Hager JK101SPD Type 1 + 2 Surge Protection Kit For Invicta3 Type B Distribution Boards

Hager JK101SPD Description

A Surge protection device (SPD) kit specifically developed for Hager standard TPN (Type B) Distribution boards.
Developed to ensure optimal performance of SPD technology within Hager distribution boards. 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 1/2 / class I/II SPD for 3 – phase power supply networks.
A type 1 SPD is generally used in the primary board.
This SPD kit fits within the standard distribution board. Line, Neutral and Earth connections are via copper busbar and copper links, minimising SPD conductor losses, maximising the effective performance of the SPD (Up effective).
