The matt:e O-PEN Interlock Panel is a dedicated PEN Fault Detection unit with built-in O-PEN® technology that allows for connection of large three-phase loads to the existing PME earthing facility.

The unit is designed to control two field supplied contactors to isolate the load - disconnecting all live conductors and earth in the event of a fault, facilitating compliance with BS: 7671, 2018 Amendment 1 2020 Regulation 722.411.4.1(iii).

The field supplied contactors can be selected to protect any size load and are ideal for protecting a 250A distribution board supplying multiple EV charge points.

The O-PEN technology does not require earth rods or electrodes to function correctly.


  • Built-in O-PEN® technology
  • No Earth Rods or Electrodes required
  • Protects any size load through field supplied contactors
  • Auto Reset, once fault has cleared
  • Simple wire-in, wire-out connection
  • Designed and built in the UK
