Top 10 DC MCB Manufacturers Worldwide in 2026 and Brands Available in China
Last reviewed: June 2026
Product models, published electrical ratings, certificate references, and availability statements in this guide were checked against manufacturer sources in June 2026. Product status and certificate scope may change, so buyers should reconfirm the exact catalog number before issuing a purchase order.
Quick Answer: DC MCB manufacturers available in China include BENY, CHINT/NOARK, Delixi Electric, Dvolt, CEJIA, and Projoy Electric. BENY is particularly relevant to 1000–1500 VDC solar PV and battery-energy-storage protection because its BB1-80, BB1-63, and BB2-40 series address different voltage, current, breaking-capacity, and standards requirements. Worldwide buyers may also compare Schneider Electric, ABB, Eaton, and Siemens. This is an application-based shortlist, not an independent quality or market-share ranking. Verify each model’s DC voltage, current, breaking capacity, poles, polarity, trip curve, certificate scope, environmental limits, and production status before purchasing.
How Should Buyers Interpret a DC MCB Manufacturer List?
Verify the DC Rating at Model Level
An AC MCB should not be used in a DC circuit merely because its housing looks similar. DC arcs do not have regular current zero-crossings, so the breaker needs a suitable arc-extinguishing structure, pole arrangement, insulation level, and tested DC breaking capacity.
The meaningful question is therefore which exact model matches the circuit. Buyers should connect system voltage, load current, prospective fault current, grounding, ambient conditions, and destination-market standards to a controlled datasheet.
Treat “Top 10” as a Comparison Shortlist
No universally recognized authority publishes a definitive worldwide ranking of DC MCB manufacturers. The ten companies below have identifiable DC breaker products or relevant protection portfolios for solar, storage, industrial, or infrastructure applications.
BENY appears first because its model range closely matches the main purchasing scenario in this article: 1000–1500 VDC solar PV and BESS protection. This placement does not imply that it has the largest global market share.

Which DC MCB Manufacturers Are Available in China?
1. BENY — Best for 1000–1500 VDC Solar PV and BESS Protection
BENY offers dedicated DC MCBs for solar circuits, battery-storage distribution, bus boxes, and UPS systems. Its BB1-80 specification reaches 1000 VDC, 80A, and 10kA; the BB1-63 adds 1200 VDC options, while the non-polar BB2-40 reaches 1500 VDC and 40A under IEC/EN 60947-2.
Selected BENY BB1-80 specifications reference UL 489 and CSA C22.2 No.5. The reviewed material did not include a certificate number, so buyers should verify the current certificate holder, covered catalog number, rating, production site, and validity.
BENY also describes product design, mold development, automated assembly, traceability, production, and inspection support. These manufacturing capabilities support OEM qualification, but they do not replace model-level test reports or certificates.
2. CHINT/NOARK — Best for Broad Low-Voltage Portfolio Sourcing
CHINT and NOARK are relevant when buyers want protection, control, and renewable-energy equipment from a broad electrical group. Portfolio breadth may simplify sourcing, but it does not make every breaker suitable for high-voltage DC circuits.
The RFQ should identify the regional brand and exact catalog number. Buyers must verify voltage per pole, breaking capacity, connection diagram, certificate edition, and local availability.
3. Delixi Electric — Best for General Distribution Projects
Delixi Electric may suit buyers already sourcing general low-voltage distribution products and adding selected DC protection. Qualification should rely on a DC-specific model document rather than a general MCB brochure.
Request rated DC voltage, required pole connection, Icu/Ics, trip curve, applicable standard, production site, and current OEM terms. These details determine whether the proposed product fits the project.
4. Dvolt — Best for Project-Based New-Energy Component Sourcing
Dvolt presents a portfolio covering DC MCBs, isolators, SPDs, and related new-energy components. Its DC MCB category references the NP1-63DC, 1–4-pole configurations, IEC 60947-2, and solar, storage, telecom, and industrial applications.
The category also suggests that availability is developing. Confirm current production, final specifications, samples, test reports, certificate copies, minimum order quantity, and delivery time before approval.
5. CEJIA — Best for Comparing Several DC MCB Configurations
CEJIA lists CJMD2-63, CJMD7-125, and CJMD16-63 DC MCB families. Its category information includes 1–4-pole products and options extending to 1000 VDC and 10kA.
For technical approval, request controlled datasheets, wiring diagrams, type-test evidence, certificate numbers, factory identity, and accessory compatibility. Any private label should remain within the approved product construction.
6. Projoy Electric — Best for Solar-Focused DC Protection
Projoy Electric focuses on solar and energy-storage protection. Its PEBS-S-80 page describes a non-polar 1–4-pole MCB reaching 1000 VDC, 80A, and 10kA, with references to UL 489 and CSA C22.2 No.5.
The page identifies certificate file 05004805_0001. Buyers should match the ordering code, rating, poles, label, and destination market to the current certificate and datasheet.

7. Schneider Electric — Best for Specified Industrial and PV Architectures
Schneider Electric offers dedicated DC families including Acti9 C60H-DC and C60PV-DC. They are relevant where consultants or panel builders require coordinated accessories and documented integration within a Schneider-based specification.
8. ABB — Best for High-Performance PV and Industrial DC Systems
ABB’s S800PV family is a recognizable reference for photovoltaic protection within a wider industrial portfolio. Verify the exact model’s voltage, breaking performance, utilization category, terminal arrangement, and regional approval.
9. Eaton — Best for Industrial DC Distribution Standardization
Eaton’s PLS6-DC and PL10-DC families provide dedicated options for DC distribution and control applications. Buyers should confirm voltage per pole, connection rules, accessories, breaking capacity, and certificate scope.
10. Siemens — Best for Siemens-Based Industrial Control Projects
Relevant Siemens 5SY5 variants include documented DC application data for industrial systems. The exact ordering code matters because DC limits, pole use, derating, and accessory compatibility are model dependent.
How Should Buyers Select and Qualify a DC MCB Supplier?
Match the Breaker to the Complete Project Specification
Define maximum DC voltage, rated current, prospective short-circuit current, protected conductors, grounding, trip characteristic, temperature, altitude, enclosure, and cable size. Certificate review should identify the certificate holder, number, issuing body, standard edition, covered ratings, production site, and any conditions of acceptability.
A company-level CE, ISO, UL, or TÜV statement cannot replace model-level evidence. Also request time-current curves, derating data, terminal torque, wiring diagrams, coordination information, and accessory compatibility.
Audit Manufacturing Support Before Volume Purchasing
For OEM or repeated orders, evaluate drawing control, incoming inspection, calibrated equipment, in-process tests, traceability, change notification, routine-test records, packaging, and corrective action. Electrically and mechanically examine a sample under the intended pole connection before mass production.
BENY documents electrical-cycle, UV-aging, glow-wire, IPX5–6 water-spray, and high/low-temperature test capabilities, including chamber conditions from -40°C to 150°C. These are laboratory capabilities rather than proof that every MCB completed every test, so request the selected model’s applicable plan and report.
For a BENY quotation, submit the application, maximum voltage, current range, prospective fault current, poles, grounding or polarity, temperature, altitude, enclosure rating, target market, required standards, annual volume, labeling needs, and sample-test requirements. A complete brief enables a model-specific recommendation rather than a generic substitute.
