125A Surge Protection Kit Type II
Type 2 Surge Protection Kit for Hager 125A TP&N Distribution Boards to aid compliance with 18th Edition BS 7671.
A Surge protection device (SPD) kit specifically developed for Hager standard TPN (Type B) Distribution boards. This device protects electrical and electronic equipment against transients and the switching of transformers, lighting and motors. 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 2 / class II SPD for 3 phase power supply networks. A type 2 SPD is generally used in sub-distribution boards, downstream of the primary board which may incorporate a Type 1 SPD.
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). SPD performance coordination with upstream Type 1 SPD within Hager MCCB Panelboards has been verified.
