Remote indications

Vigi add-on may be equipped with an auxiliary contact (SDV) to remotely signal tripping due to an earth fault.

Use of 4-pole Vigi add-on with a 3-pole CNSX

In a 3-phase installation with an uninterrupted neutral, an accessory makes it possible to use a 4-pole Vigi add-on with connection of the neutral cable.

Power supply

Vigi add-on are self-powered internally by the distribution-system voltage and therefore do not require any external source. They continue to function even when supplied by only two phases.

A Sensitivity setting
B Time-delay setting (for selective earth-leakage protection).
C Lead-seal fixture for controlled access to settings.
D Test button simulating an earth-fault for regular checks on the tripping function
E Reset button (reset required after earth-fault tripping).
F Rating plate
G Housing for SDV auxiliary contact.

Vigi 3P add-on may also be used on 3P circuit breakers used for two-phase protection.
If the sensitivity is set to 30 mA, there is no time delay, whatever the time-delay setting.

Operating safety

The Vigi add-on is a user safety device. It must be tested at regular intervals (every 6 months) via test button.
