Motor Circuit Breaker for Overload & Short Circuit Protection | UL/CE Certified

Yueqing Huilong’s motor protection breaker is a critical safety device designed to protect electric motors from overloads, short circuits, and phase-related faults. This breaker combines thermal-magnetic tripping elements, with thermal protection for gradual overloads and magnetic protection for instantaneous short circuits. It features adjustable current settings (0.1-100A), allowing customization for various motor ratings, and trip classes (10, 10A, 20) to match motor starting characteristics. The breaker’s DIN rail-mount design (modular widths) integrates easily into control panels, while visual trip indicators and manual reset buttons simplify maintenance. Constructed with impact-resistant materials (UL94 V-0), it withstands harsh industrial environments, ensuring reliable motor protection in manufacturing, processing, and logistics systems.
