The WAR263-030 is a 2 pole, 63A Type A RCD with high immunity, providing reliable residual current protection for single-phase circuits where nuisance tripping must be minimised. Fully compliant with BS EN 61008-1 and BS EN 61008-2-1, it’s ideal for consumer units, EV charge points, and sensitive loads affected by harmonics or surges.
High immunity RCDs are designed to avoid unnecessary trips caused by transient disturbances while maintaining full safety functionality. This makes the WAR263-030 particularly suited to EV circuits, HVAC equipment, and electronic-heavy installations.
Installer Tip: Use the 2-pole 63A high immunity model for single-phase installs where EV chargers, lighting banks, or inverter-driven systems are present and may otherwise cause nuisance tripping.

What makes this RCD high immunity?
It filters out harmonics and transients that can cause nuisance trips, while still tripping under genuine residual current faults.
Is the 2-pole 63A model suitable for EV chargers?
Yes – it’s often specified for EV installs where DC leakage and harmonics are common.
How is a 2-pole RCD different from a 4-pole?
2-pole devices protect single-phase (line + neutral) circuits, while 4-pole units protect three-phase + neutral setups.
When should I choose a high immunity RCD?
When circuits involve electronic loads, switching power supplies, or EV chargers where nuisance trips are likely with standard RCDs.
