More info
▲Undervoltage release, 220-250VDC
Optional accessories for the circuit-breaker series NZM offers a comprehensive portfolio of application options for use world wide. The mounting is always flexible and easy thanks to the modular function groups. Notes: non-delayed disconnection of NZM circuit-breaker or N switch-disconnector when the control voltage sinks below 35-70% US. For use with Emergency-Stop devices in conjunction with emergency-stop button. when the undervoltage release is de-energized, accidental contact with the main contacts of the switch during attempts to switch on is safely prevented . Undervoltage releases cannot be installed simultaneously with NZM..-XHIV.. early-make auxiliary contact or NZM..-XA.. shunt release. Can be used for: NZM4(-4), N(N/O)4(-4)
