The MEC2100 is a compact 2-module metal meter isolator with a 100A Double Pole Main Switch and twin screw terminals for secure tail clamping. Installed between the electricity meter and consumer unit, it provides clear, safe isolation - now increasingly required by DNOs and supply authorities as part of standard installation practice.

Where it’s used: new domestic installs, rewires, and distribution upgrades. The MEC2100 makes future maintenance or meter swaps straightforward by providing a dedicated point of disconnection. Its robust metal enclosure, colour-coded handle, and sealable screw lid give installers and inspectors confidence on compliance and ease of use.

For outdoor meter boxes, pair with an IP65-rated enclosure and a tails gland for compliant cable entry. Often installed alongside 100A terminal blocks and metal consumer unit enclosures as part of a full upgrade.

  • 100A rated main switch – 2 pole with twin screw terminals
  • Compact design – 2 module metal enclosure
  • Secure tail termination – supports 16mm² and 25mm² meter tails
  • Colour-coded handle – fast visual identification
  • Dimensions: 74mm (W) × 175mm (H) × 90mm (D)

Now a standard part of the contractor’s toolkit, especially in meter-box-ready installs. Fully compliant to BS EN 61439-3 and ready for residential and light commercial sites.
