The Edco OPX Series surge protectors are specifically designed for medium exposure applications. Thus, the protectors can be used on pairs inside a building or leaving the building in conduit up to 500 feet. These protections are intended to be used in conjunction with the Edco MGB Ground Rail and a standard MI-50 Punch Down Block.

The Edco OPX Series offers several distinct advantages over other current technologies. Among the advantages are low cost, no series resistance, and durable, solid-state construction.
