The WMTP36-R40CSP is a complete 3 phase PME consumer unit for three EV chargers. It is supplied in a 36-module IP40 steel enclosure with 3 x 40A four-pole RCBO outputs, two PME fault detectors, a 100A main switch and Type 2 surge protection.
This model is designed specifically for installations serving three three-phase EV charge points. It combines the distribution, individual circuit protection, surge protection and open-PEN protective arrangement within one pre-wired assembly.
Installer Tip: The WMTP36-R40CSP is the three-output three-phase charger model. Choose the WMTP28-R40CSP for two three-phase chargers or the WMTP28-WER40CSP where six single-phase charging outputs are required.
Why Choose a 3 Phase PME Consumer Unit?
EV charge points connected to a PME supply require an appropriate protective measure against the consequences of an open-PEN conductor. The WMTP36-R40CSP combines PME fault detection with the protective and switching equipment required for three independently protected three-phase charger circuits.
When a qualifying abnormal supply-voltage condition is detected, the protection arrangement operates to isolate the EV charging installation. Its suitability—including whether a separate earth electrode is unnecessary—must be confirmed by the installer from the complete installation design and the applicable edition of BS 7671.
- Dedicated three-charger configuration – designed for three three-phase EV charge points
- 3 x 40A four-pole RCBO outputs – individual protection for each charger circuit
- Two PME fault detectors – monitors the three-phase supply for open-PEN fault conditions
- Type 2 surge protection – helps protect connected equipment from transient overvoltages
- 100A main switch – provides a single incoming switching point
- Pre-wired and tested in the UK – reduces on-site assembly work
Protection for Three Three-Phase EV Chargers
This page relates specifically to the WMTP36-R40CSP. Its three 40A four-pole RCBO outputs are intended to supply three three-phase chargers from a 400/415V three-phase installation.
The connected chargers must include the DC leakage protection required by the charger manufacturer and the applicable installation requirements. Device compatibility, maximum demand, diversity, load management and upstream protection must all be verified during circuit design.
