NZM2/3-XA2A24AC/DC
Eaton Moeller series NZM - Molded Case Circuit Breaker. 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.

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.
