Abstract
Abstract A circuit protection assembly for protecting telephone communication related equipment includes a two-piece interfitting housing, a printed circuit board sub-assembly, an exposed side connector device, and a protected side connector device. The printed circuit board is mounted internally inside the housing and is adapted to receive any number of circuit protector combinations of overvoltage, overcurrent and line-status devices. Each of the exposed side and protected side connector devices can be one of several different types of connector so as to provide versatile mechanical connections to the circuit protectors.
