ABILITY
OF
DRAWOUT
BREAKERS
In
general
,
drawout breakers
of
the
same
type
and
rating
are
interchangeable
in
their
equipment
compartments
;
drawout
breakers
of different
frame
sizes
or
short
circuit
ratings
are
intentionally
made
non
-
interchangeable
.
To
prevent
inserting
the
wrong
type
breaker
into
a
drawout
compartment
,
unique
“
rejection
hardware
”
is
affixed
to
each breaker and its
compart
-
ment
.
Figure
9
shows
a
typical
breaker
-
mounted
rejection
bracket which
aligns
with
a
rejection
pin
in
the drawout rail
(
Fig
.
10
)
.
When
the
wrong
type
breaker is inserted
into
a
compart
-
ment
,
the
bracket
and
pin
do
not
mate
,
preventing
the breaker
from
seating
itself
into the rail slots
.
There is
one
exception
to
the above
.
Breakers
of
the
same
frame
size
having
different
short circuit
ratings
may
be
interchanged
in
one
direction
only
.

As
dictated
by
its intended
breaker
type
,
each

installed
in

The
AKRU

fused
breakers
employ
a
single
bracket
,
while
all
non

fused
breakers
carry
two
brackets
.
Note
that
the
rejection
hardware
is
identical
for
both
