When
the
breaker
is
tripped
by
an
overload
device
,
auxiliary
shaft
(
9
)
rotates
counterclockwise
causing
latch
(
8
)
to
move
off
of
latch
arm
(
5
)
.
The
breaker
opens
causing
prop
(
3
)
to
ro
-
tate
clockwise
allowing
switch
(
2
)
to
close
.
The
switch
then
rotates
latch
arm
(
5
)
,
which
,
in
turn
allows
catch
(
11
)
to
move
downward
thereby
locking
latch
arm
(
5
)
in
the
rotated
position
.
When
in
the
rotated
position
the
latch
arm
keeps
the
trip
shaft
and
prop
(
3
)
in
the
trip
-
free
position
,
thus
keeping
the
breaker
from
being
closed
until
the
lockout
mechanism
is
reset
by
means
of
reset
button
(
1
)
.
When
the
switch
is
closed
its
contacts
can
be
used
to
sound
an
alarm
.
If
the
breaker
is
tripped
by
any
device
other
than
an
overload
device
,
latch
(
8
)
keeps
latch
arm
(
5
)
from
rotating
and
therefore
stops
the
bell
alarm
and
lockout
de
-
vice
mechanism
from
operating
.

.
The
lockout
adjusting
screw
(
3
)
should
be
adjusted
so
that
it
engages
the
lockout
trip
paddle
(
5
)
and
dis
-
places
the
trip
shaft
(
6
)
when
the
breaker
is
opened
.
This
assures
that
the
breaker
is
locked
open
until
the
device
is
reset
as
described
