84871122

84871122 is a DIN rail mount MIC relay that controls the overcurrent. The relay closes when the current exceeds the threshold displayed on the front face and opens when it falls below the threshold minus the hysteresis. When terminal Y1 is connected to A1 (+), the output is inverted. The relay opens when the current exceeds the threshold displayed on the front face and closes again when it falls back below the hysteresis (undercurrent).

• Control of AC currents, built-in current transformer
