The K RCD300M2 Residual Current Relay is a protective device that monitors residual current to detect imbalance in electrical circuits. It accepts a supply within 19–29 VAC or 22–32 VDC and provides a 125 VAC, 5 A output. The combination of dual-supply compatibility and a 125 VAC 5 A output defines its role in safeguarding systems by signaling on fault conditions with a reliable output.
