      Benefits

      Reliable performance

      Long term durability

      • Mechanical endurance of F series is guaranteed to exceed three times the NEMA requirements
      • Enclosed operating mechanism design reduces the amount of dust and other contaminants that shorten the mechanism’s operating life.
      • More current carrying copper
      • Result -- switches operate cooler
      • Cooler temperatures -- longer life
      • Galvanized Steel with E-Coat on all NEMA 3R Enclosure
      • Meets or exceeds NEMA KS1

      Efficient Installation

      • Tangential knockouts, where provided, lessen the need for conduit offset bends
      • Generous wire bending space
      • Factory or field installed Insulated, bonded solid neutral and equipment ground assemblies
      • Wire terminations suitable for aluminum or copper conductors
      • Field installable rainproof B Hubs
      • Field installable watertight H Hub

      Operation Safety Features

      • Two tone color handle clearly shows switch's status
      • Red "ON"
      • Black "OFF"
      • Dual Cover Interlock
      • The switches includes an oversized arc suppressor, a key feature in the ability of the switch to break the load by effectively attenuating the arc for a clean interruption
      • Switches are stocked and ready for delivery from our warehouses
