INTRODUCTION

1.1
PRODUCT
DESCRIPTION
The
FB
600
E
is
a
static
.
trip
relay
used
to
cause
a
low
voltage
breaker
to
open
under
fault
conditions
.
Its
primary
application
is
as
a
retrofit
to
600
volt
breakers
for
upgrading
existing protection
.
By
using
special
CT
'
s
with
both
1
amp
signal windings
and
a
separate
power
winding
,
the
FB
600
E
relay
requires
no
control
power
to
operate
.
An
output
pulse
from
the
FB
600
E
relay
is
used
to
drive
an
actuator
which
causes
the
breaker
to
trip
.
The
FB
600
E
will
trip
on
overloads
with
separately
adjustable
,
instan
-
taneous
,
short
time
and
long
time
pickup
levels
.
The short
and
long
delay
times
are
also
adjustable
.
A
long
time
pickup
LED
is
provided
to
assist
in
verifying
the
pickup
threshold
.
To
help
determine
the
cause
of
trip
,
an
indicator
is
provided
for
instantaneous
,
or
short
time
,
trip
and
'
a
separate
indicator
is
used
for
long
time
trip
.
Also
included
with
the
FB
600
E
is
a
ground
fault
trip
and
a
latched
ground
fault
indicator
to
diagnose
the
cause
of
trip
.

To
allow
access
to

settings
,
a
hinged
cover
with
a
spring
release
catch
is
provided
.
This
allows
pickup

quickly
set

modified
without
the
need
of
tools
.
When
mounting
the

provision
should
be
made
for
the
cover
to
partially
open
to
allow
access
to
the

The
latched
trip
indicators
and
external
wiring
terminals
are
mounted
outside
the
hinged
cover
.
Orient
the
relay
on
the
breaker
to
allow
access
to
the
terminal
block
for
relay
testing
and
to
ensure
that
the

The

is
the

600
E
connected
to
detect
short
circuit
and
overloads
but
no
ground
faults
as
shown
in
figure
2.2
.
Each
of
the
specially
wound
phase
current
transformers
(
CT

)
has
a
signal
winding
and
a
.
power
winding
thus
eliminating
the
need
for
an
external
control
power
source
.
When
a
trip
condition
occurs
,
a
short
pulse
is
provided
to
the
spring
loaded
actuator
which
triggers
the
breaker
to
open
.
The
CT
signal
winding

However

Fault
Sensing
:
In
a
4
wire
system
where
it is
inconvenient
to
run
the
3
phases
and
neutral
through
a
separate
ground
fault
CT
the
wiring
scheme of
figure
2.5
can
be used
.
The
residual
current
in
the
return
wire
of
the
3
phase
CT
'
s
is
sensed
.
Under unbalanced
conditions
this
current
will
not
be
zero
even
with
no
ground
fault
since
the
residual
current
will
flow
in
the fourth neutral
wire
.
Consequently
,
a
separate
CT
of the
same
ratio
as
the
phase
CT
is
used
to
sense
the
neutral
current
and
is
connected
to
exactly
cancel the
.
phase
CT
residual
current
.
Now
if
a
ground
fault
occurs
,
the
residual
current
will
no
longer
be
cancelled
by
the
neutral
wire
current
and
the
FB
600
E
will
trip
when
the
appropriate
pickup
level
and
time
delay
is
obtained
.
The
CT
signal winding
common
(
terminals
)
may
be
externally
connected
to
ground
.
However
,
the
power
winding
common
terminal
(
1.0
)
and
actuator
terminals
(
11

)
must not
be
externally grounded

on

or
it
will
not

CURRENT
TRANSFORMERS
t
Any
current
transformer
having
both
a
signal
and
power
winding
can
be
used
with
the
FB
600
E
,
Primary
current
ratios
may
cover
any
range
typically
from
100
to
4000
amps
in
suitable
increments
or
CT
'
s
may
have
several
taps
.
A
few
notes
of
caution
are
in
order
regarding
the
CT
'
s
used
in
conjunction
with
the
FB
600
E
.
These
notes
are
:
The
signal
winding
must
have
an
output
of
1
amp
at
the
rated
primary
current
into
a
nominal
resistive
burden
of
0.5
ohms
.
The
power
winding
should
saturate
below
the
CT
rated
amps
and
provide
approximately
10
VA
max
.
The
zero
sequence
ground
fault
CT
is
similar
to
the
phase
CT
.
The
FB
600
E
power
inputs
will
increase
in
burden
with
increased
power
input
.
At
the
worst
case
,
the
FB
600
E
power
inputs
will
burden
the
power
windings
to
a
point
where
the
burden
voltage
is
100
volts
.
Figure
2.6
describes
the
loading
on
the
power
windings
of
the
CT
'
s
.
If
the
power
windings
of
the
CT
'
s
do
not
limit
(
or
saturate
)
their
power
outputs
as
described
in
(
b
)
,
damage
to
the
FB
600
E
may
.
result
.
Carriere
can
provide
specially
designed
CT
'
s
from
stock
which
will
limit
output
power
from
the
power

.
These
Carriere
CT
'
s
are
available
in
several
ratios
.
Please
contact
the
factory
or
a
Carriere
agent
for
more
information
.
In
order
to
ensure
proper
operation
of
all
FB
600
E
functions
,
the
power
windings
must
be
able
to
provide
(

at
least
4.5
