Air Circuit Breaker
Presentation
NIRAPOD 4 air circuit breakers are designed and made
incorporating universal control unit NIRAPOD4.02M/H
having protection, control & measurement functions. They
may be installed in main LV switchboards as incoming units,
main and secondary outgoings. NIRAPOD 4 acb offers a
complete range with a large selection of performance level:
J ratings from 800 to 6300 A AC,
J breaking capacity from 40 to 100 kA rms;
J operational voltages 690V AC 1000V DC

are
equipped
with
microprocessor- based electronic control units. All the
protection functions are powered by the AC system and
no auxiliary power supply is required. The same is true
for most of the complementary functions.
NIRAPOD4.02M/H control units measure the true rms
value of the current Voltages cosϕ, Hz, kW, reading and
are therefore not affected by harmonics that may be
present on the system.
Operating safety
The insulating casing of NIRAPOD 4 circuit breakers
provides for:
NIRAPOD 4 circuit breakers comply with all
the major international standards:
J user safety:
j double insulation on the front face (class II)
J International standard IEC 947-2 They also comply with
j auxiliary circuits in a compartment insulated from the
the following national standards:

j each pole is effectively isolated in its own housing

j limitation of external disturbances

Positive contact indication
The position indicator cannot indicate "open" unless the
poles are effectively separated by the required distance.
The circuit breakers automatically open during racking in
and out.
Tropicalisation
reliability
As standard, NIRAPOD 4 circuit breakers are designed
J NIRAPOD 4 circuit breakers comprise ten times fewer
for tropical conditions with 95% relative humidity at 45oC
parts than traditional devices. They are easier to produce
or 80% at 55oC, hot and humid climate conditions. They
and more reliable.
also comply with the following standards:
J the design of Adex circuit breakers is modular with delayed
I IEC 68-2-30 damp heat
differentiation (highest possible number of common parts on
I IEC 68-2-2 dry heat
all models). The result is shorter delivery times and

Standards
Ease of installation
NIRAPOD 4 is a complete and rationally designed range.
J 10 ratings;
J wide breaking-capacity levels;
J 1 control units covers all the protection & measurement
functions
J a complete range of auxiliaries and accessories;
J numerous versions (three and four-pole devices, fixed and
drawout versions, etc.).
NIRAPOD 4 circuit breakers are easy to incorporate in
switchboards
J a single frame size from 800 to 3200 A, thus making for
standardised columns;
J an upper safety clearance equal to zero due to the
arc-chute cover, on both the fixed and drawout versions;
J built-in measurement functions in the control units;
J auxiliaries are the same for the entire range and may be
easily implemented (only a screwdriver is required).
NIRAPOD 4 circuit breakers are easy to connect to the main
distribution system.
J all types of connections are available (horizontal and
vertical terminals, front and mixed connections);
J connections are possible with bars of any thickness
J connection to the input power source is possible on the
upper or lower terminals of the circuit breakers.
Due to their small size, NIRAPOD 4 circuit breakers can
replace most existing circuit breakers.
IEC 947-2
This standard provides the user with a better guarantee
concerning quality and performance.
Circuit breakers are subjected to tests that are more
representative of real operating conditions.
Definition of the terms breaking capacity:
IEC947-2 also clarifies the notion of breaking capacity.
J Icu: the ultimate breaking capacity, which must be greater
than or equal to the 3-phase short-circuit current at the
point of installation of the circuit breaker, a value unlikely
to be reached under real conditions;
J Ics: the service breaking capacity, generally expressed as
a percentage of the ultimate breaking capacity (25,50,75
or 100% of Icu). It corresponds to a short-circuit current
that is more likely to be reached under real conditions.
The circuit breaker must continue to operate normally after
having interrupted a current equal to Ics several times;
J Icw: short-time withstand current for circuit breakers
belonging to category B (category B refers to circuit
breakers with time discrimination and category A to those
without time discrimination).
Furthermore, IEC947-2
technological advances:
takes
into
account
recent
J suitability for isolation recognised for circuit breakers
having passed special electrical and mechanical test:
J industrial earth-fault circuit breakers covered by an
appendix;
maximum dependability
All NIRAPOD 4 circuit breakers are also disconnectors
(suitable for isolation) as specified by IEC 947-2. They bear
the corresponding symbol on the front cover:
J definition of tests designed to ensure coordination between
two circuit breakers.
This characteristic considerably increases the dependability
of the circuit breaker.
The conditions specified by IEC 947.2 for this function are:
J positive contact indication;
J impulse withstand; 8kV at sea level;
J very low leakage current, checked on new circuit breakers
and on circuit breakers subjected to tests representative of
the end of service life.
Moreover Adex circuit breakers have a double- insulation
front face (i.e.a class II device) allowing control from the
outside.
installation
NIRAPOD 4 circuit breakers may be installed on horizontal
metal surfaces or on rails. They are secured by four points
accessible at the bottom of the chassis (drawout versions) or
on either side of the circuit breaker (fixed versions.) A single
door cut-out is required for the entire range and provides
access to NIRAPOD 4 controls.

The addition of the electrical operating mechanism does
not alter circuit breaker dimensions.
Added to the manual charging mechanism, a motor charges
and automatically recharges the stored-energy spring upon
breaker closing making possible fast O-C-O cycles
Opening and closing operations are instantaneous.
The manual mechanism remains available for emergency use.

earth fault protection
This earth fault protection is designed to protect the installation
against the risks of fire due to high earth faults (not to be confused
with schemes designed for the protection of persons against
electrical shock).
Two types of earth protection are available:
J residual current type (T): the control unit calculates the vector
sum of the phase and neutral (if distributed) currents
J source ground return type (W): the control unit acts directly on the
signal received from an external current transformer installed on
the source earthing circuit.

Communication Network: Nirapod4.02H Controller
Through Modbus-Rtu, Profibus-DP or Device-Net.
The RS485 connection, address and baud rate can be set
through the programmer.
The “four remote” function, remote measuring, remote
communication, remote control, and remote modifying can be
realized through the communication interface.
ST-DP is the communication module. The master station card
is SIEMENS’s CP5X11，RTis the resistance of the network
terminal，usually 150 ohm.

NIRAPOD 4.02H
Modbus
Communication Module
To be used with the H type controller for converting from
Modbus-Rtu to Profibus -DP. Auxiliary power is AC/DC 220V
Dimension diagram：
Communication Interface T04
To be used in switchboard for communication connection with
the breaker.
（Encoded as 2 in the Switchboard diagram）
Communication Line
For the connection with various communication terminals, A
shielding twisted-pair is OK for this purpose. When ST-DP is
used, T215-01 is needed；when ST-DN is used, T415-01 is
used.
