The WARTD280-100 A-Type 100mA Time Delay RCD is a 2 Pole S-Type device rated at 80A. Designed for upstream use in selective coordination systems, its built-in time delay ensures only the RCD closest to the fault disconnects, avoiding unnecessary shutdowns of healthy circuits. Ideal for EV charging points, renewable energy installs, and industrial distribution boards, it’s fully compliant with BS EN 61008-1 and the 18th Edition Wiring Regulations.

Installer Tip: Use 80A time delay RCDs upstream in dual-RCD or multi-board systems. Always confirm load rating and coordination requirements before selection.
