APPLETON UPR Series 63 Amp Plugs and Sockets

U-Line™ Factory Sealed 20 Amp Plugs and Receptacles are used with stationary or portable electrically operated devices in hazardous locations. The ECP Interchanger plug is designed with built-in switch contacts which activate when the plug is twisted into the receptacle. This design allows the ECP plug to fit into standard NEMA 5-20R and 6-20R receptacles, but does not allow standard plugs to be used with the receptacle, ensuring that only safe connections can be made in a hazardous location.

UPRD Series 16 Amp and PRD Series 32, 80 and 125 Amp Plugs and Sockets 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 UPRD 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.

WSR Interlocked Receptacles are designed to prevent electrical arcing when fixed or portable heavy duty equipment is used in adverse environments. Available in 30, 60 and 100 Amp designs, these metallic receptacles feature either a fused or non-fused disconnect and mechanical interlock that prevents plug removal under load. With a plug engaged and the switch in the ON position, the plug can't be removed. With the switch turned OFF and the plug removed, the receptacle can't be energized.
