Molded Case Circuit Breakers (MCCB)

About Molded Case Circuit Breakers (MCCB)

Molded Case Circuit Breakers (MCCBs) provide short-circuit and overload protection for low-voltage feeders, motor circuits, and distribution panels, commonly rated from 15A to 2500A. Common sub-types include thermal-magnetic, electronic (solid-state) trip, adjustable instantaneous, motor-protection, and current-limiting units in fixed or drawout mounting styles.
