Description
The ELR electronic residual current relay allows monitoring and protection of the
low voltage distribution network, through the use of a toroidal transformer.
Protection is achieved in combination with the MCBs and MCCBs. The ELR front panel residual current relay is compliant with protection standard 60947-2 Annex M in order to offer a cumulative operational time (residual current relay, shunt-trip, circuit breaker) guaranteed by the manufacturer.
