PEN Fault Detection Devices & PME Protection Units
Shop PEN fault detection devices and PME protection units for EV charging installations, including standalone devices, integrated consumer units, load-balancing and three-phase options.
Open-PEN protection selection depends on the earthing arrangement, supply configuration, charging equipment and the protection already incorporated within the EVSE. Confirm the complete design before choosing a standalone unit or combined board.
Quick guide: A suitable open-PEN protection arrangement can provide automatic disconnection under defined fault conditions. The correct method and device differ between single-phase and three-phase installations.
- Standalone PEN devices: separate protection for a defined EV supply
- PME consumer units: combined board and PEN protection arrangements
- Load-balancing options: selected units for managed EV demand
- Three-phase devices: products designed for compatible three-phase installations

Choosing PEN Fault Protection for EV Charging
Start with the charger specification and supply arrangement. Some EVSE includes open-PEN protection; other installations need an external device or combined consumer unit. Single-phase voltage-monitoring devices and three-phase solutions are not interchangeable.
Standalone Detection Devices
Used where a separate open-PEN protection device is appropriate for the designed circuit. Check switching, supply configuration, enclosure and charger compatibility.
Integrated PME Consumer Units
Combine open-PEN protection with circuit protection and, on selected products, SPD or load-management components inside one enclosure.
Three-Phase & Multi-Charger
Three-phase installations require a protection method designed for that supply configuration. Confirm suitability for the number and phase arrangement of charging points.
Specification Checklist
- Earthing arrangement: establish how the charging point is supplied.
- EVSE protection: confirm what is built into the charger and the relevant product standards.
- Supply configuration: distinguish single-phase from three-phase protection methods.
- Switching: verify which conductors the selected arrangement disconnects.
- Additional devices: coordinate RCD, RCBO, SPD and load management with the complete design.

Design responsibility: open-PEN protection must be selected as part of the complete EV charging installation. Check the current charger, device and installation documentation before ordering.
