Eaton Moeller series NZM - Molded Case Circuit Breaker. Undervoltage release for NZM2/3, configurable relays, 2NO, 1 early-make auxiliary contact, 1NO, 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 one early-make contact and two relays. For interlocking and load-shedding circuits, as well as for early-make of the undervoltage release in main-switch applications. 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. Early-make of auxiliary contacts on switching on and off (manual operation): approx. 20 ms (NZM2/3) and 90 ms (NZM4). Only suitable for use in conjunction with circuit-breakers with electronic releases . Connot be used in conjunction with remote operator NZM…-XR… 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.
