• Low amperage, E-Rated medium voltage fuses are general
purpose current limiting fuses.
• The E rating defines the melting-time-current characteristic of
the fuse and permits electrical interchangeability of fuses
with the same E Rating.
• For a general purpose fuse to have an E Rating the following
condition must be met:
The current responsive element shall melt in 300 seconds at
a rms current within the range of 200% to 240% of the con-
tinuous current rating of the fuse, fuse refill, or link. (For
fuses rated 100E or less)(ANSI C37.46).
• Bussmann low amperage, E-Rated fuses are designed to
provide primary protection for potential, small service, and
control transformers.
• These fuses offer a high level of fault current interruption in a
self-contained non-venting package which can be mounted
indoors or in an enclosure.
