OPTIONAL
DEVICES
OPERATION COUNTER
This
option
consists
of
a
mechanically
operated
counter
with
a
bracket
that
mounts
at
the
bottom
of
the
breaker
mounted
auxiliary
switch.
The
counter
arm
connects
through
a
spring
to
the
switch
operating
arm.
The
counter
is
non-resettable.
The
breaker
must
have an
auxiliary
switch
for
this
option
to
mount.
MAINTENANCE CLOSING
DEVICE
This device is a manual charging handle assembly ar-
ranged
for
use
as
a
maintenance
tool.
The
charge
link
is
spring
loaded and retained
to
make
insertion
into
the
breaker
frame less
difficult
and
the
pivot
pin
is retained
by
a
chain.
After
charging
the
closing
springs,
the
handle
must
be
manually
returned
to
the
vertical
position
to
allow
closing
the breaker.
ELECTRICALLY OPERATED
INTERLOCK
These devices
amount
to
an
additional
solenoid
that
must
be
energized
before
the
breaker
can
be closed. When
the
device
is
de-energized
the
breaker
is held
trip-free
so
that
it
cannot
be closed
either
electrically
or
manually.
The
devices
are available
for
48, 125
and
250
volt
D.C. as
well
as
for
120 and 240
volt
A.C.
They
are
similar
in
construc-
tion
and
mount
in the same
location
as
the
undervoltage
trip
device.
The
electrical
interlock
has a
mechanical
link
from
the
device
to
the
main
shaft
of
the
breaker
to
hold
the
device
in
the
picked-up
position
when
the
breaker
is
closed.
Once
closed
the
device
can
be
de-energized
with-
out
tripping
the breaker.
There
are
no
adjustments
for
pick-up
or
drop-out
voltages
of
the
device.
The
devices
are designed
to
be energized
continuously.
UNDERVOLTAGE TRIP
DEVICE OPTION
This
device
automatically
trips
the
circuit
breaker
on
loss
of
voltage.
Either
instantaneous
or
time-delay
operation
can
be
supplied.
A .06
inches
(1.5
mm)
gap
should
be
Page 19
maintained
between
flap
extension
and
pull
link
when
the
device
is
energized
with
the
pick-up
and
drop-out
is
set
so
that
the
device
picks
up
at
a
voltage
of
85%
or
less
and
drops
out
between
30
and 60%
of
rated value.
NOTE
Pick-up
and
drop-out
are
individually
adjust-
able.
Timedelayisadjustablefrom
.04to4sec.
LATCH
CHECK
SWITCH
This
option
is a
small
switch
mounted
on
a
bracket.
The
switch
operator
is
adjusted
so
the
switch
is operated
by
and
indicates
the
position
of
the
breaker
trip
flap.
The
latch
check
switch
may
be used in
conjunction
with
the
electrical
interlock
or
undervoltage
devices
to
delay
the
application
of
voltage
to
the
close
coil
until
the
undervolt-
age
or
interlock
device
has
picked-up.
STATIC TRIP
II
The
Static
Trip
II
device
mounts
onto
a
slide-type
bracket
on
the
circuit
breaker.
To
remove
trip
device,
the
terminal
block
cover
located
above it
should
be
removed,
exposing
the
terminal
block
screws.
The
lower
row
of
screws
can
be
loosened
with
a
screwdriver
allowing
the
terminal
block
fanning
strip
to
be removed
from
the
terminal
block.
Re-
moval
of
the
fanning
strip
exposes a
mounting
screw.
This
screw
can be
removed,
allowing
the
static
trip
device
to
be
removed
from
the
circuit
breaker.
Just
pull
the
trip
device
towards
the
front
of
the
circuit
breaker. See
Instruction
Book
SG-3098
for
operating
instructions.
BELL ALARM SWITCH
OPTION
This
unit
functions
to
operate
a
switch.
A
single-pole
double-throw,
or
a
double-pole
double-throw
switch
is
available.
The
switch
operator
is
connected
to
and
oper-
ated
by
the
tripping
actuator.
The
switch
operator
remains
tripped
even
when
the
actuator
is
reset
by
the
circuit
breaker.
The
switch
operator
must
be reset
either
manu-
ally
or
by
an
additional
optional
electrical
reset
solenoid.
The
contacts
of
the
bell alarm
switch
can
be
connected
in
series
with
the
circuit
breaker
closing
coil,
to
provide
a
lockout
feature
to
prevent
reclosing
after a
fault.
