ABSTRACT:
A combined overvoltage station protector apparatus with a maintenance termination and a half ringer circuit arrangement combined with an overvoltage surge arrester mounted in a single housing includes a hollow housing divided into a first section and a second section, with each having a top surface and an open bottom. A pair of input line terminals and a ground terminal are fixed to the top surface and extend inside the hollow housing first section. A pair of output line terminals are affixed in the top surface of the second section and extend within the hollow housing. A printed circuit board, disposed within the second section of the housing provides for interconnecting the electrical circuit components, which form the maintenance termination and the half ringer circuit arrangement. A housing assembly, disposed within the hollow housing first section, is connected to the housing ground terminal and is adapted to removably receive a surge arrester therein. The surge arrester is a three-terminal device, having at least a pair of electrode terminals and a ground terminal, which is in electrically conductive contact with the housing ground terminal. Each one of the electrode terminals is in electrically conductive contact with one of the pair of line terminals.
