Features

  • When the switch is in the completely open position, the switchblade hangs below the polymer housing, providing a positive indication that the switch is open.
  • All live parts are protected by the closed-door design, whether the blade is in the open or closed position.
  • A door detent is provided which securely holds the door open or closed, to allow for safe switch operation.
  • A quick-break mechanism on both the 400- and 600-amp models effectively interrupts transformer-magnetizing current.
