Acereare Electric, founded in 2015, stands as a premier Original Equipment Manufacturer (OEM) and Original Design Manufacturer (ODM) specializing in high-performance Molded Case Circuit Breakers (MCCB), Air Circuit Breakers (ACB), and premium electrical accessories. With our core operating entities "RuiRui Electric" and "KeRui Electric" functioning as wholly-owned subsidiaries, we maintain complete control over the entire production cycle—from basic stamping moulds to complex microprocessor trip units.
Our operational history is backed by a multigenerational electrical engineering lineage spanning over two decades. This deep-domain expertise has enabled us to design advanced thermal-magnetic trip units, electronic trip systems, and specialized high-voltage circuit protective devices. Today, Acereare is recognized globally as a high-technology enterprise, servicing grid operators, renewable energy installers, and industrial developers with dependable safety solutions.
The modern power distribution paradigm is undergoing structural transformations. With the rapid expansion of solar photovoltaic farms, utility-scale battery energy storage systems (BESS), and electric vehicle charging infrastructures, circuit protection must adapt to higher operating voltages and variable load profiles. Thermal magnetic MCCBs act as the front-line defense mechanism in these systems, preventing thermal overloads and short-circuit faults that could compromise multi-million dollar investments.
Acereare Electric develops MCCB topologies designed for high-voltage DC and AC applications, such as our Solar Type Molded Case Circuit Breakers rated for 800VAC up to 1140VAC. By implementing advanced arc-chute designs and optimization of contacts, we resolve the severe electrical arcing common in high-voltage DC environments, ensuring safe interruption at high currents.
Optimized breakers for 1000V/1500V DC and high-voltage AC networks, preventing thermal runaway in solar combiner boxes, inverters, and battery storage subsystems.
Designed for motor protection and switchboard integration, offering high short-circuit breaking capacities (Icu) up to 200kA at 400V/690V to handle large fault currents.
Integration of intelligent microprocessors (LSIG trip units) with communication capabilities, facilitating real-time monitoring and automation in modern smart grids.
Our facilities feature six different high-precision manufacturing processes. We utilize automated stamping, plastic molding, spot welding, and final breaker assembly across 10 manual and automated assembly lines.
Over 50 dedicated R&D engineers, each holding 5+ years of low-voltage switchgear engineering experience. We complete 50+ research projects annually using advanced 3D mold-flow analysis and simulation software.
Operating two production plants—one dedicated to metal stamping and plastic molding components, and another focused on terminal breaker calibration and assembly. Integrated using advanced ERP and U8 business systems.
Equipped with an internal testing laboratory featuring 150+ testing instruments, run by 20+ QC inspectors. Operations are managed using PLM, MES, and BI software to track calibration data for every individual circuit breaker.
Standard off-the-shelf components can fail in demanding environments. Acereare Electric develops and rates its products for specialized applications, ensuring reliable protection under high temperatures, sub-zero conditions, and high altitudes.
Low Temp
We utilize specialized, low-temperature resistant thermoplastic polymers and high-viscosity, low-temperature lubricants. All mechanisms are treated with thick anti-oxidizing coatings. Supported by comprehensive testing down to -40°C, these breakers operate reliably in sub-zero regions without material embrittlement.
Marine
Designed for docks, shipboard power, and coastal wind farms. We conduct 72-hour salt spray testing on complete breakers and 48-hour testing on components. Copper and steel parts are treated to prevent oxidation, ensuring mechanical integrity in saline air.
Altitude
Lower air density at high altitudes reduces heat dissipation and dielectric insulation. We apply altitude derating factors in accordance with IEC 60947-2, modifying clearances and thermal trip settings to ensure continuous protection up to 5000 meters.
Residential
Optimized for sub-distribution panels, residential complexes, and commercial properties. These breakers feature compact dimensions, high electrical durability, and simple DIN-rail or mounting plate systems to simplify installation and maintenance.
High Temp
Engineered for high-temperature zones like desert installations and hot industrial plants. Internals feature heat-resistant insulators, and all copper conductors are nickel- or tin-plated. Standard ratings are verified through 55°C thermal chamber testing.
Smart Grid
Equipped with built-in current transformers and microprocessors, these advanced breakers support high-accuracy power metering, real-time status reporting, and communication protocols, enabling edge-computing integration within smart energy networks.
We work with international brands, distributors, and engineering houses to deliver customized circuit protection solutions. We manage the development process from initial design to validation and mass production.
Our OEM and ODM workflows are designed to support rapid product development and brand customization:
All manufacturing facilities are ISO 9001 certified. Our circuit breakers undergo testing to meet international safety standards, including CE, CCC, KEMA, and CB.
Acereare Electric's research focuses on the digitization and control of electrical safety devices. We are developing solutions that incorporate IoT connectivity and predictive maintenance diagnostics directly into MCCB architectures. Future updates to our product line will include:
Thermal-magnetic MCCBs utilize a bi-metallic element for overload protection (thermal trip) and an electromagnetic coil for instantaneous short-circuit protection. They are reliable, robust, and cost-effective. Electronic trip units (such as our ARM3E and ARM5E series with LSIG protection) use microprocessor-controlled current sensors. This allows for adjustments to the Long-time overload, Short-time delay, Instantaneous short-circuit, and Ground fault settings to match specific coordination needs.
At altitudes above 2000 meters, the thinner air reduces cooling efficiency and dielectric strength. To compensate, breakers must be derated for both operational voltage and rated current. For example, at high altitudes, the heat dissipation of the bi-metallic strip is reduced, and the dielectric strength of the air gap changes, requiring engineers to consult a high-altitude derating table to verify safety margins.
Yes. Our ARM6DC series photovoltaic DC MCCBs are designed for solar applications, with voltage ratings of 700V, 1000V, and 1500V DC. They feature optimized contact structures and specialized arc-extinguishing chambers to handle the high electrical arcs that occur when interrupting high-voltage DC currents.
We conduct environmental chamber testing, including 72-hour salt spray testing on complete breakers and 48-hour testing on sub-assemblies. All exposed steel and copper components are plated or treated to prevent corrosion and oxidation from salt and moisture, ensuring reliable mechanical action.
Yes, we provide full OEM/ODM support, including custom plastic molding, laser branding, and customized packaging. Our internal R&D team can develop custom components and assist with international safety certifications for authorized trademarks.
