fuses now provide a visual
open fuse indicator. With advanced material technol-
ogy added to the existing product the 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 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
➤
High-grade
silica filler ensures fast arc quenching and
high current limitation
