DEB71DM24A5 is a modular residual current relay designed to provide protection against insulation or grounding faults when used in conjunction with an MCB and toroidal leakage current sensor. It features adjustable trip levels ranging from 30 mA to 5 A with adjustable alarm delay settings from 0 to 5 seconds, and operates on a 24 to 240 VAC auxiliary power supply. The device includes two SPDT relay outputs with a warning threshold at 60% I?n and an alarm threshold at 80% I?n, along with LED status indication for real-time leakage current monitoring. It offers Type A protection, operates on 1P or 3P systems, and features DIN-rail mounting with dimensions of 35.5 x 81 x 70.5 mm. This relay is suitable for residential, commercial, and industrial installations where protection against electric shock and fire risk is required.
