This new series of Earth leakage relays , on top of granting a high reliability level , like the previous models , have evolved the technical and mechanical characteristics . One of its main novelties is the reduced depth . It may be coupled to any of Toroidal Transformers . The instrument , fitted with filters at the input circuits, is practically im-mune to external disturbances . double output changeover contact, one can be used for disconnection and the other for an alarm function . selectable negative or positive safety (fail safe) by means of a dipswitch .The fail safe offers to avoid leaving the installation operative without protection . Mechanical signalling of tripped relay (only per ELR-2M) .
