The WAR2100-030 is a 2 pole, 100A Type A RCD with high immunity, designed for heavy-duty single-phase applications where maximum current handling and nuisance-trip resistance are essential. Fully compliant with BS EN 61008-1 and BS EN 61008-2-1, it provides reliable residual current protection for consumer units, EV supply points, and commercial single-phase circuits.
High immunity RCDs filter out harmonics, surges, and transient disturbances that cause false trips on standard devices, making them ideal for EV, HVAC, and electronic-heavy installs. The 100A rating provides maximum load capacity in the 2-pole range.
Installer Tip: Select the 100A 2-pole version for large single-phase circuits in commercial premises, multi-EV charger installs, or heavy-load domestic systems requiring maximum residual current protection.
Key Features
- 100A, 2 Pole – protects single-phase (line + neutral) circuits

Where would I use a 100A 2-pole high immunity RCD?
It’s ideal for large single-phase supplies in commercial premises, EV charging hubs, or domestic installs with heavy load demand.
Why choose high immunity over a standard RCD?
High immunity devices reduce nuisance trips caused by harmonics, surges, or electronic loads while still offering full protection.
Is this unit EV-compliant?
Yes – as a Type A RCD with high immunity, it meets BS 7671:2018 A2 requirements for EV circuits.
What’s the difference between the 80A and 100A models?
The 100A unit supports larger load capacity, making it suitable for future-proofing heavy single-phase circuits.
