NZM1-XUHIVL380-440AC Eaton Molded Case Circuit Breaker

The NZM1-XUHIVL380-440AC is a molded case circuit breaker fitted with an undervoltage release. The release is the specified control feature for this model, allowing the circuit breaker to respond when supply voltage falls below the required operating level. The 380-440AC portion of the model designation identifies the associated AC voltage rating used to determine whether the device is suitable for a given installation or application. This component is intended for industrial circuit breaker fitment where undervoltage release operation is required, rather than for use as a general-purpose circuit breaker without that release function.
