Undervoltage release, 48 V DC, +2early N/O NZM1-XUHIV48DC Eaton Moeller series NZM - Molded Case Circuit Breaker. Undervoltage release, 48 V DC, +2early N/O, 1 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: for interlocking and load-shedding circuits, as well as for early-make of the undervoltage release in main-switch applications. For use with Emergency-Stop devices in conjunction with emergency-stop button. when the shunt release is energized, accidental contact with the main contacts of the switch during attempts to switch on is safely prevented . Early make of auxiliary contacts on switching on and off (manual operation): approx. 20ms. Undervoltage releases cannot be installed simultaneously with NZM..-XHIV.. early-make auxiliary contact or NZM..-XA.. shunt release. Can be used for: NZM1(-4), N1(-4)
