The Eaton Industries MCCB Circuit-breaker NZM2 is a 4-pole device with a rated current of 200A. It operates at a nominal voltage of 690V with a nominal tripping capacity (Icu) at 400 150kA. Its protective features include overload protection set at 200A and short-delay range between 1200 – 2000A. It also has non-delayed short circuit range between 6 – 10A. The switching capacities are 150 kA at 480Y/277 V 60 Hz, 50 kA at 600Y/347 V 60 Hz, and 100 kA at 480 V 60 Hz. It adheres to UL/CSA and IEC standards and is designed to be installed as a fixed, box terminal type unit. Its main function is for system and cable protection.
