Looking for disconnect switch manufacturers in Yueqing? This guide profiles ten local companies that publish low-voltage switch-disconnectors, fuse switch-disconnectors, knife switches or load-break switches and a Yueqing address. It covers modular isolators, industrial rotary switches, fuse-protected disconnectors, panel-mounted handles and enclosed isolation products.
In this guide, a disconnect switch means a low-voltage device used to isolate a circuit, or in some designs to make and break normal load current as a switch-disconnector. It is not the same as an MCB, MCCB, ACB or high-voltage disconnector. Those products have different protection, arc-control and system roles. Some Yueqing companies make several categories, so name the function and voltage class 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 the NXHB-125 as a switch disconnector for final power distribution, with 1P, 2P, 3P and 4P variants shown in its official product assets. The product family is positioned for isolation and control in low-voltage distribution rather than overload or short-circuit protection. That distinction matters when a panel builder is choosing a main isolator or a local disconnect ahead of another protective device. Confirm the exact pole arrangement, rated current, mounting accessories and the short-circuit coordination required by the panel design.
Before requesting a quote: State the system voltage, frequency, number of poles, switched neutral requirement, rated current and utilisation category. Provide the upstream protective device, prospective short-circuit current and required short-circuit coordination. Ask for the terminal capacity, torque, panel cut-out, operating mechanism, accessory list and the model-specific IEC 60947-3 evidence.
Official sources: NXHB-125 switch disconnector · contact page.
2. DELIXI Electric
Short name: DELIXI
Published location: Delixi High-tech Industrial Park, Liushi, Yueqing
DELIXI publishes the HR17 as a fuse disconnecting switch for distribution and motor circuits with high short-circuit current. Its official product information describes it as a power switch, isolating switch, emergency switch and circuit-protection device, while noting that it is generally not intended to start and stop a single motor directly. Published characteristics include 100–630 A, 400/690 V and AC-23B/AC-22B use. The fuse type and coordination are part of the electrical design, not just an accessory choice.
Before requesting a quote: Specify the rated operational voltage, current, number of poles, utilisation category and whether the device must break load or provide isolation only. Name the fuse size, type, rating and breaking capacity, and provide the prospective fault current. Ask for the fuse coordination table, terminal and cable range, handle and padlocking arrangement, IP rating and the exact HR17 variant and certificate scope.
Official sources: HR17 fuse disconnecting switch · Switch-disconnector range · contact page.
3. TENGEN Group Co., Ltd.
Short name: TENGEN
Published location: Sulv Industrial Zone, Liushi, Yueqing
TENGEN's official disconnector page groups several distinct families: HR17N fuse switch-disconnectors, GL load-break switches, HD11 and HS11/B knife switches with protective covers, and HD/HS knife switches. The published ranges extend from small 63 A devices to high-current 3,000 A and 3,150 A families, with different pole counts and voltage limits. That breadth should not be treated as one interchangeable product line. Start with the switching duty, fuse requirement, enclosure space and operating mechanism, then select the correct family.
Before requesting a quote: Provide the application, AC or DC system, voltage, rated current, poles, switched neutral, utilisation category and whether a fuse is required. State the mounting orientation, panel or enclosure type, handle position, padlocking and visible-isolation requirement. Ask for the exact series and model, terminal and cable capacity, short-circuit coordination, IP rating, drawings, catalogue and model-level test information.
Official sources: Disconnector switches · Isolating switches and load switches · contact page.
4. HUYU Electric (Huanyu High-Tech)
Short name: HUYU
Published location: Wenzhou Bridge Industrial Park, Beibaixiang, Yueqing
HUYU publishes a dedicated low-voltage disconnector and knife-switch category alongside modular isolator switches. Its wider low-voltage range includes distribution devices and industrial control products, so buyers should distinguish a conventional knife-switch assembly from a modular isolator intended for a DIN-rail board. The official company information identifies the manufacturing location at Wenzhou Bridge Industrial Park in Beibaixiang, Yueqing. Ask for the exact series and enclosure interface before comparing prices.
Before requesting a quote: Send the single-line diagram or a clear description of where the switch sits: incoming isolator, feeder isolation, motor circuit or maintenance point. State AC or DC, voltage, current, poles, fuse requirement and utilisation category. Ask for the mounting method, terminal capacity, handle and door interlock, padlocking feature, IP rating, dimensions and model-specific standards and test documents.
Official sources: Disconnectors and knife switches · Modular isolator switches · contact page.
5. Zhejiang GRL Electric Co., Ltd.
Short name: GRL
Published location: No. 66 Punan 5 Road, Yueqing Economic Development Zone
GRL was founded in 2003 and publishes fuse switch-disconnectors, AC and DC isolators, knife switches and PV isolators. Its named families include DNH1, DNH7, HR6 and HGL, with separate pages for vertical and 1P fuse switch-disconnectors. The company profile also describes busbar systems and fuse products, which can be useful when the disconnector has to integrate with a specific fuse base or busbar assembly. The fuse standard, size and coordination must still be confirmed for the exact model.
Before requesting a quote: State whether the device is for AC or DC, the system voltage and current, number of poles and utilisation category. Name the fuse standard, size, rating and breaking capacity, plus the required busbar, cable or terminal connection. Ask for the DNH1, DNH7, HR6 or HGL model drawing, short-circuit coordination, IP rating, handle and padlock details, accessory list and the production site for the quoted item.
Official sources: Fuse switch-disconnector range · DNH1 fuse switch-disconnectors · Company profile · contact page.
6. People Electrical Appliance Group Co., Ltd.
Short name: PEOPLE
Published location: No. 555 Liule Road, Liushi, Yueqing
PEOPLE was founded in 1986 and is headquartered in Yueqing. Its official English catalogue separates low-voltage disconnectors from medium- and high-voltage disconnectors and also lists isolating switches. That separation is important: a product placed under a broad “disconnector” heading may belong to a different voltage class or application. For a low-voltage panel, ask for the exact series, rated operational voltage and current, pole count, utilisation category and the switching or isolation duty that the device has been designed to perform.
Before requesting a quote: Provide the low-voltage system details, including voltage, frequency, current, poles and neutral arrangement. State whether the device must make and break normal load current, isolate a circuit or combine isolation with fuse protection. Ask for the specific model, terminal capacity, mounting dimensions, operating handle, padlocking, IP rating, short-circuit coordination and the relevant IEC 60947-3 test evidence.
Official sources: Low-voltage disconnector range · Isolating switch range · contact page.
7. Zhejiang Kripal Electric Co., Ltd.
Short name: KRIPAL
Published location: Zhongfang Intelligent Industrial Park, Beibaixiang, Yueqing
KRIPAL publishes a focused isolating-switch series covering UKP panel-mount devices, UKPN load isolating switches, UKPA aluminium-enclosure isolators and UKPS metal-enclosed isolators. The official UKPA page describes an aluminium casting designed for demanding environments and states compliance with GB/T 14048.3 and IEC/EN 60947-3. The existence of several enclosure formats means the buyer should start with the installation environment, handle access and IP requirement rather than selecting by current alone.
Before requesting a quote: Specify indoor or outdoor use, panel-mount or enclosed format, AC or DC, voltage, current, poles and switched neutral. State the required IP rating, cable entry, terminal capacity, handle position, door interlock and padlocking. Ask for the exact UKP, UKPN, UKPA or UKPS model, enclosure material, dimensions, utilisation category, short-circuit information and model-level certificate and test scope.
Official sources: Isolating switch series · UKPA isolating switch · AC isolator switch range · contact page.
8. Yueqing Chengyang Electric Co., Ltd.
Short name: Chengyang
Published location: Liushi, Yueqing (confirm exact factory address)
Chengyang publishes HR17 fuse switch-disconnectors, CYH5 vertical fuse switch-disconnectors and CYD1 DC disconnect switches. Its HR17 page describes a 40–630 A range at 380/660 V and references IEC/EN 60947-3, while the CYH5 range is presented for AC systems up to 690 V. The company identifies Liushi, Yueqing as its base, but its public pages do not consistently expand the street-level address. Treat the quoted legal entity and factory address as items to verify in the proforma invoice and audit.
Before requesting a quote: State AC or DC, voltage, current, poles, fuse size and whether the device is for distribution, motor circuit or photovoltaic isolation. Ask for the exact HR17, CYH5 or CYD1 model, utilisation category, terminal range, mounting dimensions, IP rating, handle and padlocking, short-circuit coordination and certificate scope. Request the full legal entity, production address and model-level test report before placing an order.
Official sources: HR17 fuse switch-disconnector · Product centre · contact page.
9. Yueqing Yijin Electronics Co., Ltd.
Short name: Yijin
Published location: Building 7, No. 1 Lihong Avenue, Yueqing Bay, Wenzhou
Yijin was established in 2010 and publishes an isolating-switch category containing HD11F-250 protective opening knife switches and HK18-125 and HK18-160 photovoltaic knife switches. The combination of general-purpose and PV-specific products should prompt a clear application check: a DC isolator for a PV string is not interchangeable with an AC knife switch used in a distribution panel. The official contact page gives a Yueqing Bay address and identifies the company as a low-voltage electrical appliance manufacturer.
Before requesting a quote: Provide the AC or DC system, maximum voltage, current, poles and load type. For PV, state the string voltage, current, isolation requirement, enclosure rating and applicable DC utilisation category. Ask for the HD11F or HK18 model drawing, terminal capacity, mounting method, visible isolation, handle and padlocking, IP rating and model-specific certificate and test evidence.
Official sources: Isolating switch category · Product catalogue · contact page.
10. VIOX Electric
Short name: VIOX
Published location: First Building, East Innovation Zone, Wengyang, Yueqing
VIOX publishes LW26 rotary cam switches from 10 A to 315 A and LW30 load-disconnect switches from 20 A to 100 A. The product pages describe configurable contact programs, panel mounting and load-switching or isolation duties at published AC and DC voltages. Rotary switches are application-specific: the position sequence, contact configuration, make-before-break behaviour and handle marking must match the circuit. A generic “LW26” reference is not enough to define a usable switch.
Before requesting a quote: Send the switching diagram, contact truth table, required positions, AC or DC voltage and current per contact, load type and utilisation category. Specify panel depth, handle and shaft length, terminal arrangement, IP rating and any padlocking or door-interlock requirement. Ask for the exact LW26 or LW30 model, configuration drawing, rating per contact, test standard and production address.
Official sources: Rotary cam and load-disconnect switches · LW26 rotary cam switch · LW30 load-disconnect switch · contact page.
Specify the disconnect switch, not just the current rating
Two switches can share the same current and voltage labels while serving different duties. One may be an isolation device with visible contacts; another may be a switch-disconnector rated to break load current; a third may include a fuse or be designed for DC. Send every candidate the same requirements and require written deviations. The schedule below covers the details that most often change the price, fit or approval scope.
| Include in your enquiry | Ask each supplier to confirm |
|---|---|
| Application and switching duty | Isolation only, load make-and-break, frequent or infrequent operation, emergency switching, motor-circuit isolation, distribution isolation or photovoltaic DC isolation; name the load type and duty. |
| System and ratings | AC or DC, rated operational voltage, rated current, frequency, number of poles, switched neutral, utilisation category and any required short-time withstand current. |
| Fuse or protection | Fuse standard, size, class, current rating and breaking capacity; whether the switch includes a fuse carrier; and the coordination required with upstream or downstream protective devices. |
| Isolation and contacts | Visible isolation, contact position indication, positive opening, minimum contact gap, terminal shrouds, phase barriers and the meaning of the handle position markings. |
| Operating mechanism | Direct handle, side handle, door-mounted handle, shaft length, extension kit, defeat mechanism, padlocking in the off position and any door interlock or early-break auxiliary contact. |
| Mounting and enclosure | Panel-mount, DIN-rail, base-mount, enclosed or metal-enclosed format; mounting orientation, cut-out, depth, cable entry, terminal access and available panel space. |
| Terminals and wiring | Terminal type, maximum cable or busbar size, tightening torque, cable lug clearance, phase sequence, incoming and outgoing terminal positions and whether terminal covers are included. |
| Environmental protection | IP rating at the installed boundary, enclosure material, UV exposure, ambient temperature, humidity, corrosion resistance and suitability for indoor or outdoor use. |
| Electrical tests | Temperature rise, dielectric strength, making and breaking capacity, short-time withstand, mechanical endurance, IP test and any DC-specific test evidence for the exact model. |
| Standards and certificates | IEC 60947-3 or other declared standard, certificate holder, certificate number, product model and production site covered; do not rely on a logo or a generic catalogue claim. |
| Dimensions and drawings | Dimensional drawing, panel cut-out, handle clearance, terminal drawing, fuse carrier drawing, accessory list and the installation manual for the selected variant. |
| Production and change control | Legal entity, factory address, approved materials and components, model revision, change-notification rules, warranty and the route for spare handles, fuses or accessories. |
Do not compare disconnect switches by front-panel appearance or a single current rating. A 63 A isolator, a 63 A fuse switch-disconnector and a 63 A load-break switch can have different contact systems, terminal sizes, fuse carriers, utilisation categories and fault-coordination requirements. Ask for the exact model drawing, the fuse or short-circuit data, and confirmation that the device is suitable for the intended AC or DC duty.
For a panel builder, check the space around the handle as well as the device itself. A door-mounted operating mechanism may need a shaft, extension, door interlock and padlock hasp that are not included in the base switch price. For a fuse switch-disconnector, confirm whether the quoted fuse is included and whether its breaking capacity matches the prospective fault current. For a photovoltaic isolator, use DC-rated products and verify the polarity, string voltage and DC utilisation category; an AC-rated knife switch is not a substitute.
What to inspect during a disconnect-switch factory visit
Arrange the visit after the supplier has answered the technical schedule and identified the production site for the exact model. Disconnect-switch manufacturing may combine contact assembly, spring adjustment, moulding, fuse-carrier assembly, marking and routine testing, so observe the route that applies to your product instead of judging only the showroom sample.
- Bring the specification: include AC or DC, voltage, current, poles, fuse type, utilisation category, mounting method, handle arrangement and the required certificate scope.
- Review incoming parts: check contacts, springs, terminals, operating shafts, handles, mouldings, fuse carriers and labels against the approved component list.
- Follow assembly: inspect contact alignment, spring installation, terminal torque control, mechanism lubrication, handle operation and fuse-carrier fit.
- Observe routine tests: confirm mechanical operation, contact indication, dielectric strength, terminal pull-out or torque checks and any functional test specified for the model.
- Check marking and traceability: review the model label, ratings, wiring or operating diagram, batch code, production order and link to the test record.
- Review packaging and accessories: check that handles, shafts, terminal covers, fuses, screws and installation sheets are packed in the agreed 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 disconnect-switch buyers often ask
What is the difference between a disconnect switch and a circuit breaker?
A disconnect switch is selected primarily for isolation and, in some designs, for making and breaking normal load current. A circuit breaker is designed to interrupt fault current and provides overcurrent protection within its declared ratings. A switch-disconnector combines isolation with load-switching ability, but it still does not replace a circuit breaker unless the product standard and the system design explicitly allow that arrangement.
When should I choose a fuse switch-disconnector?
A fuse switch-disconnector combines isolation and fuse protection in one assembly. It can be useful where the fuse type, coordination and replacement process fit the panel design. Give the supplier the prospective fault current, fuse standard, fuse size and breaking capacity, and check whether the fuse is included. The switch and fuse must be selected as a coordinated system, not as two unrelated parts.
Does a visible handle position prove that the circuit is isolated?
No. The handle position is an indication, not a substitute for the product’s isolation design, installation procedure and lockout/tagout process. Ask for visible isolation, contact indication, positive opening and the applicable standard. Confirm that the switch is installed in the correct orientation, that all poles are isolated as required and that the handle can be padlocked in the off position.
Can an AC disconnect switch be used for a photovoltaic system?
Do not assume so. PV circuits are DC and can require a DC-rated isolator with the correct voltage, current, polarity and utilisation category. Ask for the DC rating and test evidence for the exact model, and confirm whether the device is suitable for the string voltage and expected fault conditions. The fact that a product is sold as an “isolator” does not establish DC suitability.
Which utilisation category should I specify?
The utilisation category describes the load and operational duty covered by the rating, such as a particular AC or DC load type. It should come from the application and the applicable standard, not from a preference for the highest number. Give the supplier the load type, switching frequency and expected overload or fault conditions, then compare the declared category and test evidence for the exact model.
What should be included in the quotation?
The quotation should identify the legal entity, factory address, exact model, poles, voltage, current, utilisation category, fuse type and rating if applicable, handle and shaft length, terminal capacity, IP rating, accessories and the standard or certificate claimed. Ask for the dimensional drawing and confirm whether the fuse, terminal cover, door interlock and mounting screws are included.
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.
