CODE c
(AKD-6
SWITCHGEAR)
(Fig.
s)
These
breakers
employ the same
drawout arrangement as
the Code A models
described on
page
7. Their drawout
operation and breaker
insertion/removal
procedures
are
identical,
but
they
differ significantly
in
other aspects.
As
indicated
in Table
1,
the AKR-(
)C-75
is a 32004 Ac
frame
size compared
to the 3000A
A model. The
AKR-(
)C-100
is
narrower than AKR-(
)A-100
(25
versus 33 inches).
All C
models
employ
finger-type
primary
disconnects
instead
of
the
tubular
studs of
the A types
per
fig.
2.
C breakers cannot be employed as
replacements for
A
types
due
to their width
and
primary
disconnect
configura-
tion.
