Hubbell's hazardous location line of non-fused disconnect and mechanical interlock switches are typically used for applications with the presence of flammable gases or vapors, 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.
