Overvoltage protection arrangement for information and telecommunication technology
The invention relates to an overvoltage protection arrangement for information and telecommunication technology, consisting of a housing with means formed on the housing base for mounting top-hat rails, overvoltage protection elements which can be found in the housing, electric connection means, and at least one circuit board as a wiring support for the overvoltage protection elements. When viewed laterally, the housing is designed approximately in the shape of a T standing on its head and has a beam-shaped main part with a protruding head part, wherein the electric connection means can be accessed and actuated via the upper face of the beam-shaped main part. A first and second circuit board are located on a respective inner face of the lateral walls of the housing in a mutually spaced manner, and the electric connection means in the form of electric connection terminals, connection sockets, and/or plugs for example are arranged in the spacing between the first and second circuit board such that first connection means can be accessed on the horizontal plane of the beam-shaped main part and second connection means can be accessed on the vertical plane of the beam-shaped main part. The flat shape of the circuit board corresponds to the T shape of the housing or approximates the shape of the housing.
