Earth Leakage Relays Type B

Earth Leakage Relays are used by OEMs in combination with fault breaking devices such as MCBs and MCCBs, to provide earth leakage detection in special distribution panels under the control of an Authorised Person.

The OEM tests the combination to verify that the total disconnection time is in conformity with EN60947-2 Annex M.
