Residual Current Monitor (RCM) detects current leaking outside its normal circuit path. In power circuits, current flows only in the phase and neutral wires. Current flowing in the ground wire (or other path to ground) and through the exposed metal parts within the rack, presenting a significant danger for humans is known as leakage current.

Brief Introduction: The AC DC leakage current sensor is installed on the positive and negative output lines of the AC or DC circuit. When the device is in operation, it can detect the output signals of each branch sensor in real time. When the branch insulation is normal, the current flowing through the sensor is equal in magnitude
