Eaton / Moeller Series
MCCB, UL/CSA, Cable Terminals, Handle sold separately
The Klockner Moeller NZM6B-63 series molded case circuit breakers are designed for demanding industrial and commercial power distribution systems. Built on a 63A frame, these breakers support a wide range of trip unit configurations—including fixed and adjustable thermal-magnetic (ZM6, ZM6A) and electronic (ZM6-OBI) options—allowing precise protection from 1.2A up to 2000A. Available variants include standard, North American (CNA), and U.S. (NA) regional configurations.
Each unit comes with field-wiring terminals for both line and load sides and is designed to operate at voltages up to 690V AC. Select models feature adjustable instantaneous and long-time trip functions to enhance coordination and selectivity in complex systems. These breakers conform to global safety standards and are UL 489 and CSA C22.2 No. 5.1 certified. Operating handles are supplied separately to allow flexibility in mounting and user interface options. With robust protection and wide configurability, the NZM6B-63 series supports applications across motor protection, feeder circuits, and main switchboards.
