DC Earth Leakage Relay.

Our standard DC Earth leakage Relay is a self powered device, measures each pole from the connected dc supply and provides a local led alarm and remote indication via volt free relay contacts if either one is partially or totally shorted to earth.

The DC Earth leakage Relay is covered by a 2 year warranty against defects in workmanship or component failure. Please see our guarantee page for more details

DC Earth leakage Relay responding to a negative or positive earth fault will illuminate the appropriate led on the unit facia indicating precisely which pole is earthed. The internal relay trips to provide a warning signal. The DC Earth leakage Relay is capable of detecting earth faults on charger rectifiers and transformer secondary as well as standard dc supplies from batteries or power supplies.

The DC Earth leakage Relay includes on-board through label healthy and failure leds, one per pole and includes a double pole volt free relay rated at 3A @ 230VAC or 30VDC. Connections and installation requires an 11 pin octal base which is supplied with the relay.

The DC Earth leakage Relay is not suitable for use in vehicles using a positive or negative earthed chassis for obvious reasons (special automotive versions are available for vehicle applications including electric vehicles) but if you use batteries in marine applications, using the steelwork as a conductor is not desirable and this unit then comes into its own. It makes sure your installation floats with respect to earth.

Available in the same voltage range as our other monitors, the Earth Leakage Alarm Relay is suitable for use on 6, 12, 24, 30, 48, 110 and 220VDC systems. Special models configured for the mining and automotive industries can be manufactured to order including versions with isolated power inputs and non-intrusive current sensing via a CT.
