The MCCB-RLP is designed to monitor and control electrical circuits, detecting potential faults such as overloads, short circuits, and earth faults. However, its standout feature lies in its residual leakage protection function, which detects and responds to any unwanted leakage of current to earth. This leakage current, often caused by damaged insulation or faulty equipment, can pose a significant risk of electric shock or fire hazards.
