Explore our leading industrial circuit breakers engineered for high-performance and strict safety metrics.
Founded in 2015, Acereare Electric is a powerhouse in Low Voltage distribution engineering, comprising two wholly-owned manufacturing subsidiaries: RuiRui Electric and KeRui Electric.
We are a professional original manufacturer integrating R&D, production, and sales. We specialize in Molded Case Circuit Breakers (MCCB), Air Circuit Breakers (ACB), and structural copper components. Inheriting over 20 years of craftsmanship from two generations of engineering leaders, our factory group stands as a Top-tier well-known ODM manufacturer in China, delivering solid technical expertise, product reliability, and high-performance operations.
In modern industrial facilities, switchgear manufacturers, and global infrastructure projects, procuring reliable low-voltage components is critical to grid reliability. Sourcing Molded Case Circuit Breakers (MCCB) requires a balance of high performance, environmental compliance, and cost-efficiency. Global commercial and industrial buyers focus on selecting components with specific electrical profiles, long electrical lifespans, and certificates that streamline global exports.
High-voltage solar PV systems, critical data centers, and heavy-duty manufacturing centers operate under demanding power requirements. To ensure system coordination, engineers must evaluate three primary parameters:
| Parameter | ARM1 Series (Standard) | ARXM3 Series (Performance) | ARM5HU Series (High Voltage PV) |
|---|---|---|---|
| Rated Voltage (Ue) | AC 400V/690V | AC 400V/690V | AC 800V/1000V/1140V |
| Rated Current (In) | 16A - 1250A | 63A - 125A | 100A - 630A |
| Breaking Capacity (Icu) | 35kA - 85kA | 50kA - 100kA | 35kA - 50kA (at high Ue) |
| Trip Unit Type | Thermal-Magnetic | Thermal-Magnetic / Electronic | Specialized PV Magnetic |
Global supply networks face several challenges, including copper commodity price volatility, compliance with international standards (such as IEC/EN 60947-2), and shipping logistics. Industrial buyers need partners who can stabilize prices and offer flexible OEM/ODM contract terms. Working with direct manufacturers like Acereare Electric simplifies procurement, ensuring fast engineering response, customizable packaging, and international compliance certification.
We deliver reliable quality and high performance through complete in-house manufacturing, R&D, and quality inspection.
One-Stop Service utilizing six core processing technologies, high-precision automated assembly lines, and over 10 active production lines.
Over 50 R&D engineers with 5+ years of experience. We provide 3D CAD modeling, component structural simulations, and custom performance design.
Operating two manufacturing facilities to scale up component stamping and final assemblies. Supported by ERP and U8 logistics management.
Rigorous in-house laboratory testing with over 150 instruments. Backed by 20+ QC inspectors using PLM, MES, and BI tracking software.
Acereare Electric designs custom circuit breakers for specialized industrial environments, from high altitude to smart grids.
We use low-temperature resistant bimetals and specialized mechanical lubrication. Tested and verified for reliable operation at temperatures down to -40℃.
Specifically designed for docks and offshore installations. Complete units undergo a 72-hour salt spray test, and key components undergo a 48-hour test, protecting contacts against humid, salty maritime environments.
For installations above 2000m. We adjust voltage and current ratings based on a high-altitude derating table to compensate for thinner air and reduced thermal dissipation.
Protects household appliances and HVAC systems against short-circuits and overloads. Highly compact designs simplify installation in standard distribution boards.
Constructed with high-temp heat-resistant housings and thermally insulated internal barriers. Tested to operate stably in constant-temperature test environments up to 55℃.
Supports edge computing, real-time power metering, and remote RS485/Modbus communication. Enables smart grid integration, remote control, and predictive maintenance diagnostics.
For primary power distribution boards and high-capacity switchgear panels, the ARW1 Series Intelligent Air Circuit Breaker is designed to protect low-voltage distribution systems. Operating at 50Hz, with rated voltages up to 690V and currents from 400A to 6300A, the ARW1 ACB provides reliable protection and high short-circuit withstand capabilities (Icw).
The ARW1 ACB features electronic trip units that allow precise protection settings, supporting selective coordination between upstream breakers and downstream MCCBs. This prevents cascading trips, isolating faults to the affected sub-circuit and keeping the rest of the facility powered.
Its open communication interface supports Modbus-RTU, Profibus, and DeviceNet protocols, enabling four key functions for automation and control centers:
Interrupting high currents produces intense electrical arcs that can wear down contacts. Our ARW1 and ARM5 series feature arc-chutes designed to split and cool arcs. Standard copper contact carriers are faced with silver alloy inserts, providing high electrical conductivity and resistance to contact welding during fault conditions.
Acereare Electric products are rigorously tested to meet global electrical safety, quality, and environmental regulations.
