Engineered for high breaking capacities, custom trip parameters, and remote operations across industrial networks.
Founded in 2015, Acereare Electric operates through its two wholly-owned subsidiaries, "RuiRui Electric" and "KeRui Electric". Driven by the legacy of more than 20 years of craftsmanship inherited across two generations, we have established ourselves as one of the premier original equipment manufacturers (OEM) and original design manufacturers (ODM) of molded case circuit breakers (MCCB), air circuit breakers (ACB), and premium power distribution components in China.
Our operation scale leverages strategic digital tracking systems such as PLM, BI, ERP, and MES to link and synchronize all processes from engineering designs to automated assembly. We support over 100 high-end strategic customer brands worldwide, ensuring high performance, custom-engineered circuit breaker mechanisms, and absolute grid reliability.
Addressing the critical performance demands of heavy industries, renewable networks, and municipal utilities.
Modern electrical infrastructure demands circuit breakers capable of operating under highly variable currents without premature fatigue. Our thermal-magnetic and electronic MCCBs provide robust protection against short circuits and overloads, preserving structural transformer assets.
With solar and wind applications shifting systems up to 1140VAC and higher DC voltages, traditional breakers fail. Acereare delivers high-voltage MCCB models (like ARM5HU and dedicated solar MCCBs) rated for up to 1140V to meet the stringent safety profiles of utility-scale PV plants.
Industrial IoT requires edge computing and active remote control capabilities. By integrating LCD displays, RS485 communication protocols, and intelligent LSIG (Long, Short, Instantaneous, Ground fault) trip units, our breakers feed precise metrics directly to SCADA systems.
Why Tier-1 global distributors and engineering firms choose Acereare for wholesale electrical components.
One-stop production incorporating six core processing techniques. We operate state-of-the-art tooling machinery, high-precision injection molding, automatic contact stamping, and more than 10 manual and automated assembly lines.
Our team of over 50 R&D engineers brings 5+ years of specialized low-voltage apparatus design experience. We handle complete 3D parts modeling, mold fabrication, and execute 50+ new research and development design tasks every year.
Operating out of two major production facilities allows us to segment breaker components and finished machine lines. Logistics are managed dynamically via ERP and U8 software, ensuring uninterrupted delivery to ports worldwide.
Our internal laboratory features 150+ specialized test instruments and 20+ dedicated QC inspectors. Using digital quality tracking software, we enforce rigorous testing checkpoints on contact resistance, dielectric strength, and trip curve accuracy.
Custom environmental calibrations guaranteeing safe operation under harsh operating parameters.
We utilize specialized low-temperature resistant base materials and low-viscosity synthetic oils. Copper and structural elements undergo thick anti-embrittlement coatings, verified by comprehensive -40°C low-temperature test reports.
Designed to withstand marine air, we conduct 72-hour salt spray testing on complete machines and 48-hour testing on assemblies. Perfect for docks, marine propulsion cabinets, offshore wind terminals, and humid coastal setups.
At high altitudes, thin air reduces heat dissipation and dielectric breakdown levels. Our engineering team provides custom derating curves and high-insulation frame structures to maintain safety profiles in mountainous arrays.
Acereare MCCBs provide primary panel protection for sub-distribution layouts in high-rise apartments, complexes, and modern smart homes, isolating surges to avoid damage to consumer appliances.
Tested inside our integrated 55°C constant-temperature testing chamber, these breakers utilize high-glass transition temperature compounds, custom thermal-insulating barriers, and corrosion-resistant copper contacts.
