Description
The Vigi earth leakage module is electromagnetic. It operates without an auxiliary
power supply. The C60 Vigi module combines the relay and toroid in a single unit.
These may not be fitted to 1 pole or 3 pole MCBs.
Instantaneous
It ensures instantaneous tripping (without time-delay).
Selective
s
Complete vertical discrimination is ensured if the following two conditions occur
simultaneously:
The downstream device is an instantaneous device and the upstream device is a

s
or time-delay device
The sensitivity IDn of the downstream device is less than IDn/2 of the upstream

device
Combination
The C60 circuit breaker + C60 Vigi module combination constitutes a residual current
device in compliance with BS EN 60947-2 and BS EN 61009.
