CNSX Vigi add-on

Addition of the Vigi add-on does not modify circuit-breaker characteristics:

compliance with standards
degree of protection, class II front-face insulation
positive contact indication
electrical characteristics
trip-unit characteristics
installation and connection modes
indication, measurement and control auxiliaries
installation and connection accessories.

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.

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.
