Circuit
Breaker
Operation
With
the mechanism
latched and the
contacts
open
,
the
oper
-
ating
handle
will
be
in
the
OFF
position
.
Moving
the
handle
to
the
ON
position
closes the
contacts
and establishes
a
circuit
through
the
breaker
.
Under
overload
or
short circuit conditions
sufficient
to
automatically
trip
or
open
the breaker
,
the
oper
-
ating
handle
moves
to
a
position
between
ON
and
OFF
To
relatch the circuit breaker
after
automatic
operation
,
move
the
operating
handle
to
the
extreme
OFF
position
.
The circuit
breaker is
now
ready
for
reclosing
.
The
overcenter
toggle
mechanism
is
trip
free
of
the
operat
-
ing
handle
.
The circuit breaker
,
therefore
,
cannot
be held
closed
by
means
of
the handle
should
a
tripping
condition
exist
.
After
automatic
operation
,
the handle
assumes an
inter
-
mediate
position
between
ON
and
OFF
,
displaying
a
clear
indication
of
tripping
.
Molded
Case
Switch
A
molded
case
switch
is
available
in
the
MXD
6
,
CMD
6
,
NXD
6
and
CND
6
type
circuit breakers
.
This device
employs
the
same
operating
mechanism
as
the thermal
magnetic
and
magnetic only
units
.
A
preset
instantaneous
function
has been
factory
installed
to
allow the switch
to
trip
and
protect
itself
against
high
fault
conditions
.
No overload
or
low
fault
protec
-
tion is
provided
.
This
protection
must
be
supplied
by
separate
overcurrent
devices
.
