INTRODUCTION
The
SE
-
100
S
switch
has
a
manually
charged
,
spring
stored
energy
operating
mechanism
capable
of
closing
the
switch
against
maximum
rated
short
circuited
current
.
Rotation
of
the
operating
handle
through
an
arc
of
180
degrees
provides
a
positive
action
closing
and
opening
operation
by
means
of
the
stored
energy
springs
.
The
type
SE
-
100
load
break
switch
is
a
manually
or
elec
-
trically
operated
,
triple
pole
disconnecting
switch
with
an
inte
-
gral
interrupter
that
has
capability
of
interrupting
transformer
magnetizing
and
load
currents
within
its
rating
.
The
switch
is
normally
furnished
with
outside
and
inter
-
phase
insulating
barriers
in
a
metal
-
enclosed
housing
.
It
can
be
connected
either
directly
to
the
incoming
side
of
a
power
transformer
,
the
primary
bus
,
or
to
cables
by
the
use
of
pot
-
heads
.
When
applied
with
power
fuses
,
the
combination
serves
as
a
successful
switching
and
fault
protection
device
.
The
SE
-
100
E
switch
is
similar
to
the
SE
-
100
S
except
that
it
has
an
electrically
charged
,
spring
stored
energy
operating
mechanism
having
the
same
closing
capabilities
.
The
switch
is
normally
operated
by
energizing
the
integral
electric
motor
that
charges
the
springs
for
positive
closing
and
opening
opera
-
tions
.
The
switch
can
be
quickly
converted
from
electrical
to
manual
operation
,
permitting
operations
with
an
operating
handle
for
maintenance
or
emergency
use
.
On
normal
feeder
or
single
circuit
applications
the
sta
-
tionary
contacts
of
the
load
break
switch
should
be
connected
to
the
source
of
power
and
the
moving
contact
blades
de
-
energized
when
the
switch
is
in
the
open
position
.
When
the
switch
is
used
in
more
complex
circuit
configurations
,
such
as
“
main
-
tie
-
main
”
or
“
double
feed
”
circuits
,
a
back
feed
can
ccur
which
results
in
the
moving
contact
blades
being
ener
-
gized
during
the
opening
operation
.
For
these
conditions
on
the
13.8
kV
switch
a
special
barrier
is
required
to
prevent
flashover
between
the
switch
blades
and
the
metal
front
of
the
enclosure
.
Special
barriers
are
not
required
on
the
4.8
kV
load
interrupter
switch
.
*
The
SE
-
100
M
switch
is
a
manually
closed
and
opened
switch
with
only
load
break
capability
as
indicated
on
the
nameplate
.
The
operating
handle
must
be
rotated
180
degrees
with
a
full
positive
motion
to
assure
proper
closing
and
open
-
ing
with
the
direct
drive
mechanism
.
The
operating
handle
is
often
interlocked
with
other
devices
such
as
secondary
circuit
breakers
in
order
to
assure
sequential
operation
.

RATINGS
the
use
of
an
arc
chute
type
interrupter
working
in
conjunc

tion
with
an
auxiliary
blade
.
As
the
switch
is
opened
the
auxiliary
blade
contacts
are
the
last
to
separate
and
will
ini
-
tiate
an
arc
within
the
interrupter
.
The
hot
arc
causes
gases
to
be
released
from
the
plastic
arc
chute
sides
in
such
volume
that
the
arc
is
blown
away
from
the
rapidly
moving
auxiliary
blade
and
is
cooled
by
contact
with
the
large
area
of
arc
chute
sides
.
After
the
arc
has
been
extinguished
,
the
blades
continue
to
open
,
providing
a
sufficient
air
gap
to
isolate
the
terminals
.

RECEIVING
AND
HANDLING
the
following
precautions
should
be
taken
to
insure
proper
storage
conditions
:
Immediately
upon
receipt
of
the
switch
,
an
examination
should
be
made
for
loss
or
damage
sustained
in
transit
.
If
in
-
jury
or
rough
handling
is
evident
,
a
damage
claim
should
be
filed
immediately
with
the
transportation
company
and
the

General
Electric
Apparatus
Sales
Office
should
be
noti

.
The
switch
should
be
stored
in
a
warm
dry
location
to
protect
the
insulation
parts
from
condensation
.
2
.
The
switch
should
be
stored
in
a
clean
location
free
from
corrosive
gases
or
fumes
.
Particular
care
should
be
taken
to
protect
the
equipment
from
moisture
and
cement
dust
,
as
this
combination
has
a
very
corrosive
effect
on
many
parts
.
Although
damage
due
to
handling
is
minimized
because
of
the
metal
enclosure
,
it
is
expected
that
due
care
will
be
exer
-
cised
in
the
unpacking
and
installation
of
the
switch
unit
so
that
no
damage
will
occur
from
careless
or
rough
handling
,
or
from
exposure
to
moisture
or
dirt
.
Care
should
be
exercised

prevent
tools
from
striking
any
part
of
the
housing

.
Machined
parts
of
the
operating
mechanism
should
be
coated
with
a
heavy
oil
or
grease
to
prevent
rusting
.
Loose
parts
associated
with
the
switch
are
always
included
in
the
same
crate
.
Check
all
parts
against
the
packing
list
to
be
sure
that
no
parts
have
been
overlooked
.
If
the
switch
is
stored
for
long
periods
of
time
,
periodic
in

spections
should
be
made
to
insure
that
corrosion
of
metallic
parts
or
deterioration
of
insulation
parts
has
not

whenever
it
becomes
necessary
to
