ABB NZMB2-100NA Molded Case Circuit Breaker with Undervoltage Release is an ABB-manufactured protection device identified by the model NZMB2-100NA. This MCCB includes an Undervoltage Release (UVR) feature, described in the data as an Undervoltage Trip, which provides a controlled trip signal when undervoltage conditions are detected. It is rated for 208-240 VAC operation, aligning with standard electrical distribution voltages in that range. The combination of molded-case construction and an undervoltage release defines this ABB component for circuits requiring both MCCB protection and undervoltage tripping functionality.
