Remote Reset and Autoreset functions. The output contacts of the ELR residual current relays can be reset remotely, using push-buttons. Also, when the fault will be removed from the network, the relay contacts will switch automatically, without the need to press the reset button from a local or remote position.

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 stand. ... 5.

The new range of ELR front panel residual current relays has been tested in combination with miniature circuit breaker (S200 range) and moulded case circuit breakers (Tmax series up to T5 630 A) conforming with IEC/EN 60947-2 Annex M. In order to ensure compliance to IEC/EN 60947-2 Annex M ABB has considered the following parameters:

I relè differenziali della nuova gamma ELR permettono, tramite un selettore, di abilitare o escludere la sicurezza positiva (fail safe). Impostato su sicurezza standard (Fail Safe OFF) il relè aziona la bobina di sgancio nel caso in cui venga rilevata una corrente di guasto e anche nel caso in cui venga a mancare
