Features, Benefits, and Functions

  • Ample wire bending space provides for easier installation
  • Visible double-break quick- make, quick-break rotary blade Two points of contact provide a positive open and close, easier operation, and also help prevent contact burning for longer contact life
  • Triple padlocking capability. Personnel safety feature since the large hasp can accommodate up to three 3/8-inch (9.5 mm) shank locks. Clearly visible handle. The position (ON or OFF) can be clearly seen from a distance.
  • Deionizing arc chutes; arc chutes confine and suppress the arcs produced by opening contacts under load
  • Additional locking capability; cabinet door can be further padlocked at the top and bottom
  • A clear line shield (provided on fusible double-throw) protects against accidental contact with energized parts. Probe holes enable the user to test if the line side is energized without removing the shield
  • Tangential knockouts on sides, top, and bottom. Enables any size of conduit to be mounted close to the wall, providing for cable installation closer to the wall and a neat appearance
