OVR range: Type 1 + 2

Protection against overvoltages and impulse currents (such as switching and
lighting surges). Limit overvoltage to a level acceptable by the equipment to
be protected and divert surge currents
Type 1 + 2 : Surge arrester designed to run-off energy caused by an
overvoltage comparable to that of a direct lighting (10/350 wave)
Class 1 and indirect lighting (8/20 wave) Class II
: Surge arresters installed at main switch board
