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/BENEFIT S:

•

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
