High-performance engineering designed to protect industrial, commercial, and utility grids from short circuits and thermal overloads.
Founded in 2015, Acereare Electric operates as a leading high-tech manufacturer specializing in low-voltage and high-voltage circuit protection components. Supported by two wholly-owned subsidiaries—RuiRui Electric and KeRui Electric—our corporate footprint blends twenty years of intergenerational electrical expertise with advanced technological modernization. Today, we rank among China's premier original design manufacturers (ODMs) and original equipment manufacturers (OEMs) for Molded Case Circuit Breakers (MCCBs) and Air Circuit Breakers (ACBs).
From component stamping and thermal-trip calibration to electronic chip programming, we run integrated vertical manufacturing facilities. This allows us to strictly monitor production costs and quality parameters, establishing ourselves as trusted strategic partners for over 100 high-end electrical brands worldwide.
Four pillars of reliability supporting heavy industries, EPC contractors, and global distributors.
We provide a comprehensive production workflow featuring six processing techniques. Our factories utilize high-precision equipment and automated calibration systems alongside more than 10 manual and automated assembly lines to keep defect rates near zero.
Our team of 50+ R&D engineers, each possessing over 5 years of industry experience, designs complex structural models and molds using advanced 3D CAD/CAE software. We complete more than 50 technical research and product custom projects annually.
Operating two dedicated manufacturing centers allows us to produce internal electrical components and final products under one system. We optimize production tracking and delivery windows using integrated ERP and U8 software management tools.
Our facilities feature in-house testing laboratories equipped with over 150 measurement and test instruments. Over 20 specialized quality control inspectors monitor assembly procedures through PLM, BI, ERP, and MES software pipelines, verifying performance criteria before final export packaging.
A deep breakdown of the Acereare low-voltage product range designed for power distribution protection.
Our ARW1 Series Air Circuit Breakers are designed for distribution networks operating at 50Hz, rated voltages up to 690V, and currents between 400A and 6300A. Built with high-precision selective microprocessors, the ARW1 ensures system reliability by preventing cascade failures. The unit includes open industrial communication protocols to enable four remote functions: remote sensing, remote adjustment, remote control, and remote signaling, linking directly to SCADA and central control automation systems.
Designed for projects requiring precise calibration, the ARM3E series provides adjustable settings for short-time delay, long-time delay, and instantaneous trip parameters. Integrating LSIG (Long, Short, Instantaneous, Ground fault) protection, it serves as a robust defense for critical manufacturing lines where standard thermal-magnetic breakers might not offer the required precision.
Featuring a built-in LCD interface, the ARM6 series provides real-time current measurements and diagnostics. It supports remote operations, allowing operators to monitor trip states and adjust settings remotely. This helps minimize maintenance times in automated plants and hazardous processing zones.

Our breakers are engineered to meet specific localized environmental conditions and challenging industrial environments.
Standard breakers can fail in sub-zero environments due to grease congealing and structural component brittleness. We construct our cold-resistant breakers using specialized low-temperature alloys and low-viscosity synthetic lubricants. These designs are certified to operate reliably down to -40°C for wind turbine control loops and outdoor mining installations.
Humid, salt-heavy marine air can accelerate terminal corrosion and lead to electrical faults. Our marine-grade breakers feature thickened anti-corrosion platings on all copper and steel conductors. They undergo 72-hour complete machine salt spray testing to ensure reliable operation on offshore rigs, commercial ports, and ships.
Above altitudes of 2000m, the thinner air reduces dielectric cooling capacity and voltage withstand ratings. To prevent premature arcing or insulation breakdown, we design customized high-altitude circuit breakers with expanded internal air clearances and adjusted thermal trip curves, maintaining system safety across high plateaus.
Modern commercial buildings demand dense panel designs and highly reliable protection systems. Our compact Molded Case Circuit Breakers deliver high breaking capacities in space-saving enclosures. This simplifies layout planning for distribution boards in malls, office high-rises, and hospital standby power systems.
Environments like metal refineries, paper mills, and desert solar farms often experience elevated ambient temperatures. We manufacture our breakers with flame-retardant, high-temperature composite shells and temperature-compensated trip units. These systems are validated in our constant-temperature testing chambers at 55°C to prevent nuisance tripping.
Future power distribution relies on real-time data monitoring and remote management. Our smart circuit breakers feature integrated current sensors, voltage transformers, and network processors. They measure voltage, current, power factor, and harmonic distortion directly, communicating data back to SCADA platforms via Modbus RTU or Ethernet protocols.
Industrial procurement relies on stable production and on-time shipping. By operating two dedicated components and assembly factories in China, Acereare Electric maintains close control over manufacturing schedules. We integrate advanced ERP and U8 management software to coordinate tooling, metal stamping, arc-chute production, and final testing. This localized integration helps us manage raw material costs and ensures stable product availability even during periods of high global demand.
OEM & ODM Capabilities: From modifying trip curves and developing custom molds to full certification testing (CE, CCC, IEC), our R&D team can customize solutions to match your local market requirements.
For custom production runs, we provide product visualization models, run rapid 3D prototype verification, and assist in arranging regional certification testing. This collaborative development model helps our international clients launch new products quickly and cost-effectively.

We structure our commercial operations into three clear, client-focused service divisions:
Common questions from plant engineers, electrical contractors, and procurement departments.
At altitudes above 2000 meters, air density drops, which reduces heat dissipation efficiency and the insulation strength of the air. This requires thermal derating (the breaker runs hotter) and dielectric derating (reduced peak voltage capacity). For such cases, our engineers adjust current ratings and dielectric margins using standard derating tables to ensure safe, stable performance.
Icu (Ultimate Short-Circuit Breaking Capacity) is the maximum fault current a breaker can interrupt safely without suffering catastrophic failure, though the breaker may require replacement afterward.
Ics (Service Short-Circuit Breaking Capacity) is the level of fault current the breaker can interrupt and still remain operational. For high-reliability environments, look for breakers where Ics = 100% Icu, indicating the unit can handle repeated fault interruptions without loss of protection performance.
Thermal-Magnetic Trip Units utilize bimetallic strips and electromagnets. They are robust, cost-effective, and ideal for basic commercial distribution networks.
Electronic Trip Units (LSIG) use current transformers and microprocessors to monitor current values. They offer adjustable delay times and precise tripping limits for Overload (L), Short-time delay (S), Instantaneous (I), and Ground fault (G) scenarios. Choose LSIG systems for complex industrial grids, motors, and automation systems that require precise coordination to avoid nuisance tripping.
We replace standard mechanical grease with synthetic low-viscosity industrial lubricants that resist freezing. The physical linkages are constructed with treated alloys that prevent cold-brittleness. All internal electronic components are coated in protective insulation to prevent moisture condensation and electrical leakage during rapid temperature shifts.
Our circuit breakers conform to the international standard IEC/EN 60947-2. They carry CE, CCC, and ISO9001 certifications. For specific national projects or unique grid requirements, we can supply test reports and coordinate with third-party testing labs to acquire local certifications.
