OPERATION
The
circuit

are
designed
for
either
manual
or
electrical
operation
.
Electrically
oper
-
ated
circuit
breakers
may
be
closed
manually
for
maintenance
purposes
by
using
the
maintenance
handle
(
2
,
Fig
.
6
)
to
manually
charge
the
closing
springs
,
and
the
emergency
close lever
(
3
,
Fig
.
6
)
to
close
the
circuit
breaker
.
EMERGENCY
OPERATION
Electrically
operated
circuit
breakers
may
be
closed
manually by
a
removable
maintenance
handle
(
4
,
Fig
.
7
)
for
emergency
operation
.
The
removable
maintenance
handle
(
4
)
is
first
positioned
in
two
slots
in
the
pawl
carrier
{
2
)
.
The
handle
is
then raised and lowered
in
a
~
pumping
motion
until
the
pawl
carrier
(
2
)
no
longer
rotates
the
ratchet wheel
(
1
)
.
The breaker
closing
springs
now
fully
charged
are
ready
for
a
closing
opera
-
tion
which
is
done
by
raising
the
emergency
close
lever
(
6
)
on
the control device
(
5
)
.
The
motor
crank
arm
(
3
)
will
stop
occasionally
in
such
a
position
as
to
prevent
a
full
racking
stroke
.
Should
this
happen
,
the
motor
crank
aim
(
3
)
will
have
to
be
rotated
manually
.
Insert
the
pointed
end
of
the
handle
"
A
"
through
the lower
slot
of
pawl
carrier
(
2
)
and
against
the
motor
crank
arm
(
3
)
.
Hook the
handle
on
slot
of
pawl
carrier
at
"
B
"
and bear down
so
as
to
force
the
motor
crank
arm
(
3
)
to
move
.
The
circuit
breaker
closing
springs
may
then
be
charged
as
described
in
paragraph
above
.
Refer
to
TABLE
II
for
the
possible

,
K
-

,
and
K
-

circuit
breakers
(
K

)
.
These
circuit
breakers
can
be
furnished
as
a
two
-
pole
or
three
-
pole
circuit
breaker
having
either
a
manually
or
electrically
operated
mechanism
.
A
three
-
pole
manually
operated
circuit
breaker
is
shown
on
the
cover
,
and
an
electrically
operated
circuit
breaker
is
shown
in
Fig
.
1
.
Two
-
pole
construction
is
similar
except
that
the
center
pole
is
omitted
.
RACKING
MECHANISM
The
racking
mechanism
may
be
used
to
move
the
circuit
breaker
to
any
one
of
its
three
positions
(
"
CONNECTED
,
"
"
TEST
"
or
"
DISCONNECTED
"
)
.
All
of
these
positions
are
attainable
with
the
cubicle
door
closed
.
The
racking
shutter
(
15
,
Fig
.
1
)
,
which
must
be
lifted
to
gain
access
to
the
rack
-
ing
mechanism
,
is
interlocked
with
the
circuit
breaker
so
that
the
circuit
breaker
contacts
must
be
open
before
the
shutter
may
be
lifted
to
rack
the
circuit
breaker
to
another
position
.
The
circuit
breaker
can
not
be
closed
when
the
shutter
is
open
.
The
circuit
breaker
may
be
padlocked
open
by
means
of
the
locking
hasp
.
This
automatically
locks
the
racking
mechanism
.
With
*
the

)
may
be
pulled
outward
,
accommodat
-
ing
from
one
to
three
padlocks
,
when
the
shutter
is
closed
and
the
circuit
breaker
is
tripped
.
The
^
hutter
can
not
be
lifted
and
the
breaker
contacts
ilhn
not
be
closed
when
the
locking

by
one
or
more
padlocks
.
TRANSPORTATION

STORAGE
It
is
recommended
that
the
circuit
breakers
be
installed
in
their
permanent
location
even
though
they
may
not
be
placed
in
service
for
some
time
.
The
circuit
breaker
may
be
stored
and
locked
in
the
"
DISCONNECTED
"
position
in
its
compart
-
ment
with
the
door
closed
.
Both
the
primary
and
control
separable
contacts
are
disconnected
in
this
position
.
If
the
circuit
breakers
cannot
be
installed
in
their
permanent
location
,
they
can
be
stored
in
their
shipping
cartons
as
protection
against
dust
,
dirt
,
and
damage
.
AUTOMATIC
TRIP
