Shunt release, 380-440VAC/DC NZM1-XAL380-440AC/DC Eaton Moeller series NZM - Molded Case Circuit Breaker. Shunt release, 380-440VAC/DC, L 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: switches are tripped by a voltage pulse or by the application of uninterrupted voltage. If the shunt release is energized, accidental contact with the main contacts of the switch during attempts to switch on is safely prevented.undervoltage releases cannot be installed simultaneously with NZM..-XHIV.. early-make auxiliary contact or NZM..-XU.. shunt release. Can be used for: NZM1(-4), N(N/O)1(-4)

Type
Special features
  • Switches are tripped by a voltage pulse or by the application of uninterrupted voltage.
  • If the shunt trip is live, contact with the circuit breaker’s primary contacts is prevented when switched on.
  • Shunt releases cannot be installed simultaneously with NZM...-XHIV... early-make auxiliary contact or NZM...-XU... undervoltage release.
