EARTH LEAKAGE RELAYS

Earth leakage current give rise to temperature and progressive failure of insulation which leads to operating flash overs. It is essential to detect earth leakage current well before they cross threshold limits and isolate the circuit.

FEATURES:

Solid state.
Wide operating current range.
Low power consumption.
Variable current and time settings.
Fault indication.
Test and reset facility.
Ideal for compliance to IE rule 61-A
