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.
Key Benefits
No Service Location Scanning
Eliminates the need for buried service scanning before installation, saving time and cost on every job.
Minimal Civil Works
No need for earth electrodes or complex groundworks. Direct connection to PME supply with consistent earth resistance year-round.
Metal Structure Compatible
Units can be mounted directly on metal-clad structures without additional earthing requirements.
Standardised Process
Provides a consistent, repeatable installation procedure across all charge points, reducing error and training requirements.
Automatic Fault Isolation
Open PEN conditions are detected and isolated automatically, protecting users from dangerous touch voltages.
Made in Great Britain
Designed and manufactured in the UK to exacting quality standards.
