The WECRC100 is the highest-rated model in our RCD upgrade unit range, pre-fitted with a 100A 30mA RCD inside a 2-module plastic enclosure. It provides reliable residual current and earth fault protection where consumer units or distribution boards lack integrated RCD cover.

Engineered for heavy-duty domestic incomers, larger sub-mains, and commercial applications, the WECRC100 delivers robust protection while maintaining a compact, surface-mounted footprint. Tamper-proof seal screws ensure compliance and security on site.

Installer Tip: Select the 100A unit when protecting main incomers or high-capacity subcircuits. For smaller domestic circuits, step down to the 40A or 63A models.
