The ELRC-B, with all features and wide tripping current and time setting ranges of the ELR’s family, has been manufactured in a compact design of 6 modules DIN (17.5 mm) with a built-in Toroidal Transformer of 28 mm inner diameter for the passage of the cables.
All this allows to reduce to the very minimum the wiring, the overall dimensions and to avoid the disturbances, due to the possible electromagnetic fields which could be coupled to the wiring between the T/T and the ELR.
It also has a micro switch, which allows the selection of the working method of the end relay. This could be as normally de-energized (not tripped) or normally energized (fail safe).
So as for the rest of the ELR’s range, the preset ELR is fitted with the appropriated filters at the input circuits to make it immune to external disturbances and the electronically control of the internal circuits and the T/T.
