An RCBO combines residual current protection (against earth leakage and electric shock) and overcurrent protection (against overload and short circuits) in a single high-performance device rated for currents up to 63 amperes.
It constantly monitors electrical balance. If leakage current exceeds safe thresholds or if electrical demand surges dangerously, the unit automatically trips to disconnect power, preventing severe shock hazards and electrical fires.
It is widely used in residential distribution boards, commercial facilities, and industrial environments requiring reliable current protection for high-power electrical circuits.
While an RCCB detects residual leakage currents only, an RCBO integrates residual current protection with short-circuit and overload protection, eliminating the need for a separate MCB.
It is recommended to test the device periodically (typically monthly or semi-annually) by pressing the built-in "T" test button to ensure the internal tripping mechanism operates smoothly.
