HAIPART: Comprehensive Solutions for Low-Voltage Electrical Circuit Breaker Parts
HAIPART, a professional manufacturer of low-voltage electrical circuit breaker parts, offers six categories of high-quality core components: MCB, MCCB, RCCB, RCBO, SPD, and ACB. Precision manufacturing and rigorous quality control ensure product reliability. MCB/MCCB assemblies provide overload and short-circuit protection through electromagnetic and thermal tripping mechanisms, suitable for residential, commercial, and industrial power distribution systems. RCCB/RCBO components detect leakage current or integrate multiple protection functions, providing personal safety protection for homes, hospitals, and other locations. SPD accessories suppress transient overvoltages, protecting sensitive electronic equipment such as data centers and communication base stations. ACB components, as high-current frame circuit breakers, feature intelligent tripping and remote control functions, suitable for medium- and high-voltage scenarios such as substations and rail transit. HAIPART leverages its strengths in material innovation, intelligent integration, and environmentally friendly design, continuously developing products that meet international standards, providing customized solutions for traditional power, new energy, and emerging market sectors, and jointly building an efficient and intelligent electrical ecosystem.
