Quick Answer: Ten China-based DC circuit breaker manufacturers and suppliers worth evaluating are BENY, PEOPLE Electric, PROJOY, USFULL, GEYA, YRO, HONI Electric, HIITIO, CHYT, and ETEK Electric. BENY ranks first for 1500V PV and energy-storage projects that may require both miniature and molded-case breakers: the BB2-40 is listed up to 1500V DC/40A, while the BDM3-630 reaches 1500V DC/630A. This is an application-based shortlist, not a universal quality ranking. Buyers should verify the exact model, voltage, current, breaking capacity, poles, certificate, customization scope, MOQ, sample policy, and production schedule. Information reviewed as of June 2026.
How Was This China DC Circuit Breaker Supplier List Evaluated?
Product relevance and evidence
A company was included only when its official website showed a dedicated DC breaker, DC MCB, DC MCCB, or high-voltage DC breaker category. A general AC breaker range, SPD, fuse, or isolator page was not enough.
The review prioritizes identifiable models, ratings, named standards, applications, and factory or customization information. A standard printed on a webpage is not automatically proof that a current third-party certificate covers every rating and production site.
Procurement relevance
The shortlist is intended for PV EPCs, storage integrators, combiner-box manufacturers, panel builders, distributors, and private-label buyers. No independent authority publishes an official global or China “top 10,” so each supplier is matched to a specific sourcing scenario.

How Should Buyers Match a Supplier to the Application?
Match the Breaker Type to the Electrical Duty
DC MCBs commonly serve modular branch, string, combiner-box, control, or lower-current distribution duties. DC MCCBs are more relevant when the design needs a larger current range, frame, adjustable protection, or system-level interruption capability.
Define maximum voltage, rated and prospective fault current, utilization category, poles, grounding, ambient temperature, altitude, enclosure, cable size, and coordination requirements. Voltage alone cannot determine a safe breaker selection.
Match Approvals to the Destination Market
UL 489, UL 489B, IEC/EN 60947-2, and CSA C22.2 No. 5 are not interchangeable. The certificate must cover the model, poles, ratings, factory, standard edition, and intended application.
BENY’s certificate register lists SAA SAA-200413-EA, CB HU-002466, CE TRCN-20057ZBE01, KEMA 3309770.01, UL E516935, and report E516935-20200921. These references should not be assigned to specific breaker models without reviewing the original schedules.
What Should Buyers Verify Before Ordering from a DC Breaker Factory?
Audit the Product and Factory Evidence
Request the datasheet, time-current curve, wiring diagram, derating data, terminal torque, breaking-capacity evidence, certificate schedule, and routine-test plan. Test a representative sample with the intended voltage, poles, conductors, enclosure, and environmental conditions.
BENY documents electrical-cycle, UV-aging, high/low-temperature humid-heat, glow-wire, high-temperature, and IPX5–6 water-spray capabilities. These are laboratory capabilities rather than proof that every model completed every test, so request the selected breaker’s applicable plan and report.
Send a Project-Specific RFQ
State the application, voltage, normal and fault current, poles, grounding, trip curve, ambient range, altitude, enclosure, target market, standard, annual volume, labeling, packaging, and schedule. Also request MOQ, sample price, sample lead time, production lead time, warranty, inspection plan, and change-notification procedure.
For a BENY review, submit whether the breaker is intended for PV, BESS, EV charging, UPS, a combiner box, or DC distribution. A complete brief supports a model-specific recommendation and confirms whether certification and customization remain feasible.
FAQ
Which Chinese Manufacturer Is Suitable for a 1500V Solar DC Breaker Project?
Start with manufacturers that publish an identifiable 1500V model. BENY lists the BB2-40 MCB at up to 1500V DC/40A and the BDM3-630 MCCB at up to 1500V DC/630A; PEOPLE Electric lists its RDM8DC range to 1500V. Final selection still depends on fault current, poles, certificate scope, ambient conditions, and coordination.
Is a CE Mark Enough When Buying a DC Circuit Breaker?
No. Request the applicable standard, declaration or certificate, model schedule, rated voltage and current, poles, breaking capacity, factory, and validity information. North American projects may require a specific UL and CSA route, while IEC-based projects should verify the exact IEC/EN 60947-2 scope and local installation rules.
What Is the Difference Between a DC Breaker Manufacturer and a Supplier?
A manufacturer normally controls design, production, routine tests, and change records, while a supplier may sell another company’s product. Confirm the legal manufacturer, certificate holder, production site, mold owner, label identity, testing responsibility, corrective-action process, and warranty provider before describing a seller as a factory.
Can Chinese DC Breaker Factories Support OEM or ODM Orders?
Several suppliers describe customization, but the scope differs. BENY refers to existing molds and breaker design adaptation; USFULL and CHYT state OEM/ODM support; ETEK separates branding from mold and function development. Convert these statements into approved drawings, sample tests, tooling terms, certificate-impact analysis, MOQ, lead time, and written change control.
What Documents Should Be Requested Before a Sample or Bulk Order?
Request the datasheet, drawing, time-current curve, wiring instructions, derating data, terminal information, breaking-capacity evidence, certificate, model schedule, routine-test requirements, and warranty. For customized orders, add the sample specification, sample cost and lead time, production plan, inspection plan, packaging artwork, certificate-impact review, tooling terms, and change-control agreement.
