Provides electrical isolation between the DNO kWh meter and consumer unit or distribution board.
The isolation switch permits the supply to the installation to be interrupted without withdrawing the DNO cut out fuse.

• Available as either an empty enclosure or with integrated main switch.
• Manufactured from durable ABS material, the insulated enclosure features two separate interlocking covers, permitting the installation and separate security sealing of supply and load conductors.
• Supplied complete with cable entry plugs to maintain ingress protection when DNO service head and meter are installed prior to consumer unit installation.
