.
- Review incoming parts: check contact assemblies, springs, coils or motors, controllers, terminal blocks, interlock parts, mouldings and labels against the approved component list.
- Follow assembly: inspect contact alignment, mechanism travel, interlock adjustment, controller mounting, control wiring and terminal torque control.
- Observe routine tests: confirm manual operation, electrical operation, source-loss simulation, transfer and return sequence, position indication and the specified dielectric or functional checks.
- Check marking and traceability: review the model label, ATS class, ratings, wiring diagram, controller version, batch code and the link to the test record.
- Review accessories and documents: confirm the controller manual, wiring diagram, spare fuses or control parts, terminal covers, mounting hardware and packing configuration.
- What a visit proves: a factory visit provides observations and answers, not a product certification or a guarantee of future quality. Arrange model-specific type testing, market-access review and incoming inspection separately.

Questions transfer-switch buyers often ask
What is the difference between a transfer switch and a disconnect switch?
A transfer switch changes the load between two sources according to a defined sequence. A disconnect switch isolates a circuit or provides load-break isolation. Some transfer switches include isolation contacts, but the functions and standards are not interchangeable. Start with the source arrangement and the required switching duty, then select the product category.
What is the difference between PC-class and CB-class ATS?
PC-class and CB-class are different ATS constructions and should be selected with the electrical design. A CB-class ATS uses circuit-breaker constructions and may have a defined fault-breaking role, while a PC-class ATS is generally selected for transfer and isolation duty and relies on separate protection where required. Do not infer the class from the current rating or from a generic “ATS” label; ask for the declared class and test scope.
Can a manual transfer switch replace an automatic ATS?
Only if the operating procedure and system design allow manual intervention. A manual switch can be appropriate for a small workshop or a maintenance bypass, but it will not provide automatic source detection, generator starting or unattended transfer. Consider the load criticality, response time, operator availability and any requirement for remote monitoring.
Do I need a three-pole or four-pole transfer switch?
The answer depends on the source earthing arrangement, neutral configuration, local code and whether the installation has a separately derived system. A four-pole device switches the neutral, but that does not automatically make the design correct. Ask the responsible electrical engineer to define the neutral and earthing arrangement and require the supplier to confirm the contact configuration.
Should the ATS break fault current?
That depends on the ATS class, upstream protection and system coordination. Give the supplier the prospective fault current, upstream device, required withstand or breaking duty and the applicable standard. Do not assume that a high current rating alone establishes fault performance. Ask for the short-circuit rating and coordination table or test evidence for the exact model.
Can the ATS be used with a generator and a utility supply?
Yes, but the controller, source sensing, generator start signal, cool-down sequence, neutral arrangement and transfer delays must be designed for that arrangement. Provide a single-line diagram and the generator controller interface. Confirm whether the ATS is open-transition or closed-transition and whether the generator is permitted to operate in parallel with the utility.
Are these companies ranked by quality, price or export volume?
No. This is a research shortlist based on published product and location information. It is not a quality, price, certification, export or “best” ranking. Send every supplier the same technical schedule, compare deviations and documents, and verify the legal entity and production site before ordering.
