Explore our certified components and high-voltage breaker systems engineered for industrial reliability.
Acereare Electric, founded in 2015, stands as a premier design and manufacturing powerhouse. Working through our two wholly-owned subsidiaries, RuiRui Electric and KeRui Electric, we provide strategic ODM and OEM production workflows for nearly 100 high-end domestic and global brands.
Rooted in over 20 years of electrical craftsmanship passed down through two generations, we have engineered deep domain expertise in Smart Molded Case Circuit Breakers (MCCB), Intelligent Air Circuit Breakers (ACB), and precision metal components. Today, we stand as one of China's most trusted manufacturers, leveraging smart factory practices to secure power systems worldwide.
Moving beyond basic overcurrent trip units into the era of edge computing, local telemetry, and IoT network integration.
Standard thermal-magnetic MCCBs rely on bimetallic strips and electromagnetic coils to offer overcurrent and short-circuit protection. While reliable, these mechanisms lack precision and cannot adapt to dynamically changing electrical loads. Our next-generation smart breakers, such as the ARM3E series, utilize digital electronic trip units with adjustable LSIG parameters:
By integrating high-contrast LCD modules directly onto the front face of components like the ARM6Z-630-3300 LCD MCCB, operators gain real-time insight into phase-by-phase currents, fault diagnostic archives, and contact wear indicators. Under the hood, built-in Modbus-RTU, Profibus, or Ethernet communication gateways transmit telemetry to remote SCADA platforms or building management systems. With remote motorized operating mechanisms (e.g., ARM5 Series Electric Mechanism), breakers can be toggled via software control centers, significantly minimizing maintenance downtime and improving safety margins for operators.
Our upcoming product lines incorporate IoT edge computing architectures. These units monitor high-frequency electrical signatures to perform predictive maintenance audits, identify harmonics, analyze voltage sags, and output real-time carbon footprints. This turns the circuit breaker from a simple reactive safety switch into an active diagnostic node for advanced commercial power distribution networks.

Our smart circuit breakers are designed and tested to perform reliably in demanding, harsh environmental conditions.
Built with low-temperature resistant structural resins and specialized low-viscosity mechanical lubricants. Reinforced surface plating on core mechanisms prevents embrittlement and preserves structural integrity in sub-zero environments, backed by certified performance reports down to -40°C.
Designed for ports, dockyards, and offshore wind platforms. Our components undergo 72-hour salt spray testing for complete units and 48-hour testing for individual metal sub-assemblies, providing reliable corrosion protection against humid, saline air.
In thinner high-altitude air, dielectric strength and heat dissipation capacity drop. To maintain reliability, we apply specific derating adjustment factors for operating voltage and thermal ratings when breakers are deployed above 2,000 meters.
Compact form factors designed for home automation systems and consumer distribution boards. These units offer protection against circuit overload and short-circuit faults, while maintaining clean installation aesthetics and reliable operation.
Engineered for hot climates and high-temperature industrial settings. Electronic trip controllers feature built-in thermal insulation shields, and all critical current-carrying conductors are treated with corrosion-resistant finishes tested inside our 55°C climate chambers.
Our smart circuit breakers go beyond simple overcurrent protection. They include integrated current sensors and voltage pick-offs that enable high-precision energy metering, remote power quality analysis, and real-time edge processing for modern smart grids.

Helping procurement teams and field engineers select, configure, and maintain smart electrical components.
Electronic trip breakers (such as our ARM3E series) use microprocessor controllers to measure current real-time, providing more precise, repeatable, and customizable trip curves compared to thermal-magnetic models. They allow you to configure independent LSIG settings (Long, Short, Instantaneous, and Ground Fault delays) to build a selective coordination layout. This confines electrical faults to specific branch sub-panels and prevents general facility outages.
At high altitudes, thin air reduces both dielectric strength and heat dissipation efficiency. To keep temperatures stable and prevent dielectric breakdown, you should apply a high-altitude derating adjustment to your circuit breaker. For installations above 2,000 meters, refer to our specific derating tables to lower the maximum continuous current capacity and rated insulation voltage specs appropriately.
For seaside and marine installations, we construct breakers using corrosion-resistant platings and high-grade copper busbars. We run rigorous salt spray testing (72-hour exposure for fully assembled units and 48-hour testing for individual metal sub-assemblies) to ensure our MCCBs can handle humid, salty air and maintain performance in marine switchboards and shipyard power systems.
Our smart circuit breakers (like the ARM6Z series) support Modbus-RTU, Profibus, and Ethernet communications. They can transmit key telemetry data—including phase currents, system voltages, power factors, and diagnostic logs—directly to SCADA, industrial PLCs, and cloud platforms for unified power quality monitoring.
For custom ODM projects, we charge an initial development fee to cover the design and manufacturing of the necessary injection molds and stamping dies. Once your orders reach our agreed-upon volume milestones, these development fees are fully refunded, helping you manage initial tooling costs.
We maintain full control over quality by fabricating our core connection plates, contacts, and copper busbars in-house. Our quality assurance team uses computerized optical sorting, hardness testing, and automated micro-ohmmeter calibration to verify that every component matches our strict electrical conductivity and dimensional tolerance standards.
