3 AC RCD Type B

The 3 AC RCD Type B module contains a residual current device (RCD). This device has been designed for three-phase installations that detect fault currents flowing to earth that are too small to trip a circuit breaker, but sufficient to cause an electric shock or an electrical fire. The RCD is also equipped with auxiliary contact for monitoring purposes.
