NA8G Electric Fixed/Drawer Air Circuit Breakers For Equipment Line Protection
Product
Description:
The
NA8G
series
air
circuit
breaker
(“circuit
breaker”
in
short),
with
rated
current
from
200A
to
6300A
and
rated
operating
voltage
of
415V,
690V
AC,
is
suitable
for
operation
under
50Hz/60Hz
AC
and
is
mainly
used
in
distribution
network
for
power
distribution,
and
to
protect
power
line
and
power
equipment
from
various
faults
such
as
overload,
short
circuit,
undervoltage
and
single-phase
ground.
The
circuit
breaker
is
a
combination
of
aesthetic
appearance,
high
breaking
capacity,zero
flashover
and
multiple
intelligent
protection
features
.
It
can
provide
selective
protection
with
accurate
operations,
to
avoid
unnecessary
black
out
and
guarantee
reliable
power
supply.
Standard:IEC/EN
60947-2.
Operating
Conditions
and
Environmental
Suitability:
NA8
products
can
operate
normally
at
the
following
temperature.
Electric
and
mechanical
characteristic
applicable
for
ambient
temperature
-5℃~+40°℃(certified),
and
also
peripheral
ambient
temperature
-45℃~+70℃(M
type
),
-20℃~+70℃(H
type
).
Storage
conditions:
Applicable
for
-45℃~+70C.
NA8
may
resist
against
the
following
electromagnetic
interference:
EMI-generated
overvoltage;
Overvoltage
caused
by
environmental
disturbance
or
distribution
system;
Radio
wave
(radio,
interphone,radar,
etc.).
Static discharge of terminal users NA8 circuit breakers have successfully accredited through the EMC test specified in the following standards: IEC/EN 60947-2.
The above tests may ensure: no false tripping fault, tripping time not interrupted.
Protection grade: Front IP20,other sides IPO0
