ELR-3AN Tripping set-point 0,03...30A. 2 thresholds. Log. RS485.

Earth differential relay with associated toroidal sensor input, measures the leakage current in an electrical installation to detect levels that could be harmful. Ideal for protection or alarm, the product offers multiple settings. 2 relay outputs (ALARM and TRIP) each with 1 changeover contact. RS-485 communication with Modbus RTU protocol available. Log tripped residual current
