NZM6B-63/ZM6A-40-NA Eaton Molded Case Circuit Breaker

The NZM6B-63/ZM6A-40-NA is a molded case circuit breaker with a fixed thermal trip setting of 40A and an adjustable magnetic trip range of 260–500A. Its rated short-circuit interrupting capacity is 25kA at both 240V and 480V, and 14kA at 600V. This device is designed for overcurrent protection in industrial electrical distribution systems where precise thermal-magnetic coordination and defined interrupting performance are required across common low-voltage system voltages.
