HOFFMAN Hazardous Location Window Kits

U-Line™ ECS Factory Sealed 15 and 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.

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.
