GE AKR-30S Installation And Maintenance Instructions

Operation
SECTION

would
ensue
if
one
of
the
automatic
trip
devices
were
activated
at
the
time
of
closing
.
The
“
E
”
relay
,
together
with
the
cutoff
switch
,
provides
the
anti
-
pump
feature
.
The
mechanical
action
of
closing
operates
the
cutoff
switch
,
reversing
the
position
of
the
contacts
from
that
shown
on
the
diagram
.
This
energizes
the
“
E
”
relay
,
if
contact
is
still
maintained
at
the
closing
switch
,
with
the
result
that
the
“
K
”
relay
circuit
is
opened
by
“
E
”
contacts
5
-
6
.
This
prevents
the
“
K
”
relay
from
again
becoming
energized
.
“
E
”
contact
1
-
2
seals
in
the
“
E
”
coil
as
long
as
contact
is
maintained
at
the
closing
switch
.
Electrically
operated
breakers
may
also
be
closed
by
means
of
the
maintenance
handle
which
is
furnished
with
the
breaker
.
This
is
a
separate
tool
and
is
simply
a
lever
which
permits
an
operator
to
push
upwards
on
the
closing
solenoid
armature
.
Two
small
hooks
on
one
end
of
maintenance
handle
are
engaged
in
slots
(
12
)
,
Fig
.

,
located
in
the
lower
portion
of
the
front
escutcheon
(
10
)
.
Rotation
of
the
long
end
of
the
handle
downwards
forces
the
shorter
end
of
the
handle
upwards
against
the
bottom
of
the
solenoid
armature
,
and
closes
the
breaker
.
Electrical
Operation
(
See
Fig
.
1
)
The
electrically
operated
breaker
closes
whenever
the
closing
solenoid
coil
is
energized
.
This
causes
an
upward
movement
of
the
solenoid
armature
,
which
initiates
the
mechanical
closing
action
.
The
closing
signal
may
be
given
either
by
a
remote
switch
or
relay
,
or
by
a
closing
button
in
the
front
escutcheon
if
the
breaker
is
so
equipped
.
Either
action
(
refer
to
the
elementary
of
the
wiring
diagram
)
energizes
the
coil
of
the
“
K
”
relay
through
the
normally
closed
contacts
of
cutoff
switch
G
and
the
normally
closed
contacts
of
the
“
E
”
relay
.
When
the
“
K
”
relay
or
contactor
is
energized
,
it
closes
its
contacts
.
One
of
these
(
“
K
”
1
-
2
)
seals
in
the
“
K
”
coil
.
The
other
three
sets
of
contacts
,
which
are
arranged
in
series
,
activate
the
closing
solenoid
.
The
breaker
control
scheme
has
an
anti
-
pump
feature
which
allows
only
one
closure
of
the
breaker
for
a
single
operation
of
the
closing
switch
no
matter
how
long
the
switch
may
be
held
closed
.
This
prevents
the
repeated
operations
