⃝Electrical work must be done by competent persons.
⃝Do not place the ACB in such an area that is subject tohigh temperatures, high humidity, dusty air, corrosive
gasses, strong vibration and shock, or other unusual
conditions. Mounting the ACB in such an area could
cause a fire or malfunction.
⃝Be careful to prevent foreign objects (such as debris,
concrete powder, dust, chippings, and iron powder) andoil or rain water from entering the ACB. These materials
inside the ACB could cause a fire or malfunction.
⃝Prior to commencing any work on the ACB, upstream
circuit breaker or the like to isolate all sources of power/
voltage. Otherwise, electric shock may result.
⃝Fix the draw-out cradle of the ACB firmly on a ﬂat, levelsurface using mounting screw. Otherwise, the draw-out
operation may cause the breaker body or the draw-out
cradle to fall, resulting in damage to the ACB or personal
injury.
⃝For 4-pole ACBs, be sure to connect a 3-phase, 4-wireneutral conductor to the N-phase pole (on the right end).
Otherwise, an overcurrent may hinder the ACB fromtripping, resulting in a fire.
■ Transportation Precaution

Danger⃝Never stand under the ACB that has been lifted orsuspended a lifter of lifting attachments. The weight of
the ACB may cause sereious injury.
■ Operation Precaution

Danger⃝Never touch live terminal parts (main terminals or control
terminals). Otherwise, electric shock may result.
⃝Do not leave the ACB body in the draw-out position.
If the ACB body is accidentally dropped, its weight may
cause serious injury.
[Meaning of indication]

DangerA danger notices with this symbol indicatesa potentially hazardous situation which, if not
avoided, may result in death or serious injury.

CautionA caution notices with this symbol indicatesa potentially hazardous situation which, if not
avoided, may result in minor or moderate injury
and/or property danage.

Reset button

Mechanical reset
setting dial

The mechanical reset is an interlock function that prevents the ACB from being ON again
if it has been tripped due to an over-current release, until the reset button is pressed after
eliminating the cause.
The mechanical reset can be enabled simply by setting the mechanical reset setting dial on
the front of the ACB to “MANUAL”.

● New closing spring charge indicator display
The previous product only displayed the charge status of the closing spring, but
now also shows whether or not the ACB can be closed.
This provides a visual indication that the ACB is not in a ready to close state after the interlock orundervoltage trip device has been activated, a feature that was not available with the previous product.

DISCHARGED● The safety functions below are from the previous product① No extra arc space required for clearance (For draw-out type)
Almost all arc energy is dissipated inside when tripping, so there is no need to include space
for arc gases on the upper part.

② Double shunt trip devices
Two continuously-rated shunt trip devices can be mounted, allowing backup trip operation to be built.
This makes it suited to critical circuits where reliability is required.

● Can be used with reverse connections like the previous product.
Power receiving and distribution from either top or bottom terminals.
● Quick connection terminals used forcontrol circuit terminals
Eliminates the need to tighten screws with ascrewdriver, making connection work much faster.

Accessories for Draw-out Type

Main circuit safety shutters

Key lock on withdrawn position

The main circuit safety shutters automatically conceal
the main circuit contacts on the draw-out cradle whenthe ACB is drawn out.
• The line side and load side shutters operate
independently, and can be separately padlocked in
the closed position for safety.
• Each line side and load side can be locked with up to
three padlocks (with ø6 hasp).

Locking device that prevents
ACBs from inadvertently being
drawn out. Allows units to belocked in the CONNECTED,TEST or ISOLATED positions.
Up to two keys can be installed,
and can be selected from ﬁve
types: Cylinder, Ronis, Proﬂux,
Kirk, or KLS.

Mal-insertion prevention device
Interchangeability exists within the TemPower PRO
series of ACBs. This is the device to avoid that adifferent speciﬁcation of ACB is placed into the
Drawout cradle. This device is capable ofdistinguishing ten different breaker bodies.

Body sensor
Outputs the ACB’s withdrawn position (TEST,CONNECTED) to Over-Current Release (OCR). Using
this together with a communication module allows thewithdrawn position of the ACB to be checked remotely.
＊Cannot be used for modules mounted with standard
type over-current releases.

Types of Mounting

Draw-out type
Maintenance and inspection are easy. Consists of abreaker body and a draw-out cradle, where the drawout
cradle is ﬁxed in the switchboard and only the breaker
body can be drawn out or removed. There are four breaker
body positions: CONNECTED, TEST, ISOLATED, and
WITHDRAWN.

1 CONNECTED position

Fixed typeThis type of ACB has no draw-out cradle and is designed
to be directly mounted in the switchboard.

Terminal arrangements■Main circuit terminals
The design of boards is simple.
Three types of connection methods are available (verticalterminals, horizontal terminals, and front connections).
The vertical terminals and horizontal terminals can bechanged from vertical to horizontal and from horizontal
to vertical, by simply removing two bolts. Different typesof terminal arrangements can be speciﬁed for the line
and load sides. (AX120S and AX120H only have verticalterminals).
Vertical terminals

Both the main and control circuits are connected for normal
service.

2 TEST position

The main circuit is isolated
and the control circuits areconnected.
This position permits operation tests without the need for
opening the switchboard panel door.

Horizontal terminals

3 ISOLATED position

Both the main and control circuits are isolated.

Front connections

4 WITHDRAWN position

The breaker body is fully withdrawn from the draw-out
cradle.

Trip Devices

Continuously-rated shunt trip device
Continuously-rated shunt trip device can remote controll to operate the ACB to “OFF” electrically.
The continuous-rated shunt trip device allows the ACB to be turned OFF when an external protection relay against
overcurrent or reverse power is activated.
Because of its continuous rating, it can also be used as an electrical interlock for the ACB.
＊Two shunt trip device can be installed to ensure the tripping operation. In the unlikely event that one of the shunt
trip devices fails to operate due to the disconnection of wire or other cause, the other shunt trip device can beused for reliable trip operation. (In this case, Undervoltage trip can not be ﬁtted.)

2095Undervoltage trip device
The undervoltage trip device (UVT) trips the ACB when the control voltage drops below the opening voltage. Whenthe control voltage is restored to the pick-up voltage, the ACB can be closed. The pick-up voltage is ﬁxed to 85% of
the minimum rated voltage.
The undervoltage trip device (UVT) is available in two types. The instantaneous type trips the ACB instantly when
the control voltage drops below the opening voltage. The delay type (coming soon) does not trip the ACB instantly,
but trips the ACB when the control voltage remains below the opening voltage for a certain period of time.
The delay type has the undervoltage trip device controller (UVT controller) and the relay terminal mounted on theside of the circuit breaker. (For the details, please refer to the outline dimensions.)

Zone interlock
The zone interlock function can be enabled for the corresponding function when the Over-Current Release (OCR) is
compatible with short time-delay trips or ground fault trips.
If the zone interlock is enabled, a signal is output to upstream ACB if a downstream ACB detects a current greaterthan the pick-up current (Isd or Ig).
When the upstream ACB detects a current greater than the pick-up current (Isd or Ig), the signal from thedownstream ACB is veriﬁed and if the upstream ACB receives the signal, it trips with the set tsd or tg time limit. If nosignal is received, it trips with the same time limit as an instantaneous trip.
This function is not only used for linking TemPower PROs together, but can also be used for linking TemPowerPROs and TemBreak PRO Smart circuit breakers, or TemPower PROs and TemPower2 air circuit breakers.

＊Note 1) : Thermal safe protection characteristics refer to the overheating
protection characteristics of the ACB.
These characteristic are identical to the characteristic curve for longtime delay trip characteristics (Thi) with Ir=In, tr=30.0 s.
In the area where the operating time of thermal safe protection
characteristic is faster than the operating time of Long time delay trip
characteristic, the thermal safe protection characteristic takes priority
and the ACB is tripped.

Special environment

The standard environment for ACBs is as follows:

Tropicalization (Fungus and moisture treatment)

Storage temperatureSpecify this treatment when the ACB is used underhigh temperature and high-humidity conditions.

Max. permissible storage temperature +60°C,
Min. permissible storage temperature –20°C.
The average temperature for 24 hours must
not exceed 35°C.

Operating temperature Max. permissible operating temperature+40°C,
Min. permissible operating temperature –5°C.
The average temperature for 24 hours must
not exceed 35°C.
Relative humidity

Below 85%

Vibration / ShockNot subjected to abnormal vibrations orshocks.

Attitude

Below 2000m

Atmosphere

Excessive water vapor, oil vapor, smoke,
dust, or corrosive gases must not exist.
Sudden change in temperature, condensation,or icing must not occur.

Mounting condition

According to the instruction of mounting on
the catalogue and manuals.

Guideline for renewal 	Expected service life is 15 years under the
standard environment.

54

Ambient temperature	Max. permissible ambient temperature +60°C
Relative humidity	Max. permissible humidity 95% rel(No condensation)

Cold climate treatment
Specify this treatment when the ACB is used in cold
areas.
Storage temperature	Max. permissible storage temperature +60°C,
	Min. permissible storage temperature –40°C(No condensation)
Operating temperature	Max. permissible operating temperature +40°C,
	Min. permissible operating temperature –25°C

Anti-corrosion treatment
Specify this treatment when the ACB is used in a
corrosive atmosphere9

Busbars connection

When two busbars are connected to a terminal stud of ACB, sandwich the terminal stud between the two busbars toutilize both surfaces of the terminal. A spring and plain washer must be used in conjunction with the busbar bolt andnut as below.

10 Recommendation for Busbars connection
The busbars to the ACB should be ﬁrmly supported near the ACB terminal. Fault currents ﬂow through the busbars
developing a large electromagnetic force between the busbars. The support must be strong enough to withstandsuch forces and ensure the enough insulating distance. The ACB should not be relied on as single support.

Latch Release Coil (LRC)＊9 : Connecting continuously-rated shunt trip devices and operation circuits.
Ensure that the cables connecting the switch with terminals ‚3, ‚8 and ⁄0 are 5 m
or less in length, and keep them as far away as possible from power supply cables.
If the cables exceed 5 m in length, or if using a AC380–480V rated voltage
continuously-rated shunt trip device and latch release coil, use either of the following
connection methods, as there is the risk of incorrect device operation caused bystray capacitance between cables.
1) Connect a relay near the ACB, and control the relay remotely.
2) Short-circuit the terminals as shown below.
Note that there will be an inrush current at the switch when using this connection
method, so select a switch capable of handling the inrush current values in thetable below.

Latch Release Coil (LRC)＊8 : Connecting continuously-rated shunt trip devices and operation circuits.
Ensure that the cables connecting the switch with terminals ‚3, ‚8 and ⁄0 are 5 m
or less in length, and keep them as far away as possible from power supply cables.
If the cables exceed 5 m in length, or if using a AC380–480V rated voltage
continuously-rated shunt trip device and latch release coil, use either of the following
connection methods, as there is the risk of incorrect device operation caused bystray capacitance between cables.
1) Connect a relay near the ACB, and control the relay remotely.
2) Short-circuit the terminals as shown below.
Note that there will be an inrush current at the switch when using this connection
method, so select a switch capable of handling the inrush current values in thetable below.
