Abb offers a wide range of surge protection devices specially designed and tested to live up to the very specific applications, such as for cable and cable-sheath protection as well as for contact protection in railroad installations. Most of the arresters incorporate the latest metal - oxide technology [both ac and dc] and thus offer the best possible protection margin. Salient features are as follows:
1 low residual voltage
2 long protection distance
3 high energy input capacity
4 stable u-i characteristics even after multiple strokes
5 proof against ageing
6 explosion and shatter-resistant design
7 pollution resistant and uv-stable
8 housing resistant to rough handling
9 maintenance free
10 stable against shock and vibration
11 high mechanical resistance
