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

The motor circuit protector from Yueqing Huilong is a specialized device designed to protect electric motors from overloads, short circuits, and phase-related faults, ensuring reliable operation and extended motor life. This protector combines thermal-magnetic tripping technology, with thermal elements responding to overloads and magnetic elements to short circuits, offering dual-layer protection. It features adjustable current settings (0.1-100A) to match motor ratings and trip classes (10, 10A, 20) to accommodate different starting characteristics. The protector’s DIN rail-mount design (modular widths) fits easily in control panels, while visual trip indicators and manual reset buttons simplify maintenance. Constructed with flame-retardant materials (UL94 V-0), it withstands harsh conditions, making it essential for motors in manufacturing, logistics, and process industries.
