This
electrically
operated
breaker
closes
whenever
the
closing
solenoid
coil
is
energized
.
This
causes
an
upward
movement
of
the
solenoid
armature
which
charges
the
springs
to
a
predetermined
over

point
for

This
electrically
operated
breaker
utilizes
a
motor
to
auto
-
matically
keep
the
closing
springs
in
a
charged
state
.
Whenever
the
control
solenoid
is
energized
,
its
operation
releases
the
closing
springs
,
closing
the
breaker
contacts
.

The
initiation
of
the
closing
operation
for
both
of
the
above
types
of
breakers
is
by
closing
of
a
contact
of
a
remote
switch
,
relay
or
a
close
button
in
the
front
escutcheon
if
the
breaker
is
so
equipped
.
The
breakers
control
schemes
have
an
anti
-
pump
feature
which
allows
only
one
closure
of
the
breaker
for
a
single
operation
of
the
closing
contact
no
matter
how
long
the
contact
may
be
held
closed
.
This
prevents
the
repeated
operations
that
would
ensue
if
one
of
the
automatic
trip
devices
was
activated
at
the
time
of
closing
.
A
manual
closing
handle
is
provided
for
maintenance
purposes
.
All
electrically
operated
breakers
close
within
five
cycles
.
