Explore our premium grade moving contacts, thermal-magnetic MCCBs, drawer-type Air Circuit Breakers (ACB), and mechanical interlock systems engineered for grid safety.
Two decades of technical heritage, providing premium circuit protection equipment worldwide.
Founded in 2015, Acereare Electric has established itself as an industry-leading manufacturer with two wholly-owned subsidiaries: RuiRui Electric and KeRui Electric. Inheriting over 20 years of craftsmanship passed down through two generations, the group ranks among the top well-known ODM manufacturers in China in terms of experience, technology accumulation, and full-scale factory capacity.
We specialize in the research, development, and production of Molded Case Circuit Breakers (MCCB), Air Circuit Breakers (ACB), and essential structural components. We utilize advanced ERP & U8 platforms to coordinate design, supply chains, and manufacturing departments across two modern industrial factories.
The modern global landscape is experiencing unprecedented electrification demands, driven by digital data center expansion, grid integration of utility-scale renewable energy systems (photovoltaic arrays and wind power generation), and automated heavy manufacturing lines. In these complex electrical systems, minor faults like short circuits, transient overloads, or ground faults can result in multi-million dollar equipment damages and operational downtimes. As a result, sourcing from a verified wholesale breaker catalogue supplier has transitioned from simple procurement to a strategic operation focused on system safety and electrical selectivity.
Acereare Electric addresses these macro-industry challenges by manufacturing molded case circuit breakers and air circuit breakers with high breaking capacities (up to 6300A in ACB units, and customizable thermal-magnetic or electronic MCCB units). Operating with both mechanical reliability and digital precision, our equipment safeguards power distribution structures under rigorous mechanical stress and varying climatic factors.
To support high-current distributions, the ARW1 Series Intelligent Air Circuit Breakers (ACB) operate at rated voltages up to 690V and currents ranging from 400A to 6300A. A key feature is their high-precision selective protection trip unit. It operates with a dynamic communication interface that enables "Four Remote" configurations: remote sensing, remote adjustment, remote control, and remote signaling. This structure meets the modern requirements of automated control centers and smart microgrid systems.
For MCCBs, including the ARM3E, ARM5, and ARM6 Series, we utilize adjustable electronic and thermal-magnetic trip units (with LSIG capabilities). These enable precise setting of protection thresholds for long-time overload, short-time delay short circuit, instantaneous short circuit, and ground faults. This adaptability ensures that upstream breakers do not trip unnecessarily, minimizing downtime across localized grid sections.
A premier supplier providing robust manufacturing, R&D, and complete supply chain traceability.
Our facility provides a one-stop manufacturing process covering six distinct processing techniques. Using high-precision production machinery and calibration systems, we operate more than 10 manual and automated lines to deliver high product yields.
Our team includes over 50 R&D engineers, each bringing over 5 years of industry experience. They utilize 3D modeling software for structural elements, mold design, and complete unit assembly, launching over 50 new R&D projects annually.
We operate two production facilities to split component fabrication from final assembly. Production flow, inventory, and order fulfillment are integrated via centralized ERP and U8 software to coordinate departmental logistics.
We employ a multi-step quality control protocol utilizing an on-site testing laboratory. With over 150 dedicated testing instruments and 20 inspectors, our quality assurance systems are integrated via advanced PLM, BI, ERP, and MES software platforms to monitor every stage of production.

We are a dedicated circuit breaker manufacturer with more than 10 years of automated production experience. Acereare Electric maintains strategic supply agreements with over 100 industrial clients worldwide. We focus on customer value, product performance, and robust electrical systems.
Acereare circuit breakers are certified under major domestic and international safety standards.
Traditional thermal-magnetic protection systems are transitioning toward digital, programmable breaker architectures. To support this shift, Acereare Electric's technology roadmap focuses on incorporating microprocessors and IoT communication cards directly into the MCCB and ACB product lines. These smart circuit breakers do more than isolate overload conditions; they act as distributed monitoring nodes across the electrical infrastructure.
By measuring voltage phases, load profiles, harmonic distortions, and operational temperatures at the contact interfaces, our smart breakers send real-time data to factory management interfaces. Using this information, system operators can predict grid failures and conduct preventative maintenance before costly outages occur. These capabilities help industrial facilities reduce operating costs and optimize energy distribution.
