Mechanism Features

Component or Function Over-Toggle Mechanism Stored Energy Mechanism
Switch Function Manually operated closing and opening independent of the speed of the user
  • Springs pre-charged without closing the switch in two steps providing stored energy within the mechanism
  • Switch opened and closed by the stored energy independent of the user speed of the pushbuttons
  • Automatic fuse tripping with Fuselogic system
Grounding Switch
  • Manually operated closing independent of the speed of the
  • Operating energy is provided by a compressed spring
  • Individual operator dependent opening
  • Manually operated closing independent of the speed of the user
  • Operating energy is provided by a compressed spring
  • Individual operator dependent opening
Auxiliary Contacts
  • Switch Position 3 N.O. and 3 N.C. and Grounding Switch 1 N.O. and 1 N.C.
  • Switch Position 3 N.O. and 3 N.C. and Grounding Switch 1 N.O. and 1 N.C.
Mechanical Indication Blown fuse indicator if switch equipped with fuses Blown fuse indicator if switch equipped with fuses
Motor Operator All circuits must be the same control voltage for motor operator mechanism. All circuits must be the same control voltage for motor operator mechanism.
Close Coil — Yes
Trip Coil — Yes
Operating Time: 100 milliseconds
Shunt Trip Options —
  • Manually operated locally at the switch/no coils/no motor
  • Manually charged springs with open coil (remote or local trip)
  • Motor operated with open and close coils; permits local and remote control of spring charging, close, and trip
Operation Counter Yes Yes
