Ferraz TR30R Fuse

Ferraz TR30R Fuse, TR, 30A, 250VAC, for Square D AC Disconnect

American Power Fuses
TRI-ONIC®
TR and TRS (Class RK5 TD)

Tri-onic® SmartSpot® fuses now provide an optional visual open fuse indicator. With advanced material technology added to the existing product line the TR 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.

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
• Brass end-caps (blade-style) for cooler operation and superior performance
• High-grade silica filler ensures fast arc quenching and high current limitation
