Explore our engineering-grade heavy-duty circuit protection solutions, manufactured to strict international testing standards.
Founded in 2015, Acereare Electric operates as an industry-leading OEM and ODM powerhouse, integrating two wholly-owned subsidiaries: "RuiRui Electric" and "KeRui Electric".
Building upon 20+ years of technical heritage and craftsmanship passed down across two generations, our operation is based in China's low-voltage electrical capital. Over the decades, we have established long-term strategic supply relationships with nearly 100 high-end domestic and international clients, engineering high-precision Molded Case Circuit Breakers (MCCB), Air Circuit Breakers (ACB), and premium mechanical contact components.
Meeting the strict parameters and performance needs of industrial, commercial, and utility buyers worldwide.
Global procurement teams prioritize strict compliance with IEC 60947-2 standards, demanding verified breaking capacities (Icu/Ics) to secure distribution networks against major thermal and magnetic anomalies.
Renewable projects require specialized high-voltage DC and AC molded case circuit breakers capable of operating reliably at 800VAC, 1000VAC, and 1140VAC to handle solar inverter and battery storage configurations.
Global electrical brands need strong OEM/ODM partners with vertically integrated production lines, raw material control (such as silvered moving contacts), and automated product assembly lines to secure regional markets.
"For manual circuit breakers, global engineering and procurement leaders require not just components, but certified, long-term operational guarantees. The ability to manually disconnect grid zones during unexpected maintenance while relying on precise mechanical and electronic trip triggers is crucial for ensuring worker safety and protecting high-value grid investments."
Our circuit breakers are designed and tested to deliver consistent, certified performance in the most demanding real-world environments.
Built with low-temperature resistant structural resins and high-grade specialty lubricants. Key mechanical linkages feature thickened anti-corrosive coatings, supported by verified laboratory testing down to -40°C.
Capable of withstanding harsh maritime salt air. We perform 72-hour salt spray testing on complete assemblies and 48-hour testing on sub-components to ensure long-term, stable operation in coastal docks, offshore sites, and marine vessel power rooms.
Designed for installations located above 2000 meters. We provide dedicated high-altitude derating coefficients and charts, adjusting voltage and current specifications to offset thin air and lower dielectric cooling efficiency.
Widely utilized in high-density residential load centers. Our space-saving MCCB designs protect high-end appliances, smart automation systems, and HVAC units from sudden overload and short-circuit faults.
Engineered using heat-resistant polymer housings. The inner metallic linkages are treated to resist moisture, oxidation, and corrosion under continuous thermal load. Tested and rated inside our custom 55°C environmental chambers.
Equipped with built-in metering chips, communication interfaces, and microprocessor controllers. Supports real-time voltage and current monitoring, power consumption analytics, and smart grid automation protocols.
A comprehensive overview of our current low-voltage switchgear portfolio, designed to handle power requirements from 63A to 6300A.
The ARW1 series intelligent air circuit breakers are engineered for high-power distribution grids operating at 50Hz, with rated voltages up to 690V and currents ranging from 400A up to 6300A. They deliver precise selective protection to maintain grid stability and prevent localized blackouts. Crucially, they feature an open digital communication interface that supports telemetry, remote adjustment, remote control, and real-time signalling (the "Four Remote" features) to integrate with SCADA and industrial automation networks.
