The
clearance
between
the
cup
(
3.3
)
and
the
nut
(
3.4
)
in
the
ON
switching
position
allows
the
magnetic
drive
to
accelerate
during
opening
operations
.
A
compression
spring
(
4.7
)
is
positioned
between
the
drive
lever
(
3.1
)
and
the
vacuum
interrupter
(
4.1
)
.
Description
of
Operation
(
Refer
to
Figure
1
.
)
The
drive
lever
(
3.1
)
forms
an
angle
,
with
point
A
as
the
fulcrum
.
When
the
magnet
is
not
energized
,
the
lever
is
held
in
the
OFF
position
by
the
compression
springs
(
9.3
)
.
Thus
point
B
of
the
drive
lever
is
in
its
extreme
left
position
.
At
this
point
the
drive
lever
engages
with
the
cup
(
3.3
)
and
the
nut
(
3.4
)
of
the
vacuum
interrupter
.
This
holds
the
contacts
apart
(
in
the
OFF
position
)
against
the
atmospheric
pressure
.
When
the
magnet
coil
(
8.1
)
is
energized
,
the
armature
(
3.6
)
and
with
it
the
drive
lever
(
3.1
)
are
attracted
towards
the
magnet
core
(
8.2
)
against
the
reaction
of
the
two
compression
springs
(
9.3
)
.
Point
B
of
the
drive
lever
therefore
moves
to
the
far
right
position
.
The
nut
(
3.4
)
of
the
vacuum
interrupter
(
4.1
)
is
thus
released
so
that
the
atmospheric
pressure
can
press
the
moving
contact
against
the
fixed
contact
.
The
drive
mechanism
is
constructed
so
that
the
nut
(
3.4
)
never
comes
into
contact
with
the
drive
lever
(
3.1
)
when
in
the
ON
position
.
This
ensures
that
the
ON
switching
position
is
always
reached
,
definitely
and
completely
.
Blown
Fuse
Trip
Mechanism
Contactors
can
be
supplied
with
an
anti
-
single
phase
trip
mechanism
which
offers
protection
from
single
phasing
due
to
a
blown
power
fuse
.
Fused
contactors
equipped
with
the
blown
fuse
trip
mechanism
are
pre
-
adjusted
at
the
factory
so
that
the
opening
of
one
or
more
power
fuses
results
in
de
-
energizing
the
contactor
,
thus
interrupting
current
to
the
load
.
When
a
power
fuse
blows
,
a
plunger
extends
from
the
load
end
of
the
fuse
which
rotates
the
spring
-
loaded
trip
bar
and
releases
a
pre
-
compressed
micro
-
switch
on
the
side
of
the
contactor
.
A
contact
on
the
micro
-
switch
opens
at
this
time
and
de
-
energizes
the
contactor
magnet
coil
.

AWARNING
Electrical
Connections
Inspect
all
insulated
wiring
to
see
that
no
damage
has
resulted
from
installing
the
contactor
.
Test
the
high
voltage
wiring
for
possible
grounds
or
short
circuits
.
A
dielectric
test
at
2.25
times
the
nominal
system
voltage
plus
2000
volts
applied
for
one
minute
between
phases
and
from
ail
phases
to
ground
is
the
preferred
method
.
Be
sure
to
disconnect
any
devices
(
control
power
transformer
,
etc
.
)
from
the
circuit
which
could
be
damaged
by
the
test
voltage
.
If
a
hi
-
pot
tester
is
not
available
,
then
a
Megger
test
at
1000
volts
is
a
suitable
second
choice
.
Accidental
contact
with
energized
wiring
or
bus
system
can
cause
electric
shock
,
burn
or
electrocution
.
Disconnect
and
lock
-
out
incoming
power
and
control
voltage
sources
before
begin
-
ning
work
on
this
or
any
other
electrical
equipment
.
h
Check
all
control
circuit
terminals
with
a
voltmeter
to
make
certain
that
the
equip
-
ment
is
totally
deenergized
.
Use
only
ap
-
proved
high

test
equipment
to
check
voltage
on
power
terminals
.
Do
not
attempt
to
measure
high
voltage
with
a
volt
-
ohm
meter
.
AWARNING
Excessive
dielectric
test
voltages
can
cause
harmful
x
-
radiation
to

bottles
.
It
is
recommended
that
a
safety
ground
be
connected
to
the
power
bus
after
the
sys
-
tem
has
been
deenergized
,
and
prior
to

Vacuum
contactors
are
sensitive
,
to
a
certain
degree
,
to
the
altitude
at
the
installation
site
.
This
is
due
to
the
fact
that
atmospheric
pressure
assists
in
closing
the
main
contacts
by
exerting
force
on
the
bellows
at
the
moveable
end
of
the
vacuum
bottles
.
Since
this
force
is
proportional
to
the
dif
-
ference
between
internal
bottle
pressure
and
external
atmos
-
pheric
pressure
,
the
contactor
’
s

must
be
adjusted
slightly

with
drawout
provisions
are
equipped
with
two
glass
polyester
interphase
barriers
and
one
horizontal
barrier
located
above
the
vacuum

which
acts
as
a
dust
cover
to
prevent
dust
and
other
foreign
material
from
accumulating
inside

tenance
on
the
vacuum
contactor
.
First
remove
the
inter
-
phase
barriers
,
by
sliding
upward
and
out
.
A
tab
located
on
the
rear
of
each
interphase
barrier
engages
a
notch
in
the
dust
cover
and
locks
it
into
the
assembly
.
Once
the
inter
-
phase
barriers
are
removed
,
the
dust
cover
will
slide
out
toward
the
rear
(
disconnect

)
end
of
the
contactor
.
Before
placing
the
contactor
back
in
service
,
both
interphase
barriers
and
the
dust
cover
must
be
replaced
in
their
proper
locations
.
Safety
For
the

to
hazards
associated
with
maintenance
activities
,
the
safety
related
to
work
practices
of
NFPA
70
E
,
part

.
Maintenance
personnel
should
be
trained
in
the
safety
practices
,
procedures
and
requirements
that
pertain
to
their
respective
job
assignments
.
The
customer
must
establish
a

Since
loss
of
vacuum
is
accompanied
by
loss
of
dielectric
strength
,
bottles
may
be
tested
for
sufficient
vacuum
level
by
performing
a
high
potential
dielectric
test
across
the
contacts
with
the
contactor
in
the
open
position
.
Main
Contacts
Wear
Check
The
recommended
method
of
determining
main
contact
wear
is
to
keep
records
as
accurately
as
possible
of
the
number
of
daily
switching cycles
along
with
the
amount
of
current
being
interrupted
.
By using
this
data
and the
graph
of
electrical
life
,
Figure
13
,
it
can
be
determined
with
sufficient
accuracy
when
the
contacts
in
the
vacuum
bottles
have reached
the end
of
their
service
life
.
At
this
point
,
the
vacuum
bottles
should
be
replaced
by
following
the instructions under
"
Vacuum Bottle
Replacement
.
"
It
should
be noted that
probability
of
replacing
a vacuum
bottle due
to
contact
wear
is
very
low
,
due
to
the
exceptionally
long
mechanical
and electrical
switching
life of
the
Siemens
VS
-
6602
vacuum
bottle
.
AWARNING
Excessive
dielectric
test
voltages
can
cause
harmful
x
-
radiation
to
be
emitted
from
vacuum
bottles
.
Do
not
exceed
13
,
250
volts
RMS AC
or
19
kV
DC
when
performing
dielectric
tests
.
AWARNING
Accidental
contact
with dielectric
test
equipment
can cause
shock
,
burn
or
electrocution
.
Dielectric
testing
should
only
be
con
-
ducted
by
qualified
personnel
.
Refer
to
test
device
instructions
for
safety
instruc
-
tions
.
With
the
vacuum
contactor
withdrawn
from
the controller
and
in
the
open
position
,
apply
13.25
kV
RMS
AC
across
the
open
contacts
of
each
bottle
for
one
minute
.
No breakdown
should
occur
.
If
breakdown
occurs
on
any
vacuum
bottle
,
it
must
be
replaced
.
If
a
DC
hi
-
pot
tester
is used
,
a
test
voltage
of
19
kV
DC
should
be
applied
.

Electrical
Life
Curve
Vacuum
Loss
Check
It
is
highly
unlikely
that
a
vacuum
bottle
will
ever
suffer
loss
of
vacuum
.
The
vacuum
bottle
has been
designed
and tested
to
maintain
the
level
of
internal
pressure
necessary
to
proper
operation
for
at
least
20
years
of
shelf
life
.
Since
switching
under
load
tends
to
increase
the level
of
vacuum
,
due
to
a
phenomenon
known
as
“
gettering
”
,
the
life
of
bottles which
have
been
placed
in
operation
will
be extended
even
further
.
