Explore our premium grade molded case circuit breakers and electrical components engineered for reliable grid integration.
Global utility-scale solar installations are continuously pushing the envelope on system voltages. Transitioning from traditional 400V/690V AC outputs to 800V AC is a major industry solution to reduce Balance of System (BOS) costs, optimize cabling sizes, and decrease transmission line losses. Consequently, the demands placed on protection systems have increased significantly.
Molded Case Circuit Breakers (MCCBs) designed specifically for solar topologies must provide infallible electrical isolation, short-circuit current limitation, and thermal protection under persistent DC and high-frequency AC stress. As a premier China manufacturer, Acereare has designed high-performance circuit protection devices that resolve the issues of elevated ambient temperatures and harmonic distortion typical of solar inverter stations.
Established in 2015, Acereare Electric operates through its two wholly-owned manufacturing subsidiaries: RuiRui Electric and KeRui Electric. With a deep foundation in engineering precision and high-voltage circuit design, we specialize in the design, development, and production of Molded Case Circuit Breakers (MCCB), Air Circuit Breakers (ACB), and auxiliary component stamps.
Our craftsmanship heritage extends back over 20 years, spanning two generations of dedicated electrical development. Today, we rank among the leading ODM/OEM partners in China, helping grid operators, EPC contractors, and global power distributors configure reliable circuit protection platforms.

Solar arrays and power grids operate in the most demanding conditions globally. We engineer our MCCB solutions to ensure uninterrupted performance across multiple environmental challenges.
For installations in high-latitude environments or cold highland regions, we implement specialized low-temperature resistant lubrication, customized synthetic polymers, and thickened protective surface coatings. Our breakers maintain structural integrity and trip reliability even at temperatures as low as -40 °C.
Offshore floating solar arrays and coastal solar grids must resist salt air corrosion. Our MCCB devices undergo a comprehensive 72-hour salt spray test for fully completed units and a 48-hour test for semi-assemblies, preserving contacts from high humidity degradation.
When operating above an altitude of 2000 meters, air density drop impacts insulation capability and heat dissipation. We provide specialized derating calculations to modify the MCCB parameter performance, preserving breaker longevity in high-altitude arrays.
Desert solar plants routinely experience indoor ambient temperatures over 50 °C inside inverter cabins. Acereare circuit breakers deploy thermal-insulating barriers on controllers and utilize high-conductivity copper busbars calibrated inside our 55 °C constant-temperature rooms.
Our MCCB solutions are designed for smart grid architectures, providing measurement, remote diagnostics, and Edge Computing telemetry. These micro-controller equipped breakers transmit electrical data over RS485 or Modbus channels, supporting modern remote operations.
Beyond massive utility arrays, our MCCB systems are widely utilized to secure residential battery energy storage (BESS) and distribution cabinets, preventing circuit damage from catastrophic short circuit and overload faults.
For international buyers, developers, and solar EPC companies, sourcing certified 800V MCCB switchgear is crucial for plant safety and compliance. We address the core procurement objectives: long operational lifespans, minimum maintenance, and strict adherence to global safety codes.
Our products are engineered to conform to global specifications including IEC 60947-2 and regional safety marks. In solar installations, the high rate of load changes and transient overvoltages requires breakers with excellent electrical and mechanical durability. Our facilities incorporate automatic stamping, automated assembly lines, and micro-computer calibration equipment to deliver product consistency across large production runs.
Our product roadmap addresses the rising demand for higher voltage AC circuits. While 800VAC remains standard for high-performance string inverters, our research group is advancing developments for 1140VAC systems to support future solar generation architectures.
