Structural Features
This series of circuit breakers consists of a plastic housing, overcurrent trip unit, operating mechanism, contacts, and arc extinguishing system. The housing is made of high-strength, highly flame-retardant plastic.
Multi-pole circuit breakers are assembled from multiple single poles. The trip units are connected by a linkage rod, and the handle is integrated with a linkage cover, ensuring consistency in switching operations at each stage.
