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 part of the network, 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.
