HOFFMAN Hazardous Location Heaters

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.
