DRAWOUT
BREAKER
INTERCHANGEABILITY
In
general,
drarvout
breakers
of
the same
type
and
rating are
interchangeable
in
their equipment
compartments
;
drawout breakers
of
diJf er
ent
fr
ame
sizes are
not
interchangeable.
To
prevent inserting
the wrong
type
breaker
into a
drawout
compartment,
suitable
"rejection
hardware"
is a-ffixed
to each
breaker
and
its compartment.
Figure
4 shows a
typical
rejection
bracket
which aligns
with a
re-
jection
pin
in the
drawout
rail
(Fig.
3). When
the
wrong
type breaker
is inserted
into
a
compartment
the bracket and
pin
do not mate,
preventing the
breaker
from seating
itself
into
the drawout
rails.
There
is one
exception
to the above.
Breakers
of
the same
frame
size having
different short
cir-
cuit ratings
may be interchanged
in
one
direction
onlv:
a.
An
AKR-3OH
can be
inserted into
an
AKR-30
compartment.
b.
An AKR-50H
can be inserted into
an
AKR-50
compartment.
The
rejection
hardware
prevents
the
converse
of
a.
and b.
Figure
2
shows
the rejection
pin
and bracket
combinations
employed.
As determined by its in-
tended breaker
type,
each
drawout c
ompartment
has
its rejection
pin
(or
pins)
installed in one of
three
positions
(A,
B or C
front-to-rear) along
the
slide
rail(s)
.
Referring
to
Views
2 and
5, note that only
the
AKR-30H
and
50H types employtwopins, one
in
each
slide rail.
The other breaker
types use a
single
pin
in the right side
TaiL
AKRU-3O ard 50
fused breakers
use a single bracket,
whereas
a-ll
nonfused breakers
carry two brackets. Use
Fig.

as a
guide
for
determining the
proper
breaker
type(s)
that will be accepted
by any
given
compart-
ment.
