Description

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.
  • Time-delay
  • Current-limiting
  • AC & DC rated
  • Optional solid state SmartSpot blown fuse 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 blocks)
  • Easy-to-read label for quick brand recognition and replacement
  • Metal-embossed date and catalog number for traceability and lasting identification
  • Fiberglass body provides dimensional stability in harsh industrial settings
  • High-grade silica filler ensures fast arc quenching and high current limitation
