HOFFMAN Hazardous Location Heaters

JBR Series 30 and 60 Amp Switched Receptacles are heavy duty flanged and bolted enclosures that provide exceptional safety in hazardous locations. The terminal block in the mounting box makes wiring easy, and a special polarization option prevents insertion of a plug into a receptacle wired for a different voltage. Dead front interlocked construction requires the plug to be fully inserted before the switch can be placed in the ON position.

EBR 30, 60, 100 and 150 Amp Series Receptacles incorporate your choice of an interlocked circuit breaker or disconnect switch along with explosionproof and dust-ignitionproof protection. The interlocked circuit breaker provides connect and disconnect operating functions as well as short circuit and thermal time delay overload protection, safeguarding valuable equipment against expensive damage. The interlocked disconnect switch provides safe connection and disconnection.

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.
