TR-R - Class RK5 - Time-Delay

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
