Manufacturer profiles and questions to ask
1. CHINT
CHINT publishes an MCB range, including its NB2 series, and its official factory overview identifies MCB and MCB core-component workshops in Wenzhou. It is a useful starting point when you want to compare an established branded range with other suppliers.
Before requesting a quote: Ask which legal entity will quote, which site manufactures the proposed model, and whether your order is handled directly or through an authorised distributor. The factory overview uses the wider Wenzhou location: confirm the exact Yueqing visit address before arranging travel.
Official sources: Product information · Company / location information.
2. DELIXI Electric
DELIXI Electric is a candidate for buyers seeking branded miniature circuit breakers and related distribution products. The DELIXI group contact page gives Delixi High-tech Industrial Park, Liushi Town, Yueqing as its location. Confirm the specific manufacturing entity and site for the MCB model you intend to order.
Before requesting a quote: Request the exact series, configuration and current datasheet. Confirm the supplying entity, production site and sales arrangements for your destination market before planning a visit.
Official sources: Product information · Company / location information.
3. People Electric
People Electric publishes miniature circuit breakers within its modular DIN-rail range. Its website identifies its headquarters in Yueqing and gives a Liushi contact address. Buyers sourcing several electrical categories can use the catalogue to assess whether a broader enquiry is appropriate.
Before requesting a quote: Ask the supplier to identify the production site and manufacturer shown on the documents for each product line. A broad group catalogue does not mean every item comes from the same production line.
Official sources: Product information · Company / location information.
4. Changan Group
Changan lists MCBs, RCCBs, RCBOs and other low-voltage products. Its website gives an address at No. 288, Wei 17 Road, Yueqing Economic Development Zone. This makes it a practical candidate to investigate when arranging local supplier meetings.
Before requesting a quote: Confirm the exact MCB family, available documents and sample lead time. If you also need residual-current protection, request a separate specification and quote rather than treating MCBs and RCBOs as the same product.
Official sources: Product information · Company / location information.
5. Singi Electrical
Singi publishes MCBs together with distribution boxes and other electrical products. Its contact page lists a Yueqing Economic Development Zone address east of No. 148, Wei 12th Road. Its catalogue is relevant to buyers considering breakers and enclosures in the same sourcing project.
Before requesting a quote: Check the intended enclosure, mounting arrangement and accessories with the proposed MCB. Ask for itemised pricing and confirm which products are manufactured at the site you plan to visit.
Official sources: Product information · Company / location information.
6. VIOX Electric
VIOX publishes an MCB comparison covering its VOB3-63, VOB3-63H and VOE3-63 series. Its contact page gives East Innovation Zone, Wengyang Town, Yueqing as its address. The comparison is a useful starting point for discussing which published series matches your buying requirements.
Before requesting a quote: Send the circuit type, rated current, pole configuration and quantity. Ask for the current model datasheet, quotation and applicable documentation; confirm any private-label requirements separately.
Official sources: Product information · Company / location information.
7. HUYU Electric
HUYU publishes miniature circuit breakers alongside other low-voltage protection products. Its product website lists Wenzhou Bridge Industrial Park, Beibaixiang Town, Yueqing as its address. Buyers can review its MCB offering as part of a broader modular circuit-protection enquiry.
Before requesting a quote: Confirm the exact AC or DC model, required accessories and applicable documents. Ask which production site will supply your order and arrange the visit with the responsible sales contact.
Official sources: Product information · Company / location information.
8. Suntree
Suntree publishes both AC and DC MCB categories. Its website gives No. 3 Siqian Road, Xinguang Industrial Zone, Yueqing as its address. It is relevant to a shortlist that includes photovoltaic or energy-storage electrical components as well as AC distribution products.
Before requesting a quote: Separate AC and DC enquiries. For a DC model, ask the supplier to confirm the operating voltage, required pole arrangement, wiring diagram and suitability for your intended circuit.
Official sources: Product information · Company / location information.
9. BENY
BENY’s official DC circuit-breaker page includes modular miniature circuit breakers alongside other DC breaker types. Its published address is in Wenzhou Daqiao Industry Park, Beibaixiang Town, Yueqing. Consider it specifically when your project includes solar DC protection.
Before requesting a quote: Specify that you are requesting a miniature circuit breaker, not a moulded-case or other DC breaker. Ask for the exact model documents and wiring requirements; do not infer an AC MCB offering from the DC range.
Official sources: Product information · Company / location information.
10. TENGEN Electric
TENGEN, known as Tianzheng in Chinese, lists miniature circuit breakers within its modular-device range. Its Chinese website features the TGB1N-63 MCB, and its international website gives Sulv Industrial Zone, Liushi Town, Yueqing as its address. Buyers can use these sources to start a focused product enquiry.
Before requesting a quote: Ask which series is offered for your destination market and request a model-specific datasheet and quote. Confirm the factory address, sample arrangements and documentation before booking a meeting.
Official sources: Product information · Company / location information.
Compare the same specification, not just the unit price
A useful quotation comparison starts with one written brief sent to every candidate. Keep the requested configuration and commercial terms consistent, and record each supplier’s exceptions beside the price.
| Include in your enquiry | Ask the supplier to confirm |
|---|---|
| Application and destination market | AC or DC use, intended circuit and required market documentation. |
| Electrical specification | Exact model, rated voltage, rated current, poles, trip characteristic and breaking capacity. |
| Product documentation | Current datasheet and applicable test or certification documents for that model and configuration. |
| Quantity and packaging | MOQ, order quantities, labelling, carton details and any customisation charges. |
| Samples and delivery | Sample cost, preparation time, production lead time and agreed delivery terms. |
| Quality and traceability | Sample approval process, batch identification, inspection scope and handling of nonconforming goods. |
Check that the manufacturer name, model designation and configuration on any document match the proposed purchase. A certificate logo in a catalogue is not enough to establish that the exact item in your quotation is covered. Ask for the underlying document and verify it through the issuing organisation where possible.
Turn the shortlist into a productive factory visit
Before travelling, narrow your enquiry to a few manufacturers that have answered your product questions and confirmed a meeting. An address on a website may be a sales office or headquarters; ask explicitly where the quoted product is made.
- Confirm the visit location: get the address, host’s name and agreed access to relevant production areas.
- Bring the buying brief: use the same specification and sample requirements discussed in the quotation.
- Agree the visit checklist: identify the production processes, available records and packaging details you want to review.
- Request permission for records: confirm whether photographs, videos and copies of documents are allowed.
- Record follow-up actions: assign each outstanding sample, document or revised quotation a contact and a due date.
A visit helps you understand the supplier and resolve questions. Product testing and certification are separate tasks; arrange them to suit your product and destination-market requirements.
Questions buyers often ask
Which Yueqing MCB manufacturer is the cheapest?
There is no reliable answer without comparable, current quotations for the same specification, quantity and delivery terms. Ask shortlisted suppliers for a written offer and compare exclusions as well as unit prices.
Can I order MCBs under my own brand?
Ask each manufacturer whether it accepts private-label orders for the selected model. Confirm the MOQ, artwork approval, product markings, packaging and documentation arrangements before placing an order. Inclusion in this list does not mean private labelling is available from every supplier.
Can BottomRace help arrange factory visits?
