140MG Motor Protection Circuit Breakers

Our Bulletin 140MG Motor Protection Circuit Breakers can provide a disconnecting means for motor branch circuit, branch-circuit and short-circuit magnetic protection, overload thermal protection, and manual switching. We offer devices rated from 25...150 A to meet your particular needs. Our factory-installed internal accessories make installation and wiring easy. In North America, electrical codes require that an individual Motor Branch Circuit be protected by a UL/CSA Listed Fuse, Circuit Breaker, or Self-protected Combination Motor Controller.
