The WPEPME08/SP is an IP65 PME consumer unit for single-phase EV charging circuits. It combines a 40A C Curve Type A RCBO, PME fault monitoring and a factory-fitted Type 2 surge protection device in one pre-wired enclosure.

This version suits installations that require residual-current and overcurrent protection in the consumer unit as well as coordinated surge protection. The RCBO does not replace any DC residual-current protection required by the connected charger, so the complete protective arrangement must be checked before installation.

Installer Tip: Choose this SP model when the design requires both a 40A Type A RCBO and Type 2 surge protection. If SPD protection is provided elsewhere, compare the WPEPME08/C40 RCBO version.

Key Features

  • 40A C Curve Type A RCBO – combined overcurrent and Type A residual-current protection
  • Type 2 SPD – factory-fitted surge protection
  • PME fault monitoring – switches line, neutral and protective conductor through the linked contactor arrangement
  • IP65 enclosure – suitable for appropriately located indoor or outdoor installations
  • Pre-wired assembly – built and tested before dispatch
  • Automatic under-voltage recovery and manual reset following over-voltage operation

PME Fault Protection for EV Charging

The built-in monitoring arrangement checks the supply against the manufacturer’s stated under-voltage and over-voltage thresholds. When a qualifying abnormal condition is detected, the assembly operates its linked switching arrangement to disconnect line, neutral and the protective conductor. Under-voltage recovery is automatic; an over-voltage operation requires manual reset.

Final selection still depends on the charger, supply characteristics, earthing arrangement and the protective devices already present. Installation, inspection and testing must be completed by a suitably qualified person in accordance with the manufacturer’s instructions and the current edition of BS 7671.
