Tri-Onic TR-R current-limiting time-delay fuses are engineered for overcurrent protection of motors, transformers, service entrance equipment, feeders and branch-circuits. The time-delay characteristics of the TR-R safely handle harmless starting currents and inrush currents associated with today’s motors and transformers.


  • OPotential Transformerional 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)
