Fuse for Square D AC Disconnect
General Purpose Fuses- Class RK5 - Time Delay - TR/ TRS

Tri-Onic® SmartSpot® TR fuses now provide an optional visual open fuse indicator. With advanced material technology added to the existing product line the TR current-limiting time-delay fuses are engineered for overcurrent protection of motors and transformers, service entrance equipment, feeder and branch circuits. Tri-Onic fuse's proven time-delay characteristic safely handles harmless starting currents and inrush currents associated with today's motors and transformers.


  • Optional solid-state SmartSpot indicator
  • Time-delay for motor start-ups and transformer inrush currents without nuisance opening
  • Current-limiting for low peak let-thru current
  • Rejection-style design prevents replacement errors (when used with recommended fuse block)
