TYPE A-F Compact Digital Earth Leakage Relays X --- DL3 Range

The X...DL3 series earth leakage relays are designed to measure the leakage or unbalanced currents caused by conductors or appliances insulation losses and to react, in case the set limits are exceeded, switching off the power supply to the defective system. Thanks to their distinctive feature (the displaying of the leakage current) it is possible to continuously monitor the insulation state and to program the preventive maintenance in order to avoid unexpected power breaks.
