From the Schneider Brand, this RCCB-3 pole is designed to interrupt the flow of electricity if there is a current leakage to the ground, which usually occurs when someone comes into direct contact with a live electrical part. RCCB is very effective in preventing electric shock and fire caused by leakage current. RCCB is often used in installations in wet areas such as bathrooms and kitchens, where the risk of current leakage is higher.

With sensitivity tripping settings at 30mA used in residential and 300mA often used in industrial or commercial environments.
