High-performance molded case circuit breakers, adjustable trip mechanisms, and automated controls engineered for global energy networks.
Founded in 2015, Acereare Electric is a premier original equipment manufacturer (OEM) and original design manufacturer (ODM) in the low-voltage power distribution sector. With two wholly-owned subsidiaries—RuiRui Electric and KeRui Electric—we manage integrated production, processing, and distribution networks. We specialize in designing and manufacturing high-performance Molded Case Circuit Breakers (MCCB), Air Circuit Breakers (ACB), and premium-grade components.
Our craftsmanship roots trace back over 20 years, representing two generations of engineering heritage in low-voltage electrical apparatus design. Since registering formally in 2015, we have built a modern production facility in China, ranking among the top-tier domestic manufacturers in output capacity, product reliability, and product quality validation.
We deliver reliable low-voltage engineering services, blending materials science with custom electrical configurations.
One-stop processing with six distinct production techniques, high-precision automated tooling, and over 10 manual and automated assembly lines.
50+ experienced mechanical and electrical engineers executing 50+ custom design projects annually using advanced 3D mold-flow and thermal analysis software.
Dual factories running unified ERP and U8 software systems, ensuring dynamic scheduling, material planning, and consistent lead times.
In-house testing facility equipped with over 150 instruments and 20+ QC inspectors, managing lifecycle tracking through integrated PLM, BI, and MES platforms.
Maximizing production precision through automation and end-to-end component traceability.
By producing critical internal copper and silver-alloy contacts in-house, we control contact resistance and thermal characteristics, reducing dependencies on external parts suppliers. Our metal stamping and molding technologies protect against raw material delays.
We synchronize our component manufacturing and final assembly systems via localized ERP databases. From copper stamping to coil winding and magnetic trip calibration, every manufacturing step is recorded to support high quality-control standards.
Every MCCB and ACB undergoes automated testing for contact resistance, thermal-magnetic calibration, and dielectric strength. This process filters out deviations before packaging, maintaining low return rates for global distributors.
Engineering next-generation low-voltage circuit breakers to support smart grids and distributed energy systems.
Modern homes and commercial buildings demand real-time energy insights. We are developing smart, IoT-enabled circuit breakers that use Modbus, Wi-Fi, and Zigbee protocols to transmit current, voltage, and diagnostic data to home automation systems.
To support microgrids and renewable energy systems, our technical roadmap focuses on solid-state circuit breaking technologies. These electronic systems interrupt overloads in microseconds, providing fast protection for delicate electronics.
We use recyclable thermosetting plastics and lead-free contact materials in our products. Our engineering processes prioritize high reliability while minimizing environmental impact, aligning with RoHS and REACH standards.
Our circuit breakers are designed and tested to operate reliably across a wide range of industrial environments.
Engineered with specialized low-temperature lubricants and reinforced polycarbonate housings. Third-party laboratories have verified reliable operation down to -40°C, making these units suitable for outdoor switchgear in cold climates.
Designed with anti-corrosive coatings on magnetic trip units and copper conductors. Our products are tested for up to 72 hours (assembled unit) and 48 hours (sub-assemblies) to ensure long-term performance in marine and coastal installations.
For installations above 2000 meters, we apply certified de-rating coefficients to account for thinner air and reduced dielectric cooling. Our engineering tables help ensure electrical safety at high elevations.
Our MCCB and MCB solutions protect household appliances from overloads and short circuits. These compact systems fit easily into standard consumer units, providing reliable overcurrent protection.
Our components are built with high-temperature resistant composites and thermal isolation layers. We conduct performance tests in our 55°C environmental chambers to verify stable trip points and prevent nuisance tripping in hot climates.
Equipped with integrated current transformers and communication modules, these breakers support real-time current tracking, voltage measurement, and data transmission to energy management systems.
Meeting international electrical standards to support direct integration into global distribution systems.
Acereare circuit breakers are manufactured in accordance with major international standards. Our quality control processes ensure compliance with IEC/EN 60947-2 (for industrial applications) and IEC/EN 60898-1 (for residential use). We provide complete design documentation, electrical schematics, and test reports to simplify local regulatory approvals.
