WebEarth 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. WebIn case of a fault the resistance of the mains to earth decreases. The resulting earth-leakage current flow is sen-sed by the unit. When the earth-leakage current exceeds the set response value, the output relay energizes with delay (see characteristic) and the red "fault" LED lights. Examples of use The earth-leakage monitor CM-IWN-AC is ...
