Explore our engineering-focused lineup of high-precision MCCBs, heavy-duty ACBs, and stamping parts engineered for harsh environments and industrial grid infrastructure.
Acereare Electric was founded in 2015 and comprises two wholly-owned subsidiaries: "RuiRui Electric" and "KeRui Electric". Specializing in Molded Case Circuit Breakers (MCCB), Air Circuit Breakers (ACB), and premium structural metal components, we inherit over 20 years of technical craftsmanship passed down across two generations.
With an unwavering focus on raw material integrity, electrical endurance, and structural design, we rank among the top-tier ODM/OEM manufacturing powerhouses in China, driving safety and power stability across global industries.
How we are engineering smart, high-breaking-capacity breaker ecosystems to align with the digitalization of energy grids.
Next-generation electronic trip units integrated with Microprocessor Control Units (MCUs). Our ARM3E and ARM6 series support real-time current harmonic analysis, edge computing for fault predictions, and digital parameter setting interface, transitioning breakers from simple passive protection devices to critical smart grid data nodes.
Driven by the massive expansion of solar PV systems and commercial battery energy storage system (BESS) grids, our technical path is pushing current boundaries to achieve rated insulation voltages of up to 1000V AC / 1500V DC. Specialized arc extinguishing materials and dual magnetic drive fields ensure rapid clearing times during massive overload currents.
Full physical and digital integration with industrial fieldbus networks (Modbus RTU, Profibus-DP, and Ethernet TCP/IP). Facility engineers can monitor contact wear index, mechanical cycle life, and thermal dissipation thresholds remotely, significantly reducing downtime and emergency plant failures.
Providing custom, high-durability solutions backed by intensive R&D, vertical component integration, and advanced ERP logistics.
One-stop processing involving six distinct advanced production techniques. High-precision stamping, tool and die fabrication, automated component assembly lines, and calibrated electrical test benches guarantee consistent dimensional accuracy and thermal calibration tolerance.
Our team of over 50 veteran electrical engineers designs, simulates, and models molded structures, contact profiles, and trip mechanisms in fully integrated 3D environments. We deliver over 50 custom projects annually to meet special industrial and utility requirements.
Operating two modern domestic factories allows for the seamless internal provisioning of raw metal stampings, plastic housings, and assembled trip mechanisms. Integrated enterprise resource planning (ERP) systems sync our logistics pipelines for on-time export delivery.
Equipped with a certified physical testing laboratory, our quality processes check mechanical cycle limits, thermal tolerance values, and dielectric isolation parameters. Over 150 dedicated test instruments track raw components to final assembly lots using PLM/MES tracking software.
Unifying computerized production scheduling, real-time material traceability, and automated machinery to maintain cost competitiveness.
Unlike secondary assembly plants, Acereare Electric operates integrated stamping and copper-machining facilities. Because we manufacture the critical internal stamping parts and connection plates in-house, we control raw material purity, prevent oxidation, and reduce assembly tolerances. Dynamic manufacturing planning software schedules metal forming, silver contact welding, and housing injection molding simultaneously, shortening production lead times by up to 35% compared to typical OEMs.
By implementing computerized quality controls at every station, we maintain complete control over raw material grades, chemical composition, and dimension consistency across our entire product catalog.
From micro-molded components to drawer-type high-current switchgear, we manufacture custom products configured to withstand harsh industrial and commercial applications.
The ARW1 series air circuit breaker is designed for low-voltage AC 50Hz/60Hz distribution systems with a rated operating voltage of 690V and below, handling rated currents from 400A up to 6300A. The integrated micro-processing unit provides high-accuracy selective protection against overloads, short-circuits, ground faults, and phase imbalances. It features built-in Modbus communication, allowing real-time monitoring, adjustment, and control commands from central supervisory control systems (SCADA).

Find technical answers regarding breaking capacities, high-altitude adjustments, material compliance, and OEM services.
$I_{cu}$ (Rated Ultimate Short-Circuit Breaking Capacity) specifies the maximum fault current a breaker can safely interrupt, though it may require replacement afterward. $I_{cs}$ (Rated Service Short-Circuit Breaking Capacity) indicates the fault current level the breaker can interrupt and still return to normal service. Our high-breaking-capacity series typically feature $I_{cs} = 100\% I_{cu}$ to ensure reliable operation after fault clearance.
Higher altitudes have lower air density, which reduces both convective cooling and the dielectric isolation properties of the air. To prevent overheating and accidental arc flashovers, we apply derating coefficients to the rated operational current ($I_e$) and rated operational voltage ($U_e$). Our engineering team provides custom altitude derating calculations for projects in mountainous areas.
For operations in extremely cold climates, we utilize low-temperature lubricants that resist thickening and housings made from high-impact structural plastics. These units are tested to operate down to -40°C, helping prevent mechanical binding or cracking when resetting in sub-zero environments.
Our smart circuit breakers feature integrated current transformers (CTs) and voltage sensing circuits connected to a microprocessor unit. This design measures voltage, current, power factor, and harmonic distortion in real time. It communicates this telemetry over Modbus or Profibus to SCADA systems, enabling remote energy monitoring and predictive contact wear analysis.
Yes. We operate dedicated metal stamping and tooling workshops. We manufacture custom copper connection plates, fixed contacts, and structural brackets to meet specific mounting dimensions and current loading requirements. This helps ensure consistent assembly tolerances and reliable electrical contact performance.
Depending on part complexity, initial mold design, flow analysis, and physical prototype fabrication takes 30 to 45 days. Once prototypes are approved through our testing lab, production setup takes approximately 15 to 20 days. Development fees may be refunded once mass production orders meet contract thresholds.
