Commercial EV
Installations

Three-phase O-PEN® connection centres for commercial EV charging infrastructure. Standardise your installations, eliminate groundworks, and remain fully BS 7671 compliant.

Three-Phase Protection for Commercial Sites

Our commercial connection centres incorporate the patented O-PEN® device for three-phase PME supply installations. When an open PEN condition is detected, the system automatically isolates the supply or individual loads, preventing dangerous touch voltages from exceeding 70V RMS.

Designed for large commercial EV charging infrastructure, these units standardise your installation process across charge points while eliminating the need for service location scanning and minimising civil works requirements.
