APPLETON UPR Series 16 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.

FSQC 30, 60 and 100 Amp Series Receptacles incorporate an interlocked disconnect switch for added safety in hazardous environments. The explosionproof and dust-ignitionproof FSQC is designed for use with Powertite™ plugs. Simply insert the plug and rotate the receptacle face to the ON position to lock it in place and energize the receptacle. For installations where different line voltages are used, a special polarization option prevents plug insertion into a receptacle wired for a different voltage.

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.
