TR-R & TRS-R Time Delay/Class RK5 UL/CSA LISTED POWER FUSES THE INDUSTRY’S MOST POPULAR FUSE FOR MOTOR CIRCUIT PROTECTION With advanced material technology added to the existing product, the Tri-Onic® TR and TRS 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. Now available with optional SmartSpot® blown fuse indication technology. FEATURES/BENEFITS:

  • 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 RATINGS: TR-R
  • Volts: 250VAC; 160VDC (3-30A; 450-600A)
