Vigi earth-leakage protection modules
Compliance with standards
IEC 60947-2, annex B.
b
Decree dated 14 November 1988 (for France).
b
IEC 60755, class A, immunity to DC components up to 6 mA
b
operation down to -25 °C as per VDE 664.
b
Remote indications
Vigi modules may be equipped with an auxiliary contact (SDV) to remotely signal
tripping due to an earth fault.
Use of 4-pole Vigi module with a 3-pole Compact NSX
In a 3-phase installation with an uninterrupted neutral, an accessory makes it
possible to use a 4-pole Vigi module with connection of the neutral cable.
Power supply
Vigi modules are self-supplied 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 3Pmodules may also be used on 3P circuit breakers used for two-phase protection.
(2)
If the sensitivity is set to 30 mA, there is no time delay, whatever the time-delay setting.
Operating safety
The Vigi module is a user safety device. It must be tested at regular intervals (every 6
months).
