In the electrical and industrial sectors, RCMU typically refers to a Residual Current Monitoring Unit. It is a critical safety component used to monitor for residual current ("leakage current") in a system in real time. An RCMU is a high-precision sensor or protection device primarily used to detect residual current in both AC and DC.
