Introduction
Receiving
:
Circuit
breakers
are
normally
shipped
from
the
factory
com
-
pletely
assembled
,
inspected
,
tested
and
packed
.
Immedi
-
ately
upon
receipt
of
a
breaker
check
each
item
with
the
shipping
manifest
and
make
an
examination
for
evidence
of
any
dam
-
age
that
may
have
occurred
during
shipment
,
removing
pack
-
aging
carefully
with
correct
tools
where
necessary
.
If
any
shortage
,
damage
or
indication
of
rough
handling
is
found
,
immediately
call
it
to
the
attention
of
the
local
freight
agent
handling
the
shipment
.
Proper
notation
should
be
made
by
him
on
the

is
made
and
facilitates
adjustment
.
Also
,
immediately
file
a
damage
claim
with
the
transportation
company
and
notify
the
nearest
Siemens
sales
representative
.
The
MSV
and
FSV
series
of
vacuum
circuit
breakers
are
pre
-
cision
built
devices
designed
to
function
efficiently
under
nor
-
mal
operating
conditions
.
They
are
designed
and
manufactured
to
operate
within
the
ANSI
C
37
standards
for
“
Indoor
"
oiless
circuit
breakers
.
Performance
requirements
of
these
stan

dards
are
met
or
exceeded
by

The
successful
performance
and
application
of
these
vacuum
breakers
depends
as
much
on
proper
installation
and
main
-
tenance
as
it
does
on
good
design
and
careful
manufacture
.
The

maintenance
and
operation
and
are
provided
to
aid
you
in
obtaining
longer
and
economical
service
from
your
Siemens
circuit

tion
—
resulting
in
better
service
and
lower
maintenance
costs
—
this
information
should
be

Storage
NOTE
:
The
circuit
breaker
should be installed
as soon as
possible
.
If
storage
is
necessary
,
‘
As
Found
'
tests
are
recommended
prior
to
and
after
storage
for
comparison
.
For
storage
,
the
circuit
breakers should be
kept
indoors
in
a
clean
dry
protected
location
where
they
will
not
be
exposed
to
such
items
as
dirt
,
construction dust
,
corrosive
atmospheres
,
mechanical
abuse
or
rapid
temperature
variation
.
Outdoor
storage
of
circuit
breakers
is
not
recommended
.
If
breakers
must
be stored
outdoors
,
they
must
be
completely
covered
and
protected
from
the
elements
.
A
heat
source
must
be
provided
to
prevent
condensation
and
subsequent
corro
-
sion
.
Covering
should
allow
for
ventilation
.
Often
500
watts
heat
per
breaker
is
used
.
It
is
recommended
that
periodic inspection
of
the breakers
be
made
during
storage
and
if
necessary
procedures
adjusted
to
keep
the breakers
in
proper
condition
.

With
the breaker
open
,
check
each

across
the

by connecting
from

A
dielectric

should
be
made
at

The

provides
a

of
ac
-
tivities
to
be
performed
while
preparing
the
circuit

for

and
prior
to

.
When
the

is

Doble

for

of

change
.
Contact
resistance
tests
can
also
be
made
using
a
ductor
.
This
is recommended
for
all
new
circuit breakers
especially
if
they
are
to
be
stored
for
extended
periods
,
as
they
may
absorb
moisture and
contaminants
.
This should
also
be
done
after
storage
and
prior
to
placing
breakers
into
service
.
Changes
in
values
between
subsequent
tests
should be
eval
-
uated and
corrective
action taken
where
needed
.
Since
wide
variations
can
occur
in
insulation values
and

because
of

.
However
,
making
and
recording
these
tests
on

,
and
again
at
regular
intervals
,
will
give
