The WPKPME08/C40 is an IP65 PME consumer unit combining a 40A MCB with PME fault monitoring for a single-phase EV charging circuit. It is the simplest configuration in this four-model family, with no integral RCBO and no factory-fitted SPD.
This model is intended for designs where the necessary residual-current protection and any required surge protection are already provided elsewhere. The MCB supplies overload and short-circuit protection only.
Installer Tip: Confirm where the required residual-current and surge protection are provided before selecting this model. For a factory-fitted SPD, compare the WPKPME08/SP.
Key Features
- 40A MCB – overcurrent and short-circuit 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
- No integral RCD or RCBO – residual-current protection must be provided by the circuit design
- No factory-fitted SPD – surge protection must be assessed separately
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.
