The WARTD2100-100 A-Type Time Delay RCD is a 2 Pole S-Type unit rated at 100A for heavy-duty upstream protection. Its built-in time delay ensures proper discrimination, allowing downstream RCDs to clear faults first while maintaining supply continuity elsewhere. Perfect for EV charging infrastructure, renewable installs, and industrial distribution boards where system integrity is critical. Fully compliant with BS EN 61008-1 and the 18th Edition Wiring Regulations.

Installer Tip: Choose the 100A 2 Pole model for larger installs where the main incomer needs time-delayed fault protection. Ideal in setups with multiple downstream RCDs or boards.
