Features and benefits
• Low amp, current-limiting E-Rated PT
medium voltage fuses are general purpose
fuses defined by their melting time-current
characteristic that permit their electrical
interchangeability with other fuses of the
same E Rating.
• E-Rated general purpose fuses must have
a current responsive element that will melt
in 300 seconds at an RMS current within
the range of 200% to 240% of the fuse’s
nameplate current rating, fuse refill, or link
per ANSI C37.46 for fuses rated 100E or less.
• PT fuses are physically dimensioned for easy
installation in existing hardware.
• Space saving size eases design
considerations for new installations.
• Current-limiting fuses provide positive
interruption even on low fault currents.
The fuse limits the magnitude of
electromechanical stresses in the protected
apparatus.
• These fuses are in a self-contained, non-
venting package for installation indoors or
outdoors in an enclosure.
• Available in indicating and non-indicating
versions.
• Open fuse indicator speeds troubleshooting
by providing a positive visual indication of
fuse operation.
Typical applications:
• Primary protection of:
• Medium voltage potential transformers
• Small medium voltage service
transformers
• Small medium voltage control
transformers.
