Surge arrester type PROXAR IVN AC has very big energy withstand. It can absorb big charge of lighning overvoltage. It is recommended for installations, where there are large loads of surges or they are permement. PROXAR IVN AC has got very efficient protection characteristics, thanks to it, the protection of other equipment is very good. This arrestes is mainly recommended for big capacitor banks, generators, main busbars and main switchgears in industrial objects. The range of rated voltages is from 1 kV till 9kV. Other rated voltaged are available on the request.
