AD-32 EKF PROxima residual current circuit breaker (RCCB) is a device that combines the functions of a circuit breaker with a residual current device. When the circuit breaker detects a leakage current (fault) to ground or an overcurrent (overload or short circuit) in the protected network section, the device trips, leading to the disconnection of the protected network. The AD-32 range is supplemented by AD-32 type A and AD-32 selective RCCBs.
