Earth continuity relay schneider.

The ecm3 relay monitors a low voltage dc signal applied between the pilot and earth of the cable and by measuring this signal determines the resistance of the pilot earth loop. The output contacts change its position if the relay detects a failure in the continuity of the circuit. The ic3 utilises microprocessor technology to provide a greater level of stability over longer pilot cables by using digital filtering techniques.
