Frer Earth Leakage Relay

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 o 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. Main functions: - Continuous digital indication of the leakage current - Logic Selectivity - Automati retry - Internal clock and storage of the last 10 events - RS485 Modbus RTU, measurements, event archive, scope - Selectable anti€brillation €lter - Storing of the intervention current values - Measure and display of the THD - Selectable 3rd harmonic €lter - AC measurements up to 10kHz
