Eaton / Moeller Series
MCCB, thermal-magnetic/electronic trip, adjustable, UL/CSA
The Klockner Moeller NZM6B-160 series molded case circuit breakers are designed for high-capacity industrial applications requiring flexible and reliable circuit protection. Built on a 160A frame, these breakers are equipped with a range of thermal-magnetic (ZM6A) and advanced electronic (ZM6-OBI) trip units, offering adjustable protection settings up to 2000A. Rated for operation up to 690V AC, these breakers are available in multiple regional configurations including global (no suffix), North America (CNA), and U.S. (NA). Select models support extended trip calibration ranges such as 800A or 2000A, enhancing selectivity and coordination. All models feature bolt-on terminals for line and load connections and require a separately ordered handle for operation. Certified to UL 489 and CSA C22.2 No. 5.1 standards, the NZM6B-160 series is ideal for protecting feeders, switchboards, and high-load circuits in mission-critical environments.
