WEV463B-030 is a 63A 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 63A, this unit is the go-to choice for larger EV charging installations, heat pump boards, solar PV arrays, UPS systems, and variable speed drives. Fully compliant with IEC/EN 62423 and the 18th Edition Wiring Regulations, it provides reliable fault disconnection for demanding projects.
Installer Tip: Choose the 63A version where circuit demand exceeds 40A, or where multiple high-load devices (EV chargers, PV inverters, UPS) are on the same system.
