What Makes This Unit Ideal for EV Charging?
The EV40AXBD includes a bi-directional RCBO—essential for future-ready EV charging that may involve power export (e.g., solar PV or V2G setups). Its pre-fitted SPD ensures compliance with surge protection rules under BS 7671, helping to safeguard EVSE equipment.
This kit does not include a tail clamp and does not support tail clamp retrofitting.
The Benefits of Bi-Directional RCBOs
Bi-directional RCBOs offer residual current protection in both current flow directions. This is critical in EV and renewable energy setups where energy may be fed back to the grid or redistributed internally. The FuseBox 40A bi-directional RCBO is ideal for such circuits, with 30mA sensitivity and Curve B fault protection.
