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.
