NZM4-XU2A24DC

NZM4-XU2A24DC. Undervoltage release for NZM4, configurable relays, 2NO, 24DC, Push-in terminals

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: Undervoltage releases with two relays. Non-delayed disconnection of circuit-breaker NZM when control voltage drops below 35 - 70 % Us. For use with emergency switching off devices in conjunction with emergency switching off buttom. For signalizing commands or different states of the circuit-breaker. Two relays per unit. Actuation reason can be configured in the trip unit . Configuration via communication or circuit breaker display or front USB connection and Eaton Power Xpert Protection Manager. When the undervoltage release is de-energized, accidental contact with the main contacts of the circuit-breaker dureing attempts to switch on is reliably prevented. Only suitable for use in conjunction with circuit-breakers with electronic releases. Undervoltage release relais modules cannot be installed simultaneously with early-make contact NZM…-XHIV, or untervoltage release NZM…-XU…, or shunt release NZM…-XA… Relay coil actuated by trip unit. Relay contact for control wiring. Control wiring to push-in terminals . Cannot be used with PXR10 NZM-AE electronic release.
