DRAWOUT
BREAKERS
GENERAL
Drawout
breakers
are
manufactured
in
three
different
styles
identified
by
mounting
code letters
A
,
B
and
D
.
Code
A
break
-
ers are
employed
in AKD
-

switchgear
and
feature
closed
-

.
Code
B
breakers
provide
an
alternate
closed
-
door drawout
arrangement
with
the
stationary
element
furnished
as a
preassembled
“
substructure
”
.
Code
D
break
-
ers are
employed
in AKD
-
8
or
substructure
type
gear
and
feature
closed door drawout
.
The construction and
operation
of
each
of
these drawout
styles
is covered under
respective
headings
in
the
following
text
.
As
a
general
rule
,
breakers
of
the
same
drawout
type
,
voltage rating
and
ampere
frame
size
are
physically
inter
-
changeable
.
However
,
to
be
electrically interchangeable
with
respect
to
secondary
and
control
circuits
,
they
must
have
duplicate
wiring
.
The
degree
of
interchangeability
and
the
mechanisms
for
controlling
it
are
discussed
separately
on
page
(
14
)
-
Mote
:
The
three drawout
types
are
mutually
nonin
-
terchangeable
;
before
insertion
is
attempted
,
verify
that
the
breaker
model
matches its
intended
com
-
partment
.
LOCATION
In
choosing
a
location
for
the installation
of
these breakers
there
are
two
factors
to
be considered
.
The
first
is
the
location
’
s
environmental
impact
on
the breaker
.
Much better
perfor
-
mance
and
longer
life
can
be
expected
if
the
area
is clean
,
dry
,
dust
-
free
and well ventilated
.
The
second is convenience
for
operation
and
maintenance
.
The breaker should be
easily
accessible
to
the
operator
and
there should
be
sufficient
space
available
for
maintenance
work
.
STATIONARY BREAKERS
These breakers
are
designed
for
mounting
in
a
switchboard
or
enclosure
designed
and
constructed
by
others
.
Mounting
consists
of
bolting
the breaker
frame
to
a
supporting
structure
within
the switchboard
or
enclosure
,
connecting
the
power
buses
or
cables
,
and
making
any
necessary
control
connec
-
tions
.
The
front
cover
of
the breaker enclosure
may
be
a
hinged
door
or a
plate
bolted
to
the
panel
,
including
a
cut
-
out
opening
through
which the
front
escutcheon
of
the breaker
can
protrude
.
The
surface
on
which
the breaker is
mounted
must
be
flat
to
avoid internal distortion
of
the breaker
.
The
supporting
struc
-
ture must
be
rigid enough
to
avoid
any
possibility
of
the breaker
studs
supporting
the
weight
of
the
breaker
.
Minimum
cutout
dimensions
as
given by
the
appropriate
outline
drawing
must
be
maintained
to
provide adequate
electrical clearance
.
Con
-
necting
bus and
cables
must
be
rigidly
supported
to
prevent
undue
stress
on
the breaker terminals
.
The outline
drawings
in
Table

basic
dimensional
information for

pins
on
each side
of
its
frame
;
these
engage
slots
in
telescoping
slide
rails
(
tracks
)
mounted
to
each sidewall
of
the breaker
compartment
.
The door
of
the
compartment
is
hung
on
a
telescoping
inner
housing
also attached
to
the
movable tracks
.
These elements
are
arranged
so
that
the
door
moves
in
unison
with
the breaker between
the
CONNECTED
and
DISCON
-
NECTED
positions
,
allowing
the
breaker
to
be

work
serving
as
the
stationary
receptacle
for
a
drawout
breaker
.
Featuring
closed

door
type
drawout
operation
,
it
is
designed
for
convenient
mounting
in
individual
breaker
compartments
of
drawout
switchgear
equipments
.
It
provides
means
for
making
the
primary
and
secondary
connections
to
the
removable
breaker
element
and
is
factory
aligned
.
All
AKR
B

are
equipped
with
a
“
deep
”
escutcheon
instead
of
the
standard
escutcheon
employed
on
the
A

models
.
This
configuration
allows
the
breaker
to
be
racked
between
the
CONNECTED
and
DISCONNECTED
positions
with
the
door
closed
.
The
door
is
hung
on
the
compartment
(
not

)
and
does
not
move
with
the
breaker
as
it
does
in
the

;
the
same
support
method
(

)
is
also
used
.

A
OPERATION
GENERAL
ELECTRICAL
CLOSING
A
breaker
may
be
equipped
to
operate
either
manually
or
electrically
.
Both
types
of
operation
result
in
the
same
fast
-
closing
movement
as
far
as
the
contact
action
is
concerned
.
The
variation
is
in
the
way
energy
is
stored
in
the
closing
spring
,
and
how
it
is
released
.
On
electrically
operated
breakers
the
closing
springs
are
charged
by
a
gear
motor
.
With
the
springs
discharged
,
voltage
applied
to
the
control
circuit
will
energize
the
motor
through
the
"
G
”
switch
contacts
—
see
fig
.

.
The
motor
,
through
the
gear
reduction
output
crank
,
compresses
the
closing
springs
until
they
are
fully
charged
.
As

relay
.
At
the
same
time
,
a
mechanical
prop
is
positioned
to
prevent
the
discharge
of
the
fully
charged
closing
spring
.
With
the
closing
spring
propped
fully
-
charged
,
the
breaker
is
ready
for
closing
.
This
may
be
accomplished
electrically
by
depressing
the
closing
switch
on
the
breaker
(
if
so
equipped
)
or
by
a
remote
closing
switch
.
Operation
of
the
closing
switch
energizes
the
“
X
”
relay
,
which
in
turn
energizes
the
closing
solenoid
.
This
removes
the
prop
,
releasing
the
closing
springs
to
close
the
breaker
.
As
the
closing
relay
is
energized
,
it
energizes
anti
-
pump
relay
“
W
”
.
If
the
closing
switch
is
maintained
closed
,
the
anti
-
pump
relay
will
remain
picked
-
up
to
prevent
a
second
closing
operation
on
the
breaker
in
the
event
it
is
tripped
open
automatically
.
The
closing
impulse
must
be
released
and
reapplied
before
a
second
closing
operation
can
occur
.
MANUAL
CLOSING
Manually
operated
AKR
breakers
are
constructed
with
front
-
mounted
handles
.
Handle
operation
resets
the
mechanism
and
fully
charges
the
closing
spring
.
A
complete
charge
is
accomplished
in
either
cranking
the
handle
through
one
cycle
(
135
-
degree
swing
)
or
three
cycles
(
50
-
degree
swing
)
.
The
CLOSE
button
,
mounted
on
the
escutcheon
,
is
used
to
close
the
breaker
contacts
and
the
TRIP
button
to
open
them
.
If
equipped
with
a
closing
solenoid
,
a
manual
breaker
may
be
closed
remotely
by
a
control
switch
or
relay
.
Before
this
can
be
done
,
however
,
the
closing
spring
has
to
be
charged
by
hand
.
The
closing
solenoid
is
an
optional
accessory
and
is
not
supplied
unless
specified
in
the
breaker
order

A
TRIPPING
In
the closed
position
,
the breaker
’
s
movable
contacts
are
held
in
by
a
toggle
linkage
.
The
breaker is
tripped
open
by
displacing
a
mechanism
latch which allows
this
toggle linkage
to
collapse
.
The
trip
latch is
rigidly
fastened
to
a
horizontal
trip
shaft
running
from left
to
right through
the breaker
.
In
turn
,
the
tripshaftcarries
paddles
actuated
by
the
manual
trip
button and
the various
other
trip
devices
—
overcurrent
,
reverse
current
,
shunt
trip
,
undervoltage
,
open
fuse
lockout
.
Viewing
the
breaker
from
the
right
,
rotating
the
trip
shaft
counterclockwise
trips
the breaker
;
clockwise
movement resets
the mechanism
latch
.
In
addition
to
tripping
the
breaker
,
some
devices
hold the
breaker
trip
free
,
i
.
e
.
,
prevent
the
contacts
from
closing
even
though
a
closing
impulse
is
applied
to
the mechanism
.
Such
devices
are
the
undervoltage
,
bell alarm and
lockout
,
electric
lockout
,
open
fuse
lockout
,
and
the
key
operated
locks
.
These
devices and
the drawout mechanism
interlocks
must
be
in
the
reset
position
before
the breaker
can
be closed
.
FUSED
BREAKERS
The
AKRU
-
30
/
50
type
breakers
employ
current
limiting
fused
mounted
integrally
with
the breaker
(
see
Fig
.
9
)
.
Included
is
an
open
fuse
lockout device
(
OFLO
)
to
'
prevent
single
-
phasing
in
the
event
only
one
fuse
blows
.
across
its
corresponding
fuse
.
The
arc
voltage
generated
by
a
blown
fuse
activates
its
OFLO
shunt
trip
coil
,
thereby
tripping
the breaker
and
preventing
single
phase
power
from
being
supplied
to
the load
.
An
indicator
on
the
OFLO
device
signals
which
fuse
is blown
.
The
breaker
cannot
be closed
until
the
blown
fuse
is
acknowledged
by resetting
the
OFLO
.
The
fuse
,
of
course
,
must
be
replaced
.
The
OFLO
is
a
special
trip
device
having
three
(
3
)
shunt
trip
elements
(
one
per
phase
)
,
the coil
of
each
being
connected
MAINTENANCE
INSPECTION
3
.
Visually
check
the
breaker
for
loose hardware
on
the
breaker and the bottom
of
the
compartment
for
any
hardware
that has
fallen from
the breaker
.
4
.
Remove
the
arc
quenchers
and
inspect
the
arc
quenchers
and
contacts
for
breakage
or
excessive
burning
.
5
.
The
performance
of
the
solid
-
state
current
trip
devices
may
be
checked
with
a
suitable
test set
.
Check
electrome
-
chanical
devices
for
positive
trip
in
accordance
with
the
instructions
in
their Maintenance Manual
.
(
GEK
-
64459
)
6
.
Check
insulating
parts
for
evidence
of
overheating
and
for
cracks that
indicate excessive thermal
aging
.
Periodic
inspection
of
the circuit
breaker is recommended
at
least
once a
year
.
More
frequent
inspections
are
recom
-
mended
where
severe
load conditions
,
dust
,
moisture
or
other
unfavorable
conditions exist
,
or
if
the
vital
nature
of
the
load
warrants
it
.
Always
inspect
the breaker
after
a
short
-
circuit
current
has
been
interrupted
.
At
the time
of
inspection
,
the
following
checks
should
be
made
after
the breaker has been
deenergized
:
1
.
Manually
operate
the breaker several
times
,
checking
for
obstructions
or
excessive
friction
.
Manual
closing
of
an
electri
-
cally
operated
breaker
may
be
performed
by
the
following
two
steps
:
(
1
)
Install maintenance
crank
(
568
B
386
G
1
)
to
the
motor
gear
reducer
shaft
on
the
front
right
side
of
the
breaker
.
Ratchet
the
maintenance crank
up
and
down
until
the
springs
are
fully
charged
as
indicated
by
the distinct click
as
the
prop
is
set
and
prevents
any
further
charging
of
the
closing
springs
.
After
the
prop
is
set
do
not
apply
undue
force
to
the
maintenance handle
.
(
2
)
Manually
pull
the
armature
of
the
closing
solenoid
(
located behind the lower
right
-
hand
corner
of
the
escutcheon
)
toward the
front of
the breaker
.
This
dislodges
the
prop
and
allows the
closing springs
to
discharge
,
closing
the breaker
.
2
.
Electrically
operate
the breaker
several
times
to
check
performance
of
the
electrical accessories
.
LUBRSCATSGN
In
general
,
the circuit
breaker
requires
moderate lubrication
.
Bearing
points
and
sliding
surfaces
should be
lubricated
at
the
regular
inspection periods
with
a
thin
film
of GE
Lubricant
D
50
HD
38
(
Mobil
28
)
.
Before
lubricating
,
remove
any
hardened
grease
and dirt
from
latch
and
bearing
surfaces
with
kerosene
.
ALL
EXCESS
LUBRICANT
SHOULD
BE
REMOVED
WITH
A
CLEAN
CLOTH TO
AVOID
ACCUMULATION
OF
DIRT
OR
DUST
.
On
drawout breakers the
