Whitecliffe WMRC40CSP: Metal Consumer Unit with 40A Type A C Curve RCBO & SPD for Indoor EV Charging

Ensure the safety of your indoor home EV charger with the Whitecliffe WMRC40CSP protection unit. This compact 4-way metal enclosure provides dedicated earth leakage, overload, and surge protection tailored for electric vehicle charging installations. Its robust metal construction makes it suitable for garages, workshops, or other indoor locations.

Integrated C Curve RCBO and Surge Protection

This unit comes pre-fitted with essential protective devices. According to the product information, it includes a 40 Amp Type A C curve RCBO and a Type 2 Surge Protection Device (SPD). The RCBO combines overload protection (40A C curve, suitable for circuits with moderate inrush currents) and residual current protection (30mA Type A - sensitive to AC and pulsating DC leakage, including 6mA smooth DC) in one device. The integrated SPD helps protect your EV charger and electrical system from voltage spikes.

Reliable Indoor Metal Enclosure

Housed within a fully enclosed metal body with a drop-down lid, this unit offers durability for indoor environments (IP40 rated, as indicated for the WME4L enclosure type). The enclosure includes a DIN rail and earth terminal bar, with 25mm & 32mm knockouts for convenient EV cabling entry. The RCBO features a helpful dual-handle system to indicate the type of fault (overload/short circuit vs earth leakage).

Designed for EV Charger Safety

The Type A high immunity RCBO is specifically suited for protecting EV charging circuits, detecting potential DC leakage currents that standard RCDs might miss. Using a dedicated unit like this ensures that only the faulty EV circuit is switched off, avoiding inconvenience elsewhere in the property.
