Hubbell’s hazardous location unfused disconnect and mechanical

interlock switches are ideal for applications with the presence of

flammable gases or vapors, or ignitable dusts and fibers. They

are also suitable for use in outdoor or indoor damp, wet and dirty

locations or in areas where frequent wash-downs, heavy rain or

water spray routinely occurs. Compact in size to reduce cost

over industry standard sizes, these switches are easy to position

on the wall or piece of equipment. The enclosures are made of

copper-free aluminum and have a polyester/epoxy finish to prevent

corrosion. The high visibility handles can be locked to meet OSHA

lockout/tagout regulations.

Hubbell hazardous location mechanical interlocks and plugs offer

superior safety. The plug and switch are interlocked so that the

switch cannot be turned “ON” without the plug fully inserted, and

the plug cannot be removed when the switch is in the “ON” position.

The switch features a copper-free aluminum construction with
