Miniature Circuit Breakers (MCB)
Shop miniature circuit breakers for control panels, DIN-rail assemblies, distribution boards, machinery, lighting, and branch-circuit applications.
Selection factors include UL 489 or UL 1077 application, voltage, poles, amp rating, interrupting rating, B/C/D trip curve, terminal arrangement, supplementary contacts, and mounting dimensions. An MCB with the same amp rating is not automatically an approved replacement.
