THE INDUSTRY’S MOST POPULAR FUSE FOR
MOTOR CIRCUIT PROTECTION.
Tri-onic® SmartSpot® 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.
