APPLETON UPR Series 16 Amp Plugs and Sockets

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.

U-Line™ Contender™ Factory Sealed 20 Amp Plugs and Receptacles feature a dead front design making them ideal for use with electrical equipment in hazardous locations. The neoprene gasket in the throat of the receptacle seals against the plug or the spring-loaded cover to seal out water, dust and corrosive compounds. Although U-Line plugs can be used with ordinary receptacles, U-Line receptacles are designed so that they can't be energized by an ordinary plug.

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.

ASR Nonmetallic Interlocked Receptacles prevent electrical arcing when used with fixed or portable heavy duty equipment. Available in 30 and 60 Amp designs, they feature an ON/OFF switch and an enclosed mechanical interlock that prevents plug removal under load. Fused and non-fused models are available, with both designs featuring self-cleaning contacts and a seamless silicone gasket that minimize the need for maintenance. They are ideal for use in damp and corrosive environments.
