NZM1-XUHIV18DC Eaton Molded Case Circuit Breaker

The NZM1-XUHIV18DC is a molded case circuit breaker identified with an undervoltage release. This release function monitors the circuit’s supply voltage and responds when that voltage falls below the level required for normal operation, allowing the breaker to open through its release mechanism. Its inclusion makes the model suitable for molded case circuit breaker applications where undervoltage condition detection is required. The molded case format combines the circuit interruption role of a breaker with a release designed for response to insufficient supply voltage. The NZM1-XUHIV18DC designation identifies the breaker and its fitted release configuration, while undervoltage release defines the specified feature and its intended circuit voltage monitoring application.
