Technical data
Common
The Vigi C120 module incorporates the residual current relay and toroid in a case.
Its earth leakage module is electro-mechanical. It functions without an auxiliary
power supply source and thus has a very wide operating range
Protected against nuisance tripping due to transient overvoltages (lightning strike,
switchgear switching on the network, etc.)
Breaking and making capacity upon short circuit is equal to the breaking capacity
of the circuit breaker
Instantaneous or Selective
