AD-12 EKF Basic series residual current circuit breakers (RCBOs) are devices that combine the functions of a miniature circuit breaker with a residual current device. Upon detection of a leakage current (fault) to ground or an overcurrent (overload or short circuit) in the protected network section by the circuit breaker, the device trips, resulting in the disconnection of the protected network.
