  • Measured/monitored value:


  • Contact configuration:

    1 NO/NC, 2 NO/NC

  • Other characteristics:

    panel-mount, flush-mount

  • Trigger voltage:

    Max.: 415 V

    Min.: 12 V


The ELR 1E is a elementary unit of the latest series which is used mainly to decrease flush mounting ELR option, other than any other option. The most creative feature of the product is its decreased depth ( 60 mm which includes terminals).

The unit could be combined with any of the Toroidal transformers of the CT - 1 and CTA - 1 close core and split core families respectively. There are multiple versions available for adhering to various auxiliary supply needs. The unit's broader time range and ongoing setting ranges enable preference over tripping features, for preserving the contact values beneath 50 V as per the norms of IEC.

The product offers the best return on investment while other ELR's or /and RCD's downstream or upstream in the line are to be safeguarded. The instrument when attached with filters at the input circuits is highly resistant to outside interference.
