The WEV263B-030 is a 2 Pole Type B RCD (63A, 30mA) designed for higher-load single-phase installations where smooth DC residual currents or high-frequency leakage may be present. Unlike Type A RCDs, it safely detects AC, pulsed DC, and smooth DC faults up to 1000 Hz, ensuring full protection where standard devices are not sufficient.
Rated at 63A, this RCD is the installer’s choice for larger EV charging points, heat pump consumer units, solar PV arrays, UPS setups, and industrial inverter systems. Fully compliant with IEC/EN 62423 and BS7671:2018+A2, it delivers reliable fault disconnection for demanding projects.
Installer Tip: Choose the 63A rating when circuit demand is higher than 40A or when multiple heavy-load devices (EV chargers, UPS, PV inverters) are connected on the same system.

When should I use the 63A Type B RCD?
When the circuit demand exceeds 40A or when multiple high-load devices such as EV chargers, solar inverters, or UPS units are connected.
Is this suitable for industrial use?
Yes – the 63A rating makes it suitable for heavy-duty single-phase applications in industrial and commercial setups.
What’s the difference between the 40A and 63A models?
The 40A WEV240B-030 is suited for smaller domestic or light commercial circuits, while the 63A WEV263B-030 is built for higher demand installs.
Is it compliant with UK wiring regulations?
Yes – certified to IEC/EN 62423 and fully compliant with 18th Edition Amendment 2.
Does it include test functions?
Yes – all Type B RCDs feature built-in test buttons and should be regularly tested as part of inspection and maintenance.
