INTRODUCTION
Circuit
breakers
should
be
installed
in
their
perma
-
nent
location
as
soon
as
possible
.
{
See
Basic
Handling
below
.
)
If
the
breakers
are
not
to
be
placed
in
service
for
some
time
,
it
is
advisable
to
provide
adequate
means
of
protection
.
This
may
be
done
by
keeping
the
breaker
on
its
original
skid
,
covering
with
waterproof
paper
and
sealing
to
prevent
infiltration
of
dirt
.
Where
conditions
of
high
humidity
prevail
,
the
use
of
heaters
is
recom
-
mended
.
These

,
whereas

of
this
bulletin
.
The

can
be
fur
-
nished
with
two

breakers
are
only
fur

can
be
furnished
as

and
are
available
as
manually
or
electrically
operated
,
and
with
electrical

devices
available
in
various
ac

dc
voltage
combinations
.
Many
optional
features
are
also
available
.
An

*
These
instructions
should
be
read
thoroughly
before
handling
,
installing
and
/
or
operating
the
circuit
breaker
.
BASIC
HANDLING
INSTRUCTIONS
Once
the
circuit
breaker
has
been
unbolted
and
re
-
moved
from
its
shipping
skid
,
it
should
be
turned
to
the
upright
position
and
placed
on
a
fiat
surface
to
avoid
damage
to
breaker
parts
.
For
safety
,
all
handling
In
this
position
should
utilize
the
lifting
yoke
(
20
)
shown
in
Figure

CLOSING
SPRING
OPERATION
The
two
dosing
springs
supply
the
power
that
closes
the
drcuit
breaker
and
also
charge
the
two
opening
springs
during
the
dosing
operation
.
The
closing
springs
are
charged
by
a
motor
in
the
electrically
operated
breaker
and
charged
by
hand
in
the
manually
operated
breaker
;
however
,
in
either
type
,
the
springs
are
charged
the
same
amount
and
when
charged
,
the
spring
energy
is
available
to
close
the
breaker
,
thus
referred
to
as
“
stored
energy
/
*
The
dosing
springs
are
normally
charged
when
the
breaker
i s
opened
.
If
charged
after
dosing
,
the
breaker
may
be
opened
and
then
redosed
without
recharging
the
springs
*
In
drawout
breakers
,
the
dosing
springs
are
automatically
dis
-
charged
when
the
breaker
is
moved
from
the
dis
-
connected
to
the
withdrawn
position
(
shown
in
Figure
1
)
.
This
prevents
accidental
discharge
.
Unpack
the
circuit
breakers
as
soon
as
possible
after
receipt
.
If
unpacking
is
delayed
,
difficulty
may
be
experi
-
enced
in
making
a
claim
for
damages
not
evident
upon

Use
care
in
unpacking
in
order
to
avoid
damaging
any
of
the

parts
.
Check
the
contents
of
each
carton
against

of
Gould
*
Information
specifying
the

This
device
is
an
indicator
only
and
does
not
prevent
the
circuit
breaker
reclosing
.
Upon
an
overcurrent
trip
operation
,
the
indicator
protrudes
from
the
front
plate
approximately
%
inch
.
The
automatic
trip
indicator
should
be
reset
after
each
trip
indication
by
pushing
back
into
its
normal
latch
position
.
The
operator
should
investigate
the
cause
of
tripping
before
resetting
the
automatic
trip
indicator
and
subsequent
redosing
the
drcuit
breaker
after
an
outage
which
results
in
an
operation
of
the
indicator
.

)
An
alarm
switch
for
remote
electrical
indication
,
which
is
optional
,
shows
when
automatic
tripping
has
occurred
.
This
is
accomplished
by
adding
a
precision
snap
switch
to
the
automatic
trip
indicator
assembly
.
The
automatic
trip
indicator
actuates
the
roller
on
the
alarm
switch
which
in
turn
causes
a
normally
open
contact
to
dose
and
a
normally
closed
contact
to
open
on
overcurrent
trip
.
The
alarm
contact
is
manually
reset
by
pushing
the
trip
indicator
(

)
back
into
its
normal
position
.

An
additional
device
(
which
is
also
optional
)
may
be
added
to
the
automatic
trip
indicator
assembly
de
-
vice
which
serves
to
mechanically
prevent
recfosing
the
drcuit
breaker
after
an
automatic
trip
operation
.
When
the
trip
indicator
is
pushed
in
the
drcuit
breaker
mechanism
can
then
be
operated
to
close
the
circuit
breaker
contacts
.
Padlocking
Device
(
Figure
1
,
Item
23
}
All
K
-
fine
drcuit
breakers
are
equipped
with
means
of
padlocking
the
drcuit
breaker
mechanism
in
a
trip
-
free
position
.
This
Is
accomplished
by
the
use
of
a
locking
plate
to
maintain
the
manual
trip
button
in
a
tripping
direction
when
the
locking
plate
is
held
for
-
ward
by
one
or
more
padlocks
.
To
obtain
the
condi
-
tion
for
padlocking
the
drcuit
breaker
in
the
open
position
,
the
manual
trip
button
is
pushed
inward
.
Then
the
padlock
plate
is
pulled
out
and
the
padlock
in
-
serted
Into
the
vertical
slot
.
In
this
position
,
the
mechan
-
ism
is
maintained
trip
free
and
the
contact
arm
cannot
be
moved
to
the
dosed
position
.
On
circuit
breakers
equipped
with
drawout
mechanism
,
the
padlocking
device
is
associated
with
the
drawout
interlocking
mechanism
so
that
the
drcuit
breaker
can
-
not
be
moved
from
any
of
its
three
basic
drawout
posi
-
tions
of
“
CONNECTED

“

”
or
''
DISCONNECTED
with
the
padlocking
in
effect
.
Closing
Spring
Charge
Indicator
(
Bgure
1
,
Item
14
]
Under
normal
operating
conditions
,
the
closing
springs
are
automatically
charged
after
each
tripping
operation
.
However
,
there
are
occasions
when
the
springs
will
be
in
a
discharged
state
.
Therefore
,
it
is
desirable
that
means
be
available
to
indicate
the
charged
or
uncharged
condition
of
the
closing
springs
.
This
is
accomplished
by
a
visual
indicator
seen
through
an
aperture
in
the
escutcheon
plate
.
The
indicator
is
marked
“
CHARGED
”
and
“

ESCUTCHEON
OPERATING
FEATURES
Manually

.
This
escutcheon
provides
a
central
area
for
the

which
are
mounted
directly
on

breaker
.
The

PERIODIC
MAINTENANCE
INSPECTION
The
safety
and
successful
functioning
of
the
con
-
nected
apparatus
depends
upon
the
proper
operation
of
the
drcuit
breaker
.
Therefore
,
it
is
recommended
that
a
maintenance
program
be
established
that
will
pro
-
vide
for
a
periodic
inspection
of
the
drcuit
breaker
after
250
no
load
or

cvrrent
switching
operations
.
If
250
operations
are
not
completed
in
the
first
year
of
service
,
the
drcuit
breakers
should
be
inspected
re

The
drcuit
breaker
should
also
be
inspected
after
a
short
drcuit
or
severe
overload

,
regardless
of

or
number
of
operations
.
Where

,
it
must
be
assumed
that
these
conditions
were
considered
at
the
time
of

;
that
the
equipment
supplied
was
designed
for
the
special
application
;
and
that
an

has
been
developed
.
These
main
-
<
^
ance
instructions
only
cover
drcuit
breakers
used
yfiffider
the
standard
usual
service
conditions
.
The
inspection
should
include
opening
and
closing
the
circuit
breaker
electrically
and
manually
.
The

should
be
visually
inspected
for
loose

A
moderate
amount
