WCED single-phase PME/PEN fault protection unit in a plastic IP65 enclosure, with 40A RCBO and selectable surge protection, kWh metering and load-management options.
Choose your configuration
- Enclosure: IP65 plastic; check environmental suitability and maintain the enclosure rating at cable entries.
- Surge protection: select the SPD option where required by the installation design.
- kWh meter: measures energy consumption.
- Load management: choose the listed option and confirm its operation and charger compatibility against the exact model instructions.
Metered model upgrade: the plastic metered variants share SKU WPEPME12/LBK. Where the lower-spec version is unavailable, EcoHarmony supplies the higher-spec version including load balancing at no extra cost.
Compare the options and open each configuration in our Knowledge Hub.
Confirm suitability before ordering
Check the exact WCED model documentation and charger requirements with your installer, including earthing arrangements, residual-current and DC leakage protection, any additional equipment and commissioning requirements. This product description does not determine whether an earth electrode is needed for a particular installation.
Dispatch and delivery
Normally same-day dispatch and next-day delivery, subject to availability and checkout delivery options. Contact EcoHarmony for a time-critical installation.
How the load-management option works
On EcoHarmony’s single-phase PME units with load balancing selected, load management cuts power to the charger when the property load reaches the configured limit. When the property load reduces sufficiently, the unit automatically reconnects the supply. The charger then restarts; the charging session should resume automatically, depending on the charger model and its settings. This is supply interruption and reconnection, rather than continuous adjustment of the charging current.
What is included with the selected options?
A CT clamp is included when load balancing is selected. It is not required for the other configurations. A kWh meter is fitted when the metering option is selected. Check the selected variant and any stated higher-specification substitution before ordering.
Supply and operating details confirmed by EcoHarmony, 2 November 2026. Meter certification, communications features and accessory specifications must be checked for the exact supplied model.
Three common ordering mistakes to avoid
From EcoHarmony’s customer enquiries, the common mistakes are choosing the wrong protection for the charger, the wrong size or rating, and the wrong IP rating.
- Protection: identify the exact charger model and what it already includes, then match the installer’s required PEN, residual-current, overcurrent and surge protection.
- Size and rating: confirm the specified current rating, phase arrangement and circuit count, as well as enclosure dimensions and available mounting space. A higher amp rating is not an automatic upgrade.
- IP rating: match the enclosure to its location and exposure. An indoor unit must not be assumed suitable outdoors because it is under cover.
