BUSSMANN
SERIES
15.5kV E-Rated medium voltage fuses for feeder
circuit, switchgear and transformer protection
Features and benefits
•
Current-limiting E-Rated medium voltage
fuses are defined by their melting time-current
characteristic that permit their electrical
interchangeability with other fuses of the same
E Rating.
E-Rated fuses must have a defined current
response time specified by ANSI C37
.46.
E-Rated fuse of 100 amps and below must
melt in 300 seconds at an RMS current within
the range of 200% to 240% of the fuse’s
nameplate current rating. E-Rated fuses greater
than 100 amps must melt in 600 seconds at an
RMS current within the range of 220% to 264%
of the fuse’s nameplate current rating.
E-Rated fuses are physically dimensioned for
easy installation in existing hardware.
Current-limiting fuses provide positive
interruption even on low fault currents. The
fuse limits the magnitude of electromechanical
stresses in the protected apparatus.
Constructions available in ferrule, bolt-on
and clip-lock, and specialty mount fuses for
AMPGARD motor starters
Outdoor rating available on select catalog
numbers (requires installation in a suitable
enclosure).
Open fuse indicator easily integrates
into automation schemes and speeds
troubleshooting by providing a positive visual
indication of fuse operation.
Optional remote contact signaling microswitch
available.
50/60Hz operating frequency for worldwide
application.
Mountings are available in disconnect and non-
disconnect versions with porcelain or glass poly-
ester insulators.
Live parts and end fittings available.
