In addition to the range of SPDs in Type 2 and Combined Type 1, 2 & 3, Lewden has introduced a new Retrofit Surge Protection Unit that meets with the requirements of the 18th edition regulations BS7671:2018 section 534.
This easy to install, self-contained metal enclosure connects in parallel to the existing consumer unit without any need for modification to the unit.
Designed for residential application only on a single phase 230V supply, this unit is suitable for positioning at the origin of an electrical installation, providing protection for all distribution circuits. It includes a main switch and 32A MCB, providing circuit protection, and disconnection of the surge protector for testing or end of life replacement.
