Protect your indoor home electric vehicle charger installation effectively with the Whitecliffe WMRC40BSP protection unit. Housed in a sturdy 4-way metal enclosure, this unit provides specific protection including earth leakage, overload, and surge suppression, tailored for EV charging circuits installed indoors, such as in garages or utility areas.

Integrated B Curve RCBO and Surge Protection

This unit comes conveniently pre-fitted with essential safety components. The manufacturer's information indicates it includes a 40 Amp Type A B curve RCBO and a Type 2 Surge Protection Device (SPD). The RCBO offers combined functionality: 40A B curve overload protection (suitable for circuits with low inrush currents, typical of domestic setups) and Type A residual current protection (30mA AC and 6mA smooth DC sensitivity). The integrated SPD provides crucial protection against transient overvoltages for your sensitive EV charger.

Durable Indoor Metal Enclosure

The fully enclosed metal construction with a drop-down lid ensures durability for indoor applications (IP40 rated per WME4L enclosure details). It includes a DIN rail and earth terminal bar for straightforward installation. Convenient 25mm & 32mm knockouts facilitate EV cabling. The RCBO’s twin-handle system aids in quickly identifying the nature of a fault (overload vs earth leakage).

EV Charger Safety Compliance

Featuring a Type A high immunity RCBO, this unit is designed to handle the specific electrical characteristics of EV chargers, including potential DC leakage. Using such a dedicated protection unit ensures only the EV circuit trips during a fault, maintaining power to other essential circuits.
