EL D is a digital relay specially designed in 2021 to protect your facilities from sudden blackout. It gives you an early notification before an Earth Leakage event could occurred.

This advanced design meets IEC 60755 Type A & AC operation to deduce the leakage current level accurately in the network.

Pre-alarm is an early warning activated before the leakage current reaches the threshold for tripping.

• 20 Tripping Events include the types, magnitude of the fault with data and time stamping. It reduces the time needed on fault tracing.
• 40 Operation Events include types of trip, normalise, change of setting, self-diagnosed errors with date and time stamping.

Viewing all settings, live value, tripping event with date & time stamping in one screen. User friendly and easy to use.

Rated IP31 (front) and IP20 (rear)

Protection against foreign objects and water with IP31 (front) and IP20 (rear).

Built-in Modbus-RTU to communicate with SCADA, Building Management System (BMS) and Energy Management Information System (EMiS).

To detect fault and/or wrong connection in Zero Sequence Current Transformer (CTZ).

To display live leakage current in mA or %.

Equipped with an automatic reclosure feature for improved continuity:

• Self resets after a trip

• Restores power after transient faults

• Reduces downtime and manual intervention
