Residual Current Circuit Breaker
WRD Type A/AC Residual Current Circuit Breaker
Type A residual-current protection covering 25A to 100A. It responds to pulsating DC components as well as sinusoidal AC, which is why the catalogue positions it for individual EV charge points where the vehicle being charged is unknown.

Residual Current Circuit Breaker
WRV Type B Residual Current Circuit Breaker
Type B protection detects smooth DC residual current, which ordinary AC and Type A devices cannot. That matters wherever an installation contains PV inverters, frequency converters or DC-side EV charging — the fault current there is not necessarily alternating.

Residual Current Circuit Breaker
WRT Time-Delay Residual Current Circuit Breaker
Time-delayed Type A device for the upstream position. Delaying the trip lets a downstream RCD clear its own fault first, so one earth fault does not take out the whole installation.
