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

The motor protection circuit breaker from Yueqing Huilong offers comprehensive protection for electric motors, combining overload, short-circuit, and phase-failure protection in a single device. This breaker features a bimetallic thermal element for overload protection and a magnetic coil for short-circuit protection, with adjustable current settings (0.1-63A) to match motor requirements. It includes phase-failure detection, triggering a trip within 2 seconds of detecting an unbalanced phase, preventing motor damage. The breaker’s compact design (DIN rail-mount, 17.5-55mm widths) saves panel space, while transparent covers allow visual inspection of internal components. Meeting IEC 60947-2 standards, it is ideal for motors in pumps, compressors, and machine tools, ensuring safe and reliable operation.
