Earth leakage relay
Earth leakage and fault current relays provide early warning of insulation deterioration and leakage currents. The relay monitors fault current in DC systems and helps prevent damage to machines and personal injury.
Earth leakage and fault current relays provide early warning of insulation deterioration and leakage currents. The relay monitors fault current in DC systems and helps prevent damage to machines and personal injury.
If the current exceeds the set level, the relay responds and indicates a fault.
All our relays can indicate faults in the +/- cable, and some can even detect them in branched systems. This significantly facilitates your maintenance work.
The relays feature LED status indicators, high accuracy, and strong immunity to interference.
