INTRODUCTION
These
instructions
contain
the
information
required
to
properly
install
,
operate
,
and
test
the
complete
line
of
Type
51
solid
-
state
overcurrent
relays
.
The
CIRCUIT
-
SHIELD
overcurrent
relay
is
housed
in
a
semi
-
flush
drawout
relay
suitable
for
conventional
panel
mounting
.
All
connections
to
the
relay
are
made
at
terminals
located
on
the
rear
of
the
case
and
clearly
numbered
,
one
(
1
)
through
twelve
(
12
)
.
CURRENT
,
TIME
,
and
INST
,
pickup
controls
are
lo
-
cated
on
the
front
panel
behind
a
removable
clear
plastic
cover
.
TIME
and
INST
,
target
indicators
are
also
mounted
on
the
front
panel
.
Both
targets
are
reset
by
means
of
a
pushbutton
extending
through
the
relay
cover
.
PRECAUTIONS
The
following
precautions
should
be
taken
when
applying
solid
-
state
relays
:
1
.
Incorrect
wiring
may
result
in
damage
to
solid
-
state
relays
,
Be
sure
wiring
agrees
with
the
connection
diagram
for
the
particular
relay
before
the
relay
is
energized
.
Be
sure
control
power
is
applied
in
the
correct
polarity
before
applying
control
power
.
2
.
Apply
only
the
rated
control
voltage
marked
on
the
relay
front
panel
.
Unlike
conventional
relay
contacts
,
solid
-
state
outputs
are
rated
for
a
particular
control
voltage
.
If
rectified
AC
voltage
is
used
in
place
of
a
battery
,
proper
filtering
will
be
required
to
insure

RECEIVING
,
HANDLING
,
STORAGE
Upon
receipt
of
the
CIRCUIT
-
SHIELD
relay
(
when
not
included
as
part
of
a
switchboard
)
examine
for
shipping
damage
.
If
damage
or
loss
is
evident
,
file
a
claim
at
once
and
promptly
notify
the
nearest
Asea
Brown
Boveri
Of
-
fice
.
Use
normal
care
in
handling
to
avoid
mechanical
damage
.
The
CIRCUIT
-
SHIELD
system
has
no
vital
moving
parts
and
if
kept
reasonably
clean
and
dry
,
has
no
practical
limit
to
its
operating
life
.

INSTALLATION
Mounting
The
outline

and
panel
drilling
and
cutout
information
is
given
in
Figure
2
.
Connections
External
connection
diagram
is
shown
in
Figure
1
.
For
the
instantaneous
function
to
be
operable
Terminals
9
and
10
must
be
externally
shorted
.
Instantaneous
relay
operation
can
be
cancelled
for
reclosing
applications
by
using
an
external
supervisory
contact
connected
to
these
terminals
.
For
example
,
if
the
phase
one
(
1
)
tap
is
set
at
six
(
6
)
amperes
and
the
INST
dial
is
set
at
eight
(
8
)
,
the
INST
,
setting
is
:
For
the
TIME
function
to
be
operable
terminals
10
and
11
must
be
externally
shorted
.
The
TIME
function
can
be
cancelled
for
directional
or
voltage
control
by
using
an
external
supervisory
contact
connected
to
these
terminals
.
6
amps
X
8
=
48
amps
Consequently
,
an
instantaneous
trip
will
occur
at
48
amps
in
phase
one
(
1
)
of
the
relay
.
TESTING
IN
SERVICE
In
general
,
it
is
not
necessary
to
schedule
periodic
maintenance
of
this
relay
.
However
,
if
a
trip
test
is
desired
to
confirm
the
proper
functioning
of
the
system
,
the
following
procedure
can
be
used
.
Mounted
in
Switchgear
Tests
should
be
made
on
a
de
-
energized
main
circuit
.
If
tests
are
to
be
made
on
an
energized
circuit
,
be
sure
to
take
all
necessary
precautions
.
It
is
customary
to
test
the
trip
circuit
of
electro
-
mechanical
overcurrent
relays
by
manually
closing
the
trip
contacts
to
trip
their
associated
circuit
breakers
.
If
the
contacts
are
allowed
to
part
before
the
seal
-
in
contact
closes
,
the
relay
contacts
are
eroded
by
the
arc
.
Also
,
high
transient
voltages
will
appear
from
trip
bus
to
positive
.
This
problem
is
avoided
in
the
CIRCUIT
-
SHIELD
overcurrent
relay
by
the
operatic
nal
test
feature
.
Separate
pushbuttons
labeled
"
TRIP
'
'
are
provided
for
the
TIME
and
INST
,
functions
.
The
pushbuttons
,
recessed
to
prevent
accidental
operations
,
will
cause
the
breaker
to
trip
.
All
CIRCUIT
-
SHIELD
relays
have
metal
front
panels
which
are
connected
through
printed
circuit
board
runs
and
connector
wiring
to
a
terminal
at
the
rear
of
the
relay
case
.
The
terminal
is
marked
"
G
"
and
is
located
as
shown
in
Fig
.
2
below
.
In
all
applications
this
terminal
should
be
wired
to
ground
.
Special
care
must
be
taken
to
connect
control
power
in
the
proper
polarity
.
Reversing
plus
(
+
)
and
minus
(
-
)
will
cause
SCR
A
and
SCR
Bto
block
the
flow
of
trip
current
and
the
relay
will
not
function
.
For
capacitor
trip
applications
,
the
plus
{
+
)
output
of
the
capacitor
trip
device
must
be
connected
to
terminal
7
of
the
relay
,
the
negative
(
-
)
to
terminal
8
.

.
SETTINGS
Current
Pickup
Taps
A
tap
block
for
each
phase
is
located
on
the
relay
front
panel
.
Each
tap
block
provides
for
seven
(
7
)
pickup
settings
which
are
marked
in
CT
secondary
amperes
.
When
a
pin
is
pulled
out
.
that
phase
switches
to
the
maximum
tap
setting
.
The
pin
may
be
moved
with

STATE
OVERCURRENT
RELAYS
OUTPUT
CIRCUIT
The
CIRCUIT
-
SHIELD
overcurrent
relay
energizes
the
breaker
trip
coil
by
means
of
an
output
SCR
.
Two
SCR
’
s
are
provided
,
one
for
the
time
delay
and
pne
for
the
instantaneous
circuit
as
indicated
in
the
wiring
diagram
shown
in
Figure
1
.
As
shown
,
relay
terminal
7
is
connected
to
the
control
power
positive
,
with
the
trip
coil
connected
to
relay
terminal
12
through
a
52
/
a
contact
.
SCR
A
is
gated
by
the
time
delay
circuit
,
while
SCR
B
is
gated
by
the
instantaneous
circuit
.
Note
that
once
an
SCR
is
gated
(
turned
on
)
,
it
will
remain
in
conduction
until
its
anode
current
falls
below
its
holding
current
which
typically
is
5
to
20
milliamperes
.
Consequently
,
the
trip

BURDEN
The
burden
of
the
Circuit
Shield
overcurrent
relay
is
very
low
,
allowing
the
use
of
current
transformers
which
would
give
unsatisfactory
performance
if
they
were
driving
electro
-
mechanical
relays
.
Because
the
input
characteristic
of
the
Circuit
Shield
relay
is
nonlinear
,
an
impedance
cannot
be
specified
,

,
the

TARGET
CIRCUITS
The
target
indicators
for
the
TIME
and
INST
,
circuits
are
polarity
sensitive
devices
which
are
set
by
current
flow
through
the
corresponding
trip
SCR
.
Target
reset
is
accomplished
by
the
control
power
connection
(
terminals
7
and
8
of
Figure
1
)
through
the
TARGET
RESET
pushbutton
.
Standard
relays
have
2
targets
TIME
and
INST
.
Three
phase
relays
may
be
specially
ordered
with
5
targets
—
TIME
,
INST
,
and
PHASE
targets
.
These
3
additional
targets
wil
indicate
which
phase
currents
are
in
excess
of
tap
setting
when
the
relay
trips
the
breaker
