Explore our high-performance circuit protection devices manufactured in our state-of-the-art facilities in China, designed to meet rigorous global standards.
Founded in 2015, Acereare Electric serves as a benchmark of engineering precision and high-capacity manufacturing in Wenzhou, China. With two wholly-owned subsidiaries—RuiRui Electric and KeRui Electric—our enterprise inherits over 20 years of technical expertise passed down through two generations.
As a leading original equipment manufacturer (OEM) and original design manufacturer (ODM), we specialize in the design, development, and massive fabrication of Molded Case Circuit Breakers (MCCB), Air Circuit Breakers (ACB), and vital electrical components. Our strategic integration of R&D and advanced testing laboratories ranks us among the elite low-voltage electrical product ODM factories in China.
Air Circuit Breakers (ACBs) serve as the vital protection shield for low-voltage power distribution networks across massive industrial plants, high-rise commercial complexes, data centers, and clean energy utility nodes. Globally, the demand for high-reliability circuit protection is accelerating, driven by the rapid transition to electrification, smart grids, and localized renewable power installations.
Modern industrial architectures demand circuit breakers that do not simply trip upon overload but actively coordinate fault protection to ensure continuous service operation. As global power demand skyrockets, ACBs are expected to handle higher rated operational currents (often up to 6300A) and massive short-circuit breaking capacities ($I_{cu}$), typically ranging from 50kA to over 120kA under 400V/690V environments.
Manufacturers in China have moved past low-cost assembly to establish highly integrated R&D centers, matching international standards like IEC 60947-2, UL 489, and CE. The global supply chain relies on Chinese ACB factories not only for finished units but also for heavy metal stamping, silver alloy contact systems, and advanced electronic trip units (microcontrollers).
The technology roadmap for next-generation Air Circuit Breakers centers on intelligence, modularity, and environmental sustainability. China's top factories are shifting towards digitizing the physical trip unit through IoT-enabled microprocessors.
Modern ACBs feature intelligent trip units (microcontrollers) offering real-time current, voltage, power factor, and harmonics calculation. Integration with Modbus, Profibus, or Ethernet protocols allows seamless connection to centralized SCADA systems.
Developing complex dielectric insulation structures to maintain performance in low-pressure, high-altitude regions above 2000 meters. Advanced thermal management prevents tripping drift due to external temperature spikes.
Transitioning from traditional hazardous substances to RoHS-compliant materials. Designing recycle-friendly modular plastic shells and using lead-free silver alloy contacts for safe arc extinguishing.
Why international utility companies, heavy industrial plants, and smart grid switchboard builders partner with Acereare Electric.
We offer a true one-stop production pipeline. Utilizing six key manufacturing techniques alongside high-precision machinery, we operate 10+ manual and automated assembly lines capable of fabricating components and complete units.
Our R&D team consists of 50+ dedicated engineers, each bringing over 5 years of domain experience. We design critical components and structures in 3D CAD, delivering over 50 custom projects annually.
With two modern, specialized factories producing both inner components and final assemblies, we coordinate our supply chains through ERP and U8 software, ensuring transparent scheduling and on-time international delivery.
Operating our own test laboratory, we inspect parts and assemblies using over 150 dedicated testing instruments and 20+ QC inspectors. The entire lifecycle is monitored via integrated PLM, BI, ERP, and MES software.
Our circuit breakers are built and certified to function across extreme scenarios, securing high performance where standard breakers fail.
We deploy specialized low-temperature resistant structural polymers and low-viscosity mechanical oils. Copper conductors and contacts undergo thick plating treatments. Every unit is certified by our -40°C low-temperature environmental laboratory test report.
Built for maritime and offshore applications. We conduct 72-hour salt spray testing on complete machines and 48-hour testing on sub-assemblies. This enables our MCCB and ACB systems to resist marine salt spray and prevent mechanical corrosion.
At high altitudes, thin air reduces heat dissipation and dielectric insulation. We provide high-altitude derating models, adjusting clearing times, insulation distances, and current thresholds to guarantee stable protection without false trips.
Designed for terminal distribution boxes. These products feature compact structures and dynamic thermal trip curves, protecting household appliances and commercial building lines from overloads and short circuit damages.
To prevent thermal runaway in high-temp steel plants or desert solar stations, we construct breakers with heat-resistant materials. The controller board is coated with a thermal insulation layer, validated by continuous aging tests in our 55°C chambers.
Our smart breakers feature integrated current transformers and high-precision digital metering engines. Supporting edge computing and bidirectional communication protocols, they serve as core sensors for smart grids.
The ARW1 series intelligent Air Circuit Breaker (ACB) is engineered to protect critical infrastructure in low-voltage distribution networks. Applicable to AC 50Hz networks with a rated operational voltage ($U_e$) up to 690V and a wide rated current range from 400A to 6300A, it provides high-precision fault protection.
With integrated digital microprocessors, the ARW1 offers high selective protection, improving system coordination and power supply reliability. It is equipped with open industrial communication protocols, enabling four distinct remote capabilities:
This advanced remote feature set ensures seamless integration with automated distribution networks and energy management systems.
Whether building a new electrical brand or expanding an existing system, our factories supply components and custom packaging solutions.
Every single circuit breaker leaving our assembly lines is subject to extensive dielectric testing, calibration, and structural checks to meet global standards.
