TRS-R - Class RK5 - Time-Delay

Approvals & Standards
UL listed to standard 248-12 File E2137
CSA certified to standard C22.2 no. 248.12
DC listed to UL standard 248 TRS only

Tri-Onic TRS-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 TRS-R safely handle harmless starting currents and inrush currents associated with today's motors and transformers.

Key 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
