TRI-ONIC(R) TR & TRS Time Delay/Class RK5 The industry's Most popular fuse for Motor circuit protection. Tri-onic(R) SmartSpot(R) fuses now provide a visual open fuse indicator. With advanced material technology added to the existing product the 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 proven time delay characteristic safely handles harmless starting currents and inrush currents associated with today's motors and transformers. Features/Benefits 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 blocks) Easy-to-read label for quick 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 HIGHLIGHTS: Applications: Time Delay Current Limiting AC & DC Rated Motor Circuits Mains Feeders Branch Circuits Transformers Service Entrance Equipment General-purpose Protection Ratings Approvals TR AC: 1/10 to 600A 250VAC, 200kA I.R.
