Explore our industrial-grade, certified circuit breakers designed to withstand rigorous thermal, voltage, and environmental demands.
Acereare Electric, founded in 2015, possesses "RuiRui Electric" and "KeRui Electric" as two wholly-owned subsidiaries. As a professional, state-of-the-art original equipment manufacturer (OEM) and original design manufacturer (ODM), Acereare integrates research and development, high-volume production, and comprehensive sales channels under one global umbrella. We specialize in Molded Case Circuit Breakers (MCCB), Air Circuit Breakers (ACB), and premium component engineering.
With over 20 years of craftsmanship inherited by two generations, our manufacturing roots runs deep. Officially registered in 2015 to coordinate international growth, our factories rank among the top tier of ODM/OEM electrical infrastructure suppliers in China. We pride ourselves on offering complete vertical integration—from stamping metal parts to complete device calibration and testing.
Integrated supply agreements with nearly 100 high-end domestic and overseas strategic partners testify to our reputation as an industry-trusted partner.
Acereare leverages scale, automation, and world-class engineering to provide low-voltage switchgear that sets the industry standard.
Modern electrical infrastructure demands resilience. Our circuit protection engineering caters to global climates, high-altitude installations, and precision digital networks.
Standard distribution equipment fails in extreme cold due to mechanical seizing or fracturing of standard plastics. Acereare engineers utilize special low-temperature lubricants and high-impact structural polymers. Every low-temp custom device undergoes certification protocols down to -40°C, verifying switch speeds and physical trip characteristics are within limits.
Designed for coastal areas and dock applications. Our components are subjected to rigorous salt spray testing (48 hours for sub-assemblies and 72 hours for complete structural casings). This process ensures that internal copper busbars, moving contacts, and spring components resist galvanic oxidation, reducing failure rates in marine environments.
Operating in thin air changes thermal dissipation dynamics and insulation properties. We provide detailed high-altitude electrical coefficient adjustment tables (derating curves). This documentation ensures electrical engineers size MCCBs and ACBs safely for setups exceeding standard operating limits.
In desert environments and sealed enclosures, internal heat buildup can trigger false thermal tripping. Acereare employs high-temp insulation coatings, enhanced copper conductor dimensions, and verifies stability through environmental chamber testing at +55°C to avoid nuisance tripping.
Our flagship ARM3E and electronic series feature microprocessor-controlled trip units (LSIG options). By incorporating built-in metering, edge logic calculation, and modbus/ethernet open communication protocols, these components easily integrate with remote SCADA networks, providing utility status telemetry.
Solar inverter installations push voltages to 1000VAC, 1140VAC, and 1500VDC. Our specialty photovoltaic solar MCCBs feature optimized contact geometry and magnetic blowout structures to extinguish high-energy DC and AC electric arcs safely.
A reliable supplier must offer more than low pricing. We deliver consistency through complete component supply chain control.
Many circuit breaker assemblers buy external parts, leading to varying tolerances and quality inconsistency. Acereare controls its supply chain, producing our own critical structural parts like MCCB stampings and moving copper contacts. Our one-stop setup uses six core processing techniques and run 10+ manual and automated assembly lines.
We run over 50 R&D projects annually. Our design team uses 3D modeling and structural simulation software to design parts, mold forms, and complete chassis layouts. Production operations are integrated through PLM, ERP, BI, and MES management systems to ensure traceability from incoming copper feed stock to finished circuit breakers.

Acereare products undergo independent lab testing to meet CE, CCC, CB, ISO9001, and environmental safety regulations.
The low-voltage circuit protection industry is transitioning from purely thermal-magnetic tripping mechanisms to digital, connected solid-state switchgear. Key factors driving this shift include the expansion of decentralized solar installations, large-scale battery storage networks, and the expansion of high-density data centers.
Unlike Alternating Current (AC), which naturally passes through a zero-voltage point, Direct Current (DC) generates high-energy arcs that do not self-extinguish easily. As solar installations transition from 1000VDC to 1500VDC, circuit breakers require specialized arc chutes, strong permanent magnets to guide the arc, and wider contact gaps. Acereare's R&D efforts are focused on developing optimized arc-extinguishing chambers to handle these challenges.
Traditional mechanical contacts physically separate to break a circuit, producing a minor arc that causes eventual wear. Next-generation hybrid circuit breakers combine fast mechanical actuators with semiconductor switches. This design allows them to isolate fault currents in microseconds, virtually eliminating the arc and extending contact service life.
Modern smart grids depend on remote monitoring and data collection. Our smart circuit breakers feature integrated current transformers and microprocessors to monitor system parameters. By tracking factors like contact wear, operating cycles, and temperature changes, the system can predict maintenance needs before an unexpected failure occurs.
