Application
n
The vigi earth leakage module option disconnects the circuit breaker when an
electrical earth fault is detected
n
Used to overcome high earth fault loop impedance and associated excessive
disconnection times eg long cable runs
n
Enhanced personal and equipment protection
Technical data
Adjustable sensitivity and
time delay settings
For discrimination with other RCDs
Protection against nuisance
tripping due to transient
overvoltages etc.
