DRAWOUT
MECHANISM
(
FIG
.
43
)
Drawout
breakers
are
furnished
with
a
drawout
mechanism
which
facilitates
the
inserting
and
withdrawing
of
the
breaker
from
its
enclosure
.
It
provides
a
suitable
menas
of
forcing
the
breaker
through
the
part
of
the
inserting
and
withdrawal
operations
when
the
stationary
and
movable
halves
of
the
disconnects
engage
and
disengage
.
For
complete

inserting
and
withdrawing
the
breaker

furnished
with
the
breaker
.
The
drawout
mechanism
is
equipped
with
a
drawout
trip
interlock
which
prevents
a
racking
operation
from
being
performed
when
the
breaker
is
closed
.
Inserting
the
breaker
into
the
housing
causes
the
racking
pins
on
the
housing
to
engage
the
semi
-
circular
slot
in
the
racking
cam
(
4
)
.
In
this
position
the
breaker
is
ready
to
be
fully
racked
-
in
by
operating
the
racking
handle
(
1
)
.
The
first
upward
stroke
of
the
racking
handle
causes
the
racking
pin
on
the
housing
to
engage
the
trip
interlock
link
and
pin
assembly
(
2
,
3
)
,
rotating
the
link
(

)
and
causing
the
pin
(
3
)
to
move
upward
against
the
adjusting
screw
on
the
interlock
trip
paddle
.
This
trips
the
breaker
and
holds
it
trip
-
free
during
the
entire
racking
opera
-
tion
.
The
fifth
and
final
stroke
of
the
racking
handle
releases
the
trip
interlock
and
allows
the
breaker
to
be
closed
,
since
the
breaker
is
now
fully
racked
