Shunt release for NZM2/3, configurable relays, 2NO, 24AC/DC, 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: Shunt releases with two relays. Switches are tripped by a voltage pulse or by the application of uninterrupted voltage. 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 shunt release is live, contact with the circuit-breaker's main contacts on switching on is reliably prevented. Only suitable for use in conjunction with circuit-breakers with electronic releases. Shunt 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.

Product Overview

A shunt release accessory is an electromechanical device mounted inside circuit breakers to remotely trip the switchgear upon receiving an external voltage signal, providing essential emergency stop capabilities in industrial power architecture. This Eaton Moeller NZM2/3-XA2A24AC/DC unit interfaces directly with control loops to interrupt power safely.

Pricing, availability and lead time are confirmed per enquiry through an RFQ.

Product specifications

Type
Special features
  • The breakers are actuated by a voltage pulse or by applying a no-break current.
  • For signalizing commands or different states of the circuit-breaker.
  • Two relays per unit.
  • The activation criteria can be configured in the trip unit.
  • Configuration via communication or circuit breaker display or front USB port and Eaton Power Xpert Protection Manager.
  • If the shunt trip is live, contact with the circuit breaker’s primary contacts is prevented when switched on.
  • Only for use in combination with circuit-breakers with electronic trips.
  • Shunt trip relay modules cannot be installed simultaneously with make-before-break auxiliary contact NZM...-XHIV, under-voltage trip NZM...-XU... or shunt trip NZM...-XA.
  • Relay coil is controlled by trip unit.
  • Relay contacts for control wiring.
  • Relays can be used for controlling remote operator with Us=208-204 V AC.
  • Control wiring on push-in clamps.
  • Cannot be used with the PXR10 NZM-AX electronic trip.
