Earth Leakage Relays

We manufacture and export a wide range of Earth Leakage Relays which comprises N22, N45, N96, N96 –D, Series-1 and DC Earth Leakage Relays. These relays give rise to temperature and progressive failure of insulation which leads to operating flash over. These are widely used in power substations, generating stations, telephone exchanges and others for control & monitoring systems.
