Discover our leading range of circuit protection devices designed for automation, solar systems, and heavy industrial distribution.
Founded in 2015, Acereare Electric operates two wholly-owned subsidiaries: RuiRui Electric and KeRui Electric. As a premier original equipment manufacturer (OEM/ODM), we integrate advanced research and development, smart manufacturing, and dynamic customer relations networks to deliver global-standard Molded Case Circuit Breakers (MCCB), Air Circuit Breakers (ACB), and structural electrical parts.
We build upon a 20-year history of craftsmanship inherited across generations, translating standard circuit management tools into heavy-duty safety infrastructure. In terms of both production capability and technological innovation, our facilities rank among the highest-performing ODM platforms in China, delivering electrical component reliability globally.
An authoritative analysis of standard constraints, application profiles, and structural safety parameters in contemporary grid setups.
In modern industrial systems, low-voltage distribution platforms demand high reliability and minimal downtime. Sourcing managers and electrical engineers require deep-level technical accountability from manufacturers. Factors like short-circuit breaking capacity (Icu/Ics), coordination, operational mechanism longevity, and environment tolerance (especially in high-altitude, maritime, or high-temperature environments) dictate system performance.
Chinese manufacturers have transitioned from producing simple replicas to developing highly engineered, proprietary low-voltage circuit breakers. Acereare Electric operates at the forefront of this trend, producing circuit breakers equipped with electronic trip units (LSIG) that offer precise adjustments for overload long time delay, short-circuit short time delay, short-circuit instantaneous protection, and ground fault protection.
The global push for solar energy systems has created new requirements for circuit isolation and protection components. Photovoltaic (PV) installations operate under sustained direct current (DC) or elevated AC voltages (often 800VAC, 1000VAC, or 1140VAC). Regular circuit breakers cannot extinguish the high-energy arcs that occur at these voltage levels.
To address this need, Acereare Electric has engineered specialized solar MCCBs (such as our 3-pole 400A AC800V/1000V/1140V models). These devices feature advanced arc-chute assemblies, specialized silver alloy contacts, and heat-resistant compound cases to safely extinguish electrical arcs and protect solar inverters, combiners, and battery storage banks.
A reliable circuit breaker relies on the quality of its internal metal stamping and molding parts. Substandard contacts, bimetals, or structural plastics result in premature wear, thermal runaway, and mechanical failures.
By producing our own structural parts (including precision metal stamping and DMC/BMC molding), Acereare Electric guarantees consistency at every step. This vertical integration allows us to customize components for international clients and ensures that every MCCB body and moving contact meets strict mechanical and electrical tolerances.
Reliable performance under harsh physical conditions.
Designed with specialized low-temperature lubricants and thickened structural coatings. Every unit is certified via low-temperature chamber analysis (-40°C) to prevent freezing of mechanical linkages and guarantee reliable tripping during emergencies.
Engineered for maritime applications, ports, and offshore systems. Our circuit breakers undergo rigorous salt spray chamber validation (72 hours for finished assemblies, 48 hours for core metal sub-components) to prevent oxidation.
For installations above 2000m, air density changes affect heat dissipation and insulation properties. We provide high-altitude correction tables to adjust parameters for optimal, derated system performance.
Integrated solutions for residential electrical panels. Featuring sensitive magnetic-thermal trip components that react instantly to short circuits and overloads, shielding consumer electronics and appliances from damage.
Utilizes thermal-resistant polymers and heat-reflective surface barriers. Internal copper and iron mechanisms are treated to resist corrosion and moisture, validated in a constant temperature room at 55°C.
A smart energy monitoring system offering edge computing, metering, and telemetry. Fully compatible with Modbus and RS485 communication protocols, allowing integration with smart grid software.
How Acereare Electric prepares for the next generation of power distribution systems.
We are phasing out standard halogenated resins, replacing them with recyclable thermoplastic polymers. This reduction in environmental impact meets RoHS and REACH standards for international infrastructure projects.
With utility solar installations moving toward 1500VDC architectures, our R&D team is developing specialized DC circuit breakers designed for large-scale energy storage arrays.
By leveraging semiconductor materials, our next-generation solid-state circuit breakers will achieve microsecond tripping times, virtually eliminating mechanical contact wear.
Reliable production systems, robust software integration, and customized solutions.
One-stop production incorporating six core processing techniques. We run high-precision stamping, welding, assembly, and testing platforms across 10 manual and automated production lines.
Over 50 dedicated R&D engineers, each with 5+ years of experience, design custom mechanical modules, molds, and finished assemblies using 3D modeling and analysis software.
We operate two factories dedicated to both complete assemblies and individual components. Operations are managed using integrated ERP and U8 software for end-to-end efficiency.
Our quality control program utilizes PLM, BI, ERP, and MES software. Our in-house testing lab employs 150+ specialized test instruments and a team of 20+ QC inspectors.

Frequently asked questions from engineers, procurement managers, and systems integrators.
Molded Case Circuit Breakers (MCCB) protect circuits from overload, short-circuits, and ground faults in current ranges from 15A up to 3200A. Air Circuit Breakers (ACB) are typically installed in main distribution switchboards to handle currents from 400A up to 6300A, using open-air arc extinction mechanisms for larger, high-fault current applications.
At elevations above 2000m, thinner air reduces both cooling efficiency and dielectric strength. To compensate, circuit breakers must be derated by reducing operational current limits and adjusting insulation assumptions. Acereare Electric provides detailed high-altitude derating charts to help maintain reliable operation up to 5000m.
No. Direct current arcs are harder to extinguish than alternating current arcs because they do not cross zero current. Standard AC MCCBs will fail under DC loads. Solar installations require specialized DC or high-voltage AC solar MCCBs designed to manage elevated system voltages up to 1140VAC or 1500VDC.
We manufacture key metal parts and components in-house using high-purity silver-alloy contacts and copper stampings. These parts undergo regular chemical, structural, and mechanical wear checks in our quality control laboratory before moving to final assembly.
Yes, we provide full ODM services. We customize dimensions, mounting options, and trip tolerances, and provide international certification support (including IEC and CE testing) to meet your local grid regulations.
