Under Voltage Release for Motor Protection Circuit Breakers
Hager MZ529N Under Voltage Release
The Hager MZ529N Under Voltage Release is a safety accessory designed for use with compatible Hager motor protection circuit breakers. It automatically trips the breaker when the control voltage drops below the required level, helping prevent unsafe or unexpected motor restart.
Operating on a 400V AC control voltage, the MZ529N ensures that motors and electrical equipment disconnect safely during power loss or voltage drop conditions.
