Engineered for high performance, reliability, and precision power distribution control.
Founded officially in 2015, Acereare Electric has grown into a major standard-setter in high-performance circuit protection. Operating through two key wholly-owned manufacturing subsidiaries—RuiRui Electric and KeRui Electric—we represent a multi-generational legacy of over 20 years in custom craftsmanship, electrical design, and precision metallurgy.
We are a premier, comprehensive OEM and ODM manufacturer that integrates research and development, smart manufacturing, global distribution, and complete technical support. Our products specialize in Air Circuit Breakers (ACB), Molded Case Circuit Breakers (MCCB), and their fundamental metal components, accessories, and automated mechanisms.
Today, our factories rank among the top ODM partners in China, supplying major global power brands, utility companies, industrial project contractors, and regional switchgear assembly plants. We operate on a foundational promise: delivering robust electrical protection that performs flawlessly under the most extreme operating environments.
Why industrial procurement teams choose Acereare Electric as their primary overseas partner.
We do not just assemble breakers; we manufacture the critical internal stamping parts, connection plates, and busbars. This deep vertical integration guarantees rigorous quality control and insulates our customers from supply chain delays.
Our dedicated team of 50+ engineers works in 3D parts modeling, mold development, and custom mechanical designs. We manage over 50 new R&D projects every year, keeping our designs aligned with international standards.
We run integrated factory management via PLM, ERP (U8), BI, and MES platforms. This coordinates ordering, engineering designs, precision stamping, robotic inspection, and shipping tracking to minimize human error.
Helping our partners secure target markets with premium product standards and reliable delivery timelines.
We offer a true one-stop service powered by six specialized processing technologies, high-precision stamping equipment, automated assembly setups, and more than 10 manual and robotic assembly lines.
Our 50+ engineers bring over 5 years of industry experience. Using 3D software for molds, components, and complete assemblies, they prototype and design customized electrical components quickly.
With two modern manufacturing facilities, we expand components and finished assembly capacity simultaneously. By coordinating logistics and production via unified ERP databases, we ensure on-time delivery.
We use over 150 testing instruments, supported by a specialized internal testing lab and over 20 full-time inspectors. This setup monitors every stage of production through PLM, ERP, and MES software.
The ARW1 series intelligent Air Circuit Breaker is engineered for AC 50Hz/60Hz power distribution networks with rated operational voltages up to 690V and rated current ranges from 400A up to 6300A. Built specifically for critical infrastructure projects, commercial grids, and heavy industrial facilities, these ACBs provide high-precision protection and selective circuit safety, ensuring stable power delivery.
Equipped with a smart microcomputer controller, the ARW1 offers high selective coordination, preventing wide-scale power interruptions. It includes an open communication interface that supports standard protocols like Modbus, enabling remote monitoring and control. This system provides "remote sensing," "remote adjustment," "remote control," and "remote signaling," meeting the integration needs of automated control rooms and smart grid setups.
Our MCCB product portfolio spans multiple series designed for distinct applications:
Specific circuit breaker configurations tailored to withstand harsh operational conditions across diverse global projects.
Designed with specialized low-temperature resistant plastics, low-viscosity mechanical lubricants, and thickened metal coatings. All products undergo testing in our environmental chamber to secure a verified -40°C performance certificate, making them ideal for sub-zero installations.
Engineered for seaside docks, marine vessels, and offshore wind platforms. Our components undergo 72-hour salt spray testing for finished assemblies and 48-hour testing for semi-finished parts. This level of protection prevents rust and decay in high-humidity, high-salinity air.
In high-altitude areas with thin air, heat dissipation drops and insulation strength decreases. We provide specialized high-altitude derating tables and adjusted thermal-magnetic designs to ensure reliable operation above 2000 meters.
Using thermal insulation coatings on electronic controllers, along with anti-corrosive copper and iron parts, these breakers are designed for high-heat industrial plants. We verify high-temperature derating and mechanical life inside our 55°C constant-temperature rooms.
Integrates communication, high-precision power metering, safety protection, and edge computing. These breakers support real-time current and voltage monitoring while communicating over RS485, Modbus, or Ethernet protocols to connect directly with smart grids.
Highly flexible, compact, and designed for distribution boards in residential projects. They provide critical protection for downstream household appliances and equipment against overloads and short circuits.
We work closely with global electrical brands, switchgear builders, and industrial suppliers to customize circuit protection products for regional markets.
Building your brand equity requires high-quality, distinctive products. We provide custom brand markings, unique outer housing shapes, custom-designed packaging box sets, and tailored technical catalog files to set your business apart from competitors.
Leverage our advanced factory capacity as your own manufacturing facility. We offer customized mechanical mold designs, customized electronic trip mechanism programming, and help you secure local technical approvals (such as CE, CB, SEMKO, or KEMA) with refundable development fee structures.
Work directly with our engineering team to design custom circuit breaker systems from the ground up. We handle everything from the initial mechanical drawings and structural simulations to final lab testing and mass production.
Acereare Electric maintains rigorous international compliance, certified by top global testing bodies.
