ABSTRACT:
A voltage protector and grounding bar arrangement is provided for use with a telephone terminal block having at least two rows of terminals which are spaced apart from each other so as to define an elongated channel therebetween. A housing has incorporated therein a voltage suppressor, terminal contacts for mating with the terminals of the terminal block, and a ground contact for mating with a grounding bar disposed within the channel of the terminal block. Plug-in carrier devices are adapted to be mounted in a plug-in manner upon the housing, and the carrier devices may comprise fuse-type current limiting devices, positive-temperature-coefficient (PTC) current limiting devices, or bridging clips. The housing may accommodate a single plug-in carrier device, or dual plug-in carrier devices whereby protection is afforded to the circuit-to-be-protected in a multitude of directions.
