WEV2100B-100 is a 100A 100mA 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 with a 100mA residual current rating, this Type B RCD is intended for higher-capacity installations where upstream residual current protection is required. It complies with IEC/EN 61008-1 and IEC/EN 62423, providing reliable protection against AC, pulsating DC and smooth DC residual currents up to 1000Hz.

Installer Note: The 100mA version is commonly specified where discrimination between upstream and downstream protective devices is required or where higher residual current settings are appropriate for the installation.
