Explore our premium industrial-grade molded case circuit breakers designed for optimized protection in photovoltaic solar installations.
Global photovoltaic systems are shifting rapidly from traditional 400V/690V systems toward 800VAC / 1500VDC architectures. This evolution is driven by the need to minimize transmission losses, reduce cable cross-sections, and optimize the integration of large capacity central and string inverters.
In utility-scale installations, implementing an 800VAC circuit protection mechanism enables solar plants to achieve significant balance-of-system (BOS) savings. Standard low-voltage circuit breakers fail under the thermal and electrical stress generated by 800V AC architectures. Our specialized Photovoltaic Molded Case Circuit Breakers (MCCB) are engineered exactly to provide reliable interruption capabilities, high dielectric strength, and long-term performance under demanding cyclic thermal profiles.
Founded officially in 2015, Acereare Electric integrates the strategic manufacturing assets of "RuiRui Electric" and "KeRui Electric", both wholly-owned subsidiaries. Rooted in over 20 years of generational industrial electrical craftsmanship, we are an OEM/ODM giant in low-voltage electrical protection apparatus in Wenzhou, China.
Our comprehensive, vertically-integrated facilities scale from high-precision components (including internal silver contacts, metal stampings, and molded chassis) to completely assembled, intelligence-enabled molded case circuit breakers and air circuit breakers (ACB).
A closer look at how we utilize advanced enterprise systems and strict physical validation parameters to ensure zero-defect product runs.
One-stop service spanning 6 advanced processing technologies. We employ automated and manual assembly lines with precision tooling and custom jigs to ensure uniform torque and tolerance limits.
50+ engineers with a minimum of 5 years of field experience utilize advanced 3D FEA (Finite Element Analysis) tools to simulate mechanical linkages, arc extinguish paths, and thermal dynamics.
Operations are governed by consolidated ERP and U8 logistics frameworks, allowing material batch tracing from crude copper or silver and plastics to the dispatched end-product.
Equipped with over 150 dedicated testing instruments managed by 20+ specialized QC inspectors. We validate breaking thresholds, mechanical life, and environmental degradation parameters.
Our circuit breakers are optimized for harsh, variable external environments where typical low-voltage gear fails.
Specially formulated cold-resistant synthetic resins, thickened high-viscosity low-temperature lubricants, and custom zinc-nickel coatings enable reliable operation down to -40℃ without mechanical freezing or structural embrittlement.
Validated through 72-hour salt spray testing on complete machines and 48-hour testing on sub-assemblies. Protects vital elements from humid, ionized coastal atmosphere, ensuring safety in dockside operations, offshore setups, and seaside PV fields.
Above altitudes of 2000m, rarefied air affects dielectric heat dissipation and arc extinction. We map precise calibration charts utilizing custom high-altitude derating variables to adjust current ratings and dielectric thresholds appropriately.
Ensuring maximum flexibility and modular sizing to fit within standard distributions panels. Provides primary overcurrent protection and fast arc interruption for smart home and building automation systems.
Using thermosetting materials that maintain physical integrity up to 55°C within sealed panels. Metal parts are chemically treated to remain stable and avoid heat-induced degradation or thermal drifting in arid zones.
Integrated microprocessors support real-time digital current measurement, system telemetry, and remote status feedback. Features communication bus interfaces to form the foundation of cloud-managed power grid assets.

How Acereare aligns with global regulatory standards to support solar distribution system integration.
Electric grids in the EU, APAC, and the Americas enforce strict codes concerning low-voltage ride-through (LVRT) and harmonic tolerances. Acereare's 800V AC MCCB ranges are built to satisfy the IEC 60947-2 international testing criteria:
| Standard Code | Core Requirement | Acereare Compliance Level |
|---|---|---|
| IEC 60947-2 | LV Industrial Breakers | Full Type Tested (CE declared) |
| UL 489B | Photovoltaic Protection | Design alignment for system integration |
| GB/T 14048.2 | National Chinese Grid Std | CCC Certified (RuiRui & KeRui) |
