Description
Three-Phase EV Consumer Unit with O-PEN® Technology & 3 x 32A Type A Curve C RCBOs
matt:e EVU-3-32-R
Safe, Compliant, and Cost-Effective EV Charging Connection Solution
The Ultimate Three-Phase EV Charging Protection
The matt:e EVU-3-32-R EV consumer unit is a three-phase connection centre designed for safe and regulation-compliant EV charger installations. Featuring integrated O-PEN® technology, it allows EV charge points to connect to PME (TN-C-S) earthing systems without the need for earth electrodes. This significantly reduces installation costs and complexity, making it an ideal solution for commercial and residential three-phase EV charging setups.
Equipped with 3 x 32A Double Pole Type A Curve C RCBOs, the unit provides robust circuit protection against overloads, short circuits, and residual currents. Its phase loss protection further enhances safety by detecting supply failures and preventing unsafe operation.
Designed to comply with BS 7671:2018 A1 (2020) Regulation 722.411.4.1 (iii), this unit simplifies EV charger installations while ensuring maximum reliability.

Understanding PEN Loss and PME Faults
- PEN Loss (Protective Earth & Neutral Loss): A dangerous fault in PME (Protective Multiple Earthing) systems where the neutral conductor is lost, potentially exposing users to hazardous voltages.
- PME Fault: When the earth-neutral link in a PME system fails, it can create a serious risk of electric shock.
The matt:e EVU-3-32-R automatically detects PEN faults and ensures safe disconnection, maintaining compliance with BS 7671:2018 A1 regulations.
