SMISSLINE TP plug-in system
Surge arrester

The type 2 surge arresters in the QuickSafe product range are suitable for protecting electrical
low voltage systems and terminals in the 240/415 V system. The devices can be used as type 2
surge arresters within the scope of the lightning protection zone concept at zone tran sition
0B–1 and higher. The high nominal discharge capability of 20 kA makes it possible for the equip-
ment to have a longer service life in comparison to the minimum requirements of the standard.
The devices consist of a basic unit and pluggable protection modules, which can be removed
extremely easily to carry out insulation measurement. They are fully compatible with SMISSLINE
installation devices and the surge arresters in the ABB System pro M model series. The surge ar-
resters are tested as type 2 arresters in accordance with the EN/IEC 61643-11 test standard.
