The WAR463-030 is a 4 pole, 63A Type A RCD with high immunity, engineered to reduce nuisance tripping on circuits affected by surge currents or harmonics. Fully compliant with BS EN 61008-1 and BS EN 61008-2-1, it provides reliable residual current protection for three-phase distribution boards, EV charger installs, and other sensitive loads.
By using a high immunity design, this RCD maintains safety while filtering out brief disturbances that can cause standard Type A devices to trip unnecessarily. The 4-pole configuration ensures full protection across three-phase + neutral applications.
Installer Tip: Choose a high immunity Type A RCD where circuits include equipment with switching power supplies, drives, or frequent surge activity — such as EV chargers, HVAC systems, and LED lighting banks.
