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/tag out regulations.
