Description
100A 2.6KV, 5.2KV AND 7.8KV FUSE CUT OUT
Types EU and EUH
Enclosed fused cutouts
Distribution cutouts
Product features
− For outdoor use only
− All live parts enclosed
− Interrupting capacities:
14 kAIC at 2.6 kV to 8 kAIC at 7.8 kV
Description
The ABB EU and EUH fuse cutouts are enclosed in a polymer
concrete housing. They are furnished with a flipper latch
assembly that aids in ejecting larger links. All EU and EUH units
come with a NEMA “A” crossarm mounting bracket and a toggle
screw that can make the operation “non-dropout”.
The EU and EUH fuses are totally enclosed cutouts (no live
parts exposed) for the 2.6 to 7.8 kV range where space is tight.
The fuse tubes for the EU and EUH cutouts are a centerless
ground, glass filament wound, unpainted tube with a horn fiber
liner.
Application
ABB type EU and EUH cutouts provide a complete line of
enclosed polymer concrete cutouts. Only one box is needed
for all voltage ratings. Two doors with fuse tubes and one door
with a disconnect blade all fit in one box. This flexibility offers
a great convenience to utilities who wish to increase the rating
above 50 A or obtain extra heavy duty interrupting capacity in
the future.
− Universal application:
One cutout rated 100 A fused can be used on any system
voltage from 2.4 kV delta to 13.8 kV three-phase grounded
wye.
− Industrial application:
EU and EUH cutouts can be used in replacement
applications in close spaces where there are increased safety
needs.
− Self-contained:
Designed for either dropout or non-dropout operation, EU
and EUH cutouts are field adjustable with a screwdriver.
− Door interchangeability:
All doors and boxes are mechanically interchangeable.
Ratings
EU ratings are normal duty up to 14,000 A single shot. The EUH
heavy duty rating is for higher interrupting currents up to
20,000 A single shot.
Standards and design testing
The EU and EUH enclosed cutouts meet or exceed all
applicable requirements of NEMA SG-2-1986 and ANSI
C37.41.1981 and C37.42-1981 standards.
Standard design features
− The 100 A EU and EUH is furnished with a flipper latch
assembly to aid in ejecting the larger links.
− All units are furnished with a NEMA “A” crossarm mounting
bracket.
− The caps on all tubes and disconnect blades are smooth top
caps.
− The fusible cutouts are furnished with a toggle screw that can
make the operation non-dropout.
− The fuse tubes for the EU and EUH cutouts are a centerless
ground, glass filament wound, unpainted tube with a horn
fiber liner.
− Ratings are on the cutout door for quick viewing.
