WEV4100B-030 is a 100A 30mA 4 Pole Type B RCD designed for applications where smooth DC residual currents and higher-frequency AC residual currents may be present. Suitable for EV charging installations, solar PV systems, UPS systems and frequency converters, it provides broader protection than conventional RCD types.

Rated at 100A, this Type B RCD is designed for higher-capacity three-phase electrical systems including commercial EV charging, solar PV installations, UPS equipment and industrial inverter applications. It complies with IEC/EN 61008-1 and IEC/EN 62423, providing reliable protection against AC, pulsating DC and smooth DC residual currents.
