USED KLOCKNER/MOELLER NZM6B/ZM6-63-CNA

The Klockner/Moeller NZM6B/ZM6-63-CNA (catalog designation NZM6B-63/ZM6-63) is a 3-pole molded case circuit breaker (MCCB) built on a 63A frame and equipped with the ZM6-63 adjustable thermal-magnetic trip module. It provides adjustable thermal overload protection from 40–63A and adjustable magnetic (instantaneous) short-circuit protection from 400–800A, making it well-suited for motor branch circuit protection, feeder circuits, and main switchboard applications. Conforming to IEC/EN 60947-2, UL 489, and CSA C22.2 No. 5.1, this breaker is designed for demanding industrial environments including mining, pulp & paper, food processing, nuclear power, and marine applications. Currently manufactured by Eaton Corporation (formerly Klockner/Moeller).
