This is a plug-in kit for 3 poles Vigicompact NSX 400/630 fixed circuit breakers (circuit breaker with Vigi add-on module).A plug-in configuration is made by adding a plug-in kit to a fixed Vigicompact NSX device.This kit includes a plug-in base (LV432516), 3 power connections (LV432519), 2 short terminal shields (LV432591) and a safety trip interlock (LV432520).A plug-in configuration allows to install or extract rapidly and easily the circuit breaker from its base.This operation can be done without connecting or disconnecting the power circuit.
