Flameproof Plugs & Sockets

Product Category: Flameproof Plugs & Sockets | ATEX Certified | Zone 1 & Zone 2 Hazardous Areas

PRD Series 16, 32, 80 and 125 Amp Flameproof Plugs and Sockets manufactured by Appleton ATX are designed for hazardous areas where weatherproof and robust equipment is required. These flameproof plugs and sockets are certified for hazardous areas Zones 1, 2, 21 and 22. The PRD series of plug and socket assemblies provides safe, reliable power for portable or stationary electrical equipment such as lighting and heating systems, conveyors, motor starters, air-conditioning appliances, compressors and pumps.

The 16 Amp plug has a flameproof seal with cylindrical spigot joint, automatic disconnection of the poles once the plug is removed from the socket outlet by the patented dual safety device and the cover can be padlocked.

PRD 32 Amp flameproof seal also features a cylindrical spigot joint, with a mechanical interlocking device ensures disconnection within the flameproof chamber before the plug is removed. The plug cannot be removed when energized.

80 Amp and 125 Amp plugs feature an interlocking mechanical device which prevents the switch from closing until the plug is fully inserted into the wall socket or being removed until the switch is off. Socket outlet supplied with a load break isolating switch. The switch handle can be padlocked.
