)

Effective

:
Introduction
Eaton
'
s
MRR
1000
provides
a
means
of
remotely
inserting
or
remov
-
ing
any
drawout
circuit
breaker
in
the
Magnum
DS
®
family
of
Power
Circuit
Breakers
(
PCBs
)
.
In
addition
,
the
MRR
1000
enables
the
operator
to
remotely
open
and
close
any
Magnum
DS
circuit
breaker
utilizing
the
pushbuttons
on
the
face
of
the
breaker
.
Increased
safety
precautions
and
the
need
to
protect
personnel
from
the
dan
-
gers
of
potential
arc
flash
occurrences
suggest
the
need
to
increase
the
distance
between
an
operator
and
the
front
of
a
switchgear
or
switchboard
during
racking
operations
.
With
the
MRR
1000
,
an
operator
can
be
up
to
25
feet
away
from
the
breaker
compartment
door
during
the
rack
-
in
or
rack
-
out
process
.
Electric
arcs
result
from
thermal
ionization
that
occurs
when
current
flow
is
interrupted
by
the
separation
of
conductors
.
Thermal
ioniza
-
tion
can
generate
temperatures
as
high
as
35
,
000
°
F
Conductor
materials
melt
into
metal
vapor
and
the
surrounding
air
is
ionized
.
If
the
arc
is
external
of
the
interrupting
chamber
of
a
power
circuit
breaker
,
then
a
violent
explosion
occurs
resulting
in
an
inferno
of
ionized
gases
,
molten
debris
,
metal
shrapnel
,
and
a
flash
of
light
(
arc
flash
)
.
When
arc
flash
initiates
within
a
switchgear
/
switchboard
cabi
-
net
,
the
rapidly
escalating
pressure
can
dislodge
compartment
doors
and
side
sheets
of
the
switchgear
and
turn
hardware
into
high
-
speed
projectiles
.
Arc
flash
levels
are
a
function
of
circuit
voltage
,
maximum
available
short
circuit
current
at
the
point
of
flashover
,
conditions
of
confine
-
ment
,
and
the
distance
between
the
point
of
flashover
and
the
point
of
measurement
.
Operating
personnel
are
typically
within
two
feet
of
the
front
of
the
power
circuit
breaker
during
the
racking
process
.
In
the
event
of
an
arc
flash
event
,
this
close
proximity
could
cause
serious
injury
or
death
.
NFPA
70
E
provides
guidance
for
the
requirements
of
person
-
al
protective
equipment
(
PPE
)
to
protect
personnel
from
the
dangers
of
arc
flash
exposure
.
PPE
for
high
levels
of
arc
flash
can
be
bulky
,
hot
and
uncomfortable
.
This
may
dissuade
personnel
from
wearing
proper
protection
.
The
best
way
to
limit
exposure
to
arc
flash
during
the
process
of
racking
Power
Circuit
Breakers
is
to
put
more
dis
-
tance
between
the
person
and
the
possible
point
of
exposure
.
Eaton
'
s
remote
racking
device
fulfills
the
objective
of
increased
worker
safety
by
permitting
routine
operations
from
an
increased
distance
from
the
power
circuit
breaker
.
1.1
Compatibility
The
remote
racking
device
is
compatible
with
any
drawout
breaker
in
the
Magnum
DS
family
of
Power
Circuit
Breakers
(
PCBs
)
.
This
includes
the
Magnum
DS
standard
frame
,
narrow
frame
and
double
-
wide
frame
rated
for
switchgear
(
ANSI
)
,
Magnum
SB
switchboard
class
and
IEC
60947
-
2
applications
;
as
well
as
CM
52
network
pro
-
tector
breakers
.
The
application
may
be
used
while
enclosed
in
Magnum
DS
Low
-
Voltage
Switchgear
and
Switchboards
with
the
breaker
compartment
door
closed
.
The
MRR
1000
is
also
compatible
with
Magnum
DS
ARC
Resistant
Switchgear
and
also
compatible
with
Magnum
DS
family
of
drawout
PCBs
in
other
OEM
installa
-
tions
.
A
CAUTION
THE
CASE
DIMENSIONS
,
RETENTION

MECHA
-
NISM
OF
THE
MRR
1000
ARE
DESIGNED
TO
WORK
EXCLUSIVELY
WITH
THE
MAGNUM
DS
FAMILY
OF
PCBS
.
ANY
ATTEMPT
TO
USE
THE
DEVICE
WITH
ANOTHER
MANUFACTURER
'
S
BREAKER
WILL
PUT
THE
OPERATOR
AT
RISK
OF
INJURY
AND
WILL
VOID
THE
WARRANTY
.
Unlike
some
remote
operating
devices
,
the
MRR
1000
requires
no
additional
mounting
kit
on
the
body
of
the
circuit
breaker
or
on
the
surface
of
the
switchgear
/
switchboard
.
In
fact
,
no
modification
or
additional
tools
are
required
.
The
MRR
1000
utilizes
features
found
on
every
breaker
of
the
Magnum
DS
family
,
making
it
convenient
to
install
and
use
.

Safe
Practices
for
Power
Circuit
Breakers
The
Magnum
DS
family
of
Power
Circuit
Breakers
are
equipped
with
high
speed
,
stored
energy
operating
mechanisms
.
They
are
designed
with
several
built
-
in
interlocks
and
safety
features
to
provide
safe
and
proper
operating
sequences
.
Section

:
Receiving
,
Handling
,
and
Storage
Magnum
Remote
Racking
Device
(
MRRtOOO
)
units
are
subjected
to
complete
factory
production
tests
and
inspection
before
being
packed
.
They
are
shipped
in
containers
designed
to
provide
maxi
-
mum
protection
to
the
equipment
during
shipment
and
storage
and
at
the
same
time
to
provide
convenient
handling
.
3.1
Receiving
Until
the
MRR
1000
unit
is
ready
to
be
delivered
to
the
point
of
use
,
do
not
remove
it
from
the
shipping
box
.
If
the
unit
is
to
be
placed
in
storage
for
an
extended
period
,
maximum
protection
can
be
obtained
by
keeping
it
in
its
box
.
Upon
receipt
of
the
equipment
,
inspect
the
box
for
any
signs
of
damage
or
rough
handling
.
Open
the
box
carefully
to
avoid
any
dam
-
age
to
the
contents
.
Use
care
when
using
a
box
cutter
or
similar
sharp
object
so
as
not
to
damage
contents
.
The
AC
power
cord
and
remote
pendant
control
cord
can
be
damaged
by
a
sharp
object
.
When
opening
the
container
,
be
careful
that
any
loose
items
or
hardware
are
not
discarded
with
the
packing
material
.
Check
the
contents
of
each
package
against
the
packing
list
.
Examine
the
MRR
1000
unit
for
any
signs
of
shipping
damage
such
as
broken
,
missing
or
loose
hardware
,
damaged
or
deformed
com
-
ponents
.
File
claims
immediately
with
the
carrier
if
damage
or
loss
is
detected
and
notify
the
nearest
Eaton
'
s
Electrical
Service
and
Systems
Office
.
3.2
Handling
The
MRR
1000
unit
shipping
containers
are
not
designed
to
be
handled
by
a
fork
lift
truck
.
If
containers
must
be
moved
for
any
sig
-
nificant
distance
,
it
is
suggested
to
use
a
suitable
dolly
or
hand
truck
to
move
the
approximately
40
lb
(
18
kg
)
package
.
3.3
Storage
Because
of
electric
circuits
inside
the
unit
,
as
well
as
moving
parts
,
it
is
essential
to
keep
the
remote
racking
device
dry
at
all
times
.
If
exposed
to
water
or
rain
,
performance
of
the
device
cannot
be
guar
-
anteed
and
will
void
the
warranty
.
If
the
unit
is
to
be
placed
in
stor
-
age
,
attention
should
be
given
to
keeping
the
unit
in
a
low
humidity
environment
.
Ensure
the
unit
is
free
from
damage
and
is
satisfac
-
tory
operating
condition
prior
to
storage
.
