HAIPART – Reliable Core Assemblies for Low-Voltage Electrical Equipment

HAIPART, a professional assembly manufacturer in the low-voltage electrical industry, specializes in R&D and production of high-reliability core assemblies—including magnetic trip units, thermal trip units, operating mechanisms, contact assemblies and connector modules. Magnetic trip units quickly cut off circuits via electromagnetic induction to protect equipment from overloads or short circuits; thermal trip units trigger tripping through the thermal effect of bimetallic strips to prevent overload operation; operating mechanisms ensure precise switching and reset of circuit breakers and contactors; contact assemblies control current on-off with high conductivity and wear resistance for long-term stability; connector modules enable rapid modular docking to improve installation and maintenance efficiency. These flexibly combinable assemblies are widely used in molded case circuit breakers, air circuit breakers, contactors and relays, delivering safe and efficient solutions for power distribution, industrial control and automation. With innovative design and strict quality control, HAIPART supports customers in creating stable and reliable electrical products.
