What it is

The Lewden SRG1VCU-RM is a surge protection kit in an IP20 steel enclosure, combining a main switch, an MCB and the SRG1VCU surge protection device (SPD), for retrofit installation alongside an existing consumer unit.

Signs this part needs replacing

  • The SRG1VCU surge protection module shows a fault indicator, where fitted
  • The main switch or MCB will not reset after tripping
  • Physical damage to the enclosure, main switch or MCB
  • A known surge event (lightning strike or grid fault) after which the installation has not been checked

Before you order

  • Confirm your consumer unit does not already have integral surge protection before adding this unit
  • This is an electrical installation component; fitting must be carried out or checked by a qualified/registered electrician
  • Isolate the supply before any work on the enclosure
