INTRODUCTION
The
magne
-
blast
circuit
breaker
is
the
removable
interrupting
element
for
|
|
use
in
vertical
-
lift
metal
-
clad
switchgear
,
to
provide
reliable
control
‘
"
and
protection
of
power
systems
.
Among
the
many
advantages
of
metal
-
clad
switchgear
are
added
protection
to
equipment
and
personnel
,
compactness
,
simplified
installation
and
reduced
maintenance
.
In
keeping
with
these
features
the
magne
-
blast
breakers
are
designed
for
interchangeability
and
maneuverability
,
together
with
reliability
and
low
maintenance
require
-
ments
.
The
magne
-
blast
circuit
breaker
operates
on
the
principle
that
an
arc
can
be
interrupted
in
air
by
sufficiently
elongating
and
cooling
it
.
This
is
accomplished
by
means
of
a
strong
magnetic
field
that
lengthens
the
arc
and
forces
it
into
intimate
contact
with
cool
dielectric
material
.
A
sturdy
,
reliable
operating
mechanism
assures
low
maintenance
and
long
life
.
The
AM
-
13.8
magne
-
blast
breaker
is
available
in
a
number
of
current
ratings
.
Refer
to
the
breaker
nameplate
for
the
complete
rating
information
of
any
particular
breaker
.
The
short
circuit
conditions
to
be
imposed
on
the
breaker
must
not
exceed
its
rating
,
nor
should
it
be
called
upon
to
operate
at
voltages
or
currents
greater
than
those
given
on
the
nameplate
.
Since
this
book
is
written
to
cover
several
ratings
of
breakers
that
are
of
the
same
general
design
,
all
instructions
will
be
of
a
general
character
and
all
illustrations
will
be
typical
,
unless
otherwise
specified
.
Sv
,
PROPER
INSTALLATION
AND
MAINTENANCE
ARE
NECESSARY
TO
INSURE
CONTINUED
SATISFACTORY
OPERATION
OF
THE
BREAKER
,
The
following
instructions
will
provide
complete
information
for
placing
magne
-
blast
breakers
in
service
and
for
maintaining
satisfactory
operation
.
These
Instructions
do
not
purport
to
cover
all
details
or
variations
in
equipment
nor
to
provide
for
every
possible
contingency
to

in
connection
with
installation
,
operation
or
maintenance
,
information
be
desired
or
should
particular
problems
arise
which
are
not
covered
sufficiently
for
the
purchaser
