Hager proposes a range of blocks differentials. They are very quickly and very easily associable with all our circuit breakers until 63A.
Homologuée NF USES, this range offers advantages and simplicities of implementation, namely:
- speed of the mechanical assembly,
- safety related to associations of functions,
- the conformity of the protectors against the direct contacts,
- ...
The circuit breaker differential is formed of the association of a circuit breaker and a block vigi.
The block vigi is used to ensure the protector of the people against the defects of insulation which cannot be detected by the apparatuses of cut and cutting (circuit breaker, switch...)
Gone up in series with the circuit breaker, the block vigi measurement the residual leakage current while ...
