Three-pole molded case circuit breaker with thermal-magnetic trip unit. Bimetallic thermal element offers inverse time overload protection, magnetic component triggers instantaneous trip for short circuit fault. It cuts off faulty circuit rapidly to safeguard cables, transformers and downstream loads, and supports auxiliary contact for remote status feedback.

Certification: CE, IEC

Insulating molded housing, bimetallic thermal trip element, magnetic release, contact assembly, arc extinguishing chamber and operating mechanism. Common faults: contact overheating, abnormal tripping, arc chamber carbon accumulation and trip element aging.
