The WAR480-030 is a 4 pole, 80A Type A RCD with high immunity, designed for demanding three-phase applications where nuisance tripping must be avoided. Fully compliant with BS EN 61008-1 and BS EN 61008-2-1, it provides dependable residual current protection for distribution boards, EV chargers, and industrial loads.
High immunity RCDs are engineered to filter out transient disturbances and harmonics that can cause standard RCDs to trip unnecessarily, while still providing full AC and pulsed DC fault protection. The 80A rating makes this unit suitable for mid-sized installations where higher load capacity is required.
Installer Tip: Use the 80A 4-pole version for medium-sized commercial and industrial sites — such as workshops, retail units, and multi-charger EV bays — where robust residual current protection is essential.

What makes this RCD “high immunity”?
It resists nuisance tripping from harmonics, surges, or switching disturbances, while still providing protection against residual currents.
Can I use this in an EV charger installation?
Yes – high immunity Type A RCDs are often recommended for EV supplies where harmonics and DC leakage are common.
Is the 80A model suitable for industrial use?
Yes – it’s ideal for medium-sized commercial and industrial installs, including HVAC systems, motors, and distribution boards.
What’s the difference between the 63A and 80A models?
The 80A version provides a higher rated current capacity, making it better suited for circuits with heavier loads or multiple devices.
