TR-R & TRS-R
Time Delay/Class RK5
UL/CSA LISTED POWER FUSES
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. Tri-Onic 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:
• 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
