Explore our engineering breakthroughs. High circuit breaking capacity, smart LCD monitoring, and customized operating mechanisms engineered for continuous, zero-failure operations.
Founded officially in 2015, Acereare Electric is built upon a legacy of electrical craftsmanship inherited over two generations. Incorporating two wholly-owned subsidiaries, "RuiRui Electric" and "KeRui Electric", we operate as a premium-grade original design manufacturer (ODM) and original equipment manufacturer (OEM).
We are specialized in molded case circuit breakers (MCCB), air circuit breakers (ACB), and vital electronic components. Backed by state-of-the-art labs and manufacturing ecosystems, our processes integrate 6 main types of processing techniques, operating with more than 10 manual and automated assembly lines to ensure maximum accuracy and safety in distribution grids.
We balance manufacturing capacity with design flexibility, offering robust global delivery and strict Quality Assurance protocols.
One-stop production combining high-precision equipment, advanced testing instruments, and over 10 high-output assembly lines.
50+ senior R&D engineers utilizing advanced 3D component and mold design systems. Over 50 active annual R&D projects.
Two modernized factories managing end-to-end component fabrication and system assembly via ERP and U8 software integrations.
Comprehensive in-house test labs with 150+ instrumentation sets. Multi-step checks controlled via PLM, BI, and MES software.
Understanding Direct Current Interruption Physics, Global Industry Standards, and Grid Security Architecture.
In power distribution, direct current (DC) circuit protection is more complex than alternating current (AC). AC naturally passes through a zero-current point twice per cycle. During a short circuit, this zero-crossing helps clear the electrical arc in the circuit breaker. Conversely, DC has a flat, constant current signature. When contacts separate under load, the arc is continuous and does not self-extinguish. Circuit breakers must actively force the arc to zero.
To interrupt high-voltage DC (up to 1000VDC or 1500VDC), DC MCCBs use specialized components, including permanent magnets, directional magnetic blowouts, and extended, multi-slotted arc chutes. These designs pull the arc away from the contact surfaces and divide it into series fractions, cooling and extinguishing it. Directional installation is critical; reversed polarity can blow the arc out of the chamber rather than into the arc chute, leading to equipment failure.
Global decarbonization has increased demand for DC circuit protection. Key industries include:
Industrial installations expose circuit protection components to harsh environments. Acereare Electric builds circuit breakers engineered to withstand these conditions:
We tailor electrical protection mechanisms to operate reliably in challenging industrial settings worldwide.
Our circuit breakers feature low-temperature lubricants and reinforced structural materials to prevent mechanical jamming in cold climates, verified down to -40°C.
Built to resist humid marine environments. Standard units pass 72-hour salt spray testing, protecting shipboard systems, docks, and coastal projects.
Adjusted for altitudes exceeding 2000m. We calibrate dielectric strength and thermal dissipation levels to match low-pressure atmospheric conditions.
Protects home appliances and building circuits from short-circuits and overloads, providing a reliable distribution foundation for residential panels.
Equipped with thermal barriers and moisture-resistant metals. We test under sustained +55°C conditions to prevent false trips in hot industrial settings.
