Explore our premium range of Moulded Case Circuit Breakers (MCCB), Air Circuit Breakers (ACB), and structural components designed for high-breaking capacities and extreme environmental conditions.
Founded officially in 2015, Acereare Electric operates two wholly-owned subsidiaries: "RuiRui Electric" and "KeRui Electric". Building on over 20 years of low-voltage electrical component craftsmanship inherited across two generations, we are a professional original equipment manufacturer integrating state-of-the-art research, precision production, and global sales.
Our advanced factories rank among the top tier of ODM/OEM circuit breaker manufacturers in China. Combining localized expertise with structural design methodologies, we specialize in high-reliability Moulded Case Circuit Breakers (MCCB 150 Ampere frame models and beyond), complex Air Circuit Breakers (ACB), and structural copper assemblies that form the backbone of safe electrical distribution grids.
As the worldwide energy sector transitions to low-carbon, smart distribution topologies, electrical protection demands have grown exponentially.
Modern PV solar installations generate operating voltages up to 1000V/1140V. Our thermal-magnetic and electronic MCCBs protect critical solar combiner boxes and inverter stations from sudden DC system surges, minimizing operational downtime.
Decentralized networks demand edge telemetry. Advanced electronic trip unit (LSIG) technologies provide Modbus/Ethernet protocols for real-time electrical parameter tracking, transforming classical circuit breakers into data nodes.
With massive AI computing facilities and modern gigafactories, power density demands reliable short-circuit breaking capacities up to 200kA. Precision engineering in arc-chute design ensures immediate thermal dispersion under high transient loads.
Providing custom electrical designs, reliable lead times, and global validation compliance.
One-stop processing using six kinds of specialized technical processes, high-precision automated manufacturing equipment, and over 10 manual and automated assembly lines.
Over 50 R&D engineers with extensive multi-year design experience, utilizing advanced 3D CAE/CAD system software for rapid custom stamping, mold creation, and component mechanics modeling.
Operating dual manufacturing plants for components and final assembly. Management processes are seamlessly integrated via modern ERP and U8 systems for transparent lead times.
Equipped with internal laboratories housing over 150 sets of specialized test instruments. Quality is controlled via enterprise PLM, BI, ERP, and MES software integrations.
Our circuit breakers are built to withstand extreme environmental challenges, providing reliable operation in demanding conditions.
Using specialized low-temperature resistant lubrication oils, custom-blended polymeric structural shells, and thick exterior zinc-nickel plating, our circuit breakers carry official test reports down to -40°C.
We conduct rigorous salt spray chamber tests: 72 hours for fully assembled units and 48 hours for semi-finished components. These breakers resist humid ocean mist, protecting motors and switchboards on coastal docks.
When operating in high-altitude environments, thin air affects dielectric strength and convective cooling. We apply precise electrical derating calculation tables to adapt performance safely.
Our MCCB series are widely deployed in commercial distributions and large-scale residential complexes. They safeguard HVAC installations, lighting panels, and large motors against sudden overcurrents.
Featuring high-temperature thermal insulators and copper busbars coated with specialized protective films, our units undergo constant-temperature testing inside dedicated 55°C chambers.
Supporting Modbus, GPRS, and local RS485 communication lines, these intelligent units enable remote switching, edge energy-efficiency calculations, and high-precision system metering.
All Acereare Electric manufacturing facilities operate under ISO 9001 and ISO 14001, with standard certifications verifying compliance.

Understanding how material sciences and software algorithms shape the future of electrical circuit protection.
Traditional mechanical breakers rely on physical separation of copper contacts, causing electric arcs that require extinguishment. The future lies in semiconductor-based solid-state circuit breakers, which can isolate faults within microseconds without producing an arc.
By integrating temperature, current, and magnetic flux sensors directly onto the connection plates, our upcoming smart MCCB generations use edge-AI processing to predict contact wear and mechanical failure before they occur.
Reducing carbon footprints requires clean engineering. We are actively researching bio-based, self-extinguishing polymers and halogen-free housing materials that maintain high dielectric strength while remaining recyclable.
Direct technical answers addressing the selection, thermal limits, and application profiles of molded case circuit breakers.
Silvering deposits a highly conductive, oxidation-resistant layer onto the moving contacts. This lowers contact resistance, minimizes thermal buildup under continuous load, and prevents contact welding during short-circuit events, extending mechanical and electrical life.
At altitudes above 2000 meters, low air density reduces heat dissipation and the dielectric strength of air. To prevent thermal runaway or arc flashover, parameters like rated current and operating voltage are adjusted using standard altitude correction coefficients.
Thermal-magnetic units use a bimetallic strip for overload and an electromagnet for short-circuit protection. Electronic (LSIG) units use current transformers and microprocessors to provide adjustable settings for Overload (L), Short-time delay (S), Instantaneous (I), and Ground fault (G) protection.
Yes. Our breakers use low-temperature oils and custom materials for -40°C environments, and undergo constant-temperature testing at 55°C to ensure thermal stability in high-temperature applications.
