Technical Data Parameter Specification Product Type Undervoltage Release (UVR) - Accessory Compatible Series NZM1 Molded Case Circuit Breakers Rated Control Supply Voltage (Us) 24 - 240 V AC/DC (Wide range, auto-sensing) Note: This is a common specification for the 'XKSA' model. Always verify the nameplate. Tripping Delay Typically 1 - 3 seconds (to avoid nuisance tripping on brief dips). Function Automatically trips the breaker when voltage drops below the threshold. Prevents the breaker from being closed if the control voltage is insufficient. Mounting Factory-installed or field-mounted on the side of compatible NZM1 breakers. Connection Screw terminals for control wiring. Standards IEC 60947-1, IEC 60947-2
