Earth-leakage protection relay X35DB3

currentACDC

The X...DB3 series earth leakage relays Type B are designed to measure the DC, AC and high frequency leakage current. 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: total RMS, AC fundamental, AC high frequency - Double threshold: total RMS and DC component - Storing of the intervention current values - Internal clock and storage of the last 10 events - RS485 Modbus RTU, measurements, event archive, scope - Selectable antifibrillation filter with re protection 300mA - AC measurements up to 10kHz - Automatic retry - Logic Selectivity - Selectable 3rd harmonic filter
