A Surge protection kit specifically developed for Hager consumer units. Developed to ensure optimal performance of SPD technology within residential single phase consumer units. SPD is CT2 type to ensure compatibility with all common UK Earthing arrangements e.g. TN-C-S (PME), TN-S and TT earthing arrangements. This is an IEC Type 2 / class II SPD for single phase power supply networks.

This SPD kit fits within the standard consumer unit with exception of a split load dual RCD board where the SPD needs to be fitted on the high integrity side of the board. Line connection is provided by the busbar, Neutral and Earth connections are via 6mm cable links from the top of the SPD to the earth and neutral terminal bar.
