High-performance Circuit Breakers and OEM accessories designed for global distribution and mission-critical installations.
Modern electrical systems operate in environments that demand absolute reliability. The basic mechanism of thermal magnetic protection remains a cornerstone of safety in low-voltage electrical distribution. Thermal protection utilizes a bimetallic strip that deflects during sustained overcurrents, ensuring protection against prolonged thermal overload. Simultaneously, the magnetic element acts instantaneously against short-circuit faults via an electromagnetic coil, isolating hazardous circuits in milliseconds.
As global grids integrate complex renewable energy systems, variable loads, and smart metering tech, thermal magnetic circuit breakers (MCCBs) have evolved. Today's devices feature higher breaking capacities (up to 200kA), structural modularity, and environment-resistant components designed to handle everything from solar PV overvoltages to mechanical vibrations in heavy industrial sectors.
Acereare Electric: Delivering reliable circuit breakers through decades of structural mastery and technological innovation.
Founded in 2015, Acereare Electric has established itself as an original manufacturer, integrating R&D, structural design, and vertical manufacturing of molded case circuit breakers (MCCB), air circuit breakers (ACB), and premium component accessories. With two wholly-owned subsidiaries, RuiRui Electric and KeRui Electric, we inherit over 20 years of craftsmanship passed down across two generations.
Our operation is rooted in the complete manufacturing ecosystem. Unlike simple assembly factories, we produce critical internal components in-house, such as our silvered moving contacts and custom busbar stampings, ensuring consistent quality control and pricing advantages across our entire product range.
We deliver structural designs, high precision processing, and tested solutions to secure your electrical systems.
A true one-stop service powered by six processing techniques. We operate high-precision fabrication gear, custom testing instruments, and over 10 manual and automated assembly lines to meet high production volumes.
Over 50 R&D engineers with 5+ years of industry experience. Using advanced 3D engineering software, our team produces 50+ innovative protection designs and mechanical patents annually.
We own two dedicated domestic factories to scale the production of internal components and final builds. Integration via ERP and U8 management systems guarantees timely deliveries.
A multi-step quality control inspection using 150+ sets of laboratory instruments and 20+ expert quality engineers. We enforce strict compliance through PLM, BI, ERP, and MES tracing software.
We engineer modular drawout bases, interlocking structures, and functional accessories. This facilitates simpler installations, easier field upgrades, and reduces maintenance down-times.
Our solutions conform to international testing requirements. We support global compliance needs by offering complete documentation and test reports for key global markets.
Acereare MCCBs deliver consistent protection in challenging conditions, from freezing high-altitude sites to hot, salty coastal areas.
Constructed using low-temperature resistant composite plastics and specialized mechanical lubricants. Thickened anti-freezing coatings allow operation down to -40°C, backed by laboratory testing.
Ideal for ports and marine power setups. Built to withstand salty marine environments, our complete units pass 72-hour salt spray tests (and 48 hours for core sub-assemblies) to ensure lasting operation.
At altitudes above 2000m, lower air density impacts heat dissipation and dielectric insulation. We apply calculated derating profiles to keep high-altitude installations safe and efficient.
Highly flexible layouts that protect household and light commercial circuits against overloads and faults, delivering long-term switching life and reliable safety.
Engineered using heat-resistant thermal plastics, anti-corrosive metals, and insulated controller elements. Verified in our 55°C testing chambers to ensure steady operation in hot climates.
Integrates protection, real-time energy metering, edge analytics, and remote communications (Modbus/RS485), providing data infrastructure for smart grids.
Tested and certified electrical protection products designed to meet demanding global regulatory and safety frameworks.
Flexible design, fast-prototyping, and certified testing options engineered to bring your custom configurations to market quickly.
Our standardized project workflow ensures clear communications, exact design alignment, and reliable deliveries.
Detailed technical answers to common queries regarding thermal magnetic operation, ambient limits, and manufacturing specifications.
From modular drawer bases to adjustable trip units, discover our range of low-voltage component designs.
