JK102SPD
Product Description
A Surge protection device (SPD) kit specically 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 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 ts 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 veried.
