NZM2/3-XU24DC Catalog No. 259509** **EL-Nummer 0004358769 (Norway)** Similar to illustration ## **Delivery program** Product range Accessories Accessories Undervoltage release Accessories Undervoltage releases Standard/Approval UL/CSA, IEC Construction size NZM2/3 Description 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 connection with an emergency-stop button. When the under-voltage trip is switched off, accidental contact with the circuit breaker’s primary contacts is prevented when switched on. Undervoltage releases cannot be installed simultaneously with NZM...-XHIV... early-make auxiliary contact or NZM...-XA... shunt release. Connection type With bolt connection Auxiliary contacts without auxiliary contact Rated control voltage Us V 24 V DC For use with NZM2(-4), N(S)2(-4) NZM3(-4), N(S)3(-4) ## **Technical data** ## **Undervoltage release** |**Technical data**
