OVERVIEW

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. TriOnic 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:

• 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
