The 1463G1 is a mounting clamp designed for fastening 2 or 4-pole Powerpole PP75 connector blocks to flat surfaces such as sheet metal panels and printed circuit boards. This accessory enables secure mechanical attachment of complete square connector blocks without requiring the housing to be removed from the board side. The clamp works in conjunction with the PP75 series housings, which support wire sizes from #16 AWG (1.3 mm²) to #6 AWG (13.3 mm²) with power capabilities up to 120 amps per pole. The mounting clamp is particularly useful in applications requiring robust panel-mounted connector assemblies, such as power distribution systems, industrial control panels, and modular power systems where reliable mechanical retention is essential.
