TemPower2 economical series air circuit breakers excel incost performance.
TemPower2 economical series including 630A
to 1600A frame breakers
H:460

The breakers of this series are the same in enclosure size. Compact andfully equipped with essential functions, this series excels in cost performance.

D:272
W:356

The ACB panel cutout identical for
all the TemPower2 series breakers
The same front panel cutout size for economical, standard, and high-fault series allows easy designing ofswitchboards.

Increased accessibility fromthe front
It enhances ease of installation, operation, andmaintenance.
Accessory fitting(Removing the front cover enables
replacement of internal parts.)

Enhanced selectivity

Connection to the main circuit(for front connections)

Connection to thecontrol circuit
Manual operation

Full selectivity can be achieved as the rated breaking
capacity is identical to the rated short-time withstandcurrent.

Over-current release (OCR)
featuring operational ease
Simply using two dials of the OCR, one for selecting the
rated current and the other for selecting a protection
characteristic, allows you to set up the OCR. Coming
standard with six protection characteristics, the OCR
provides optimum selective coordination with upstream
high-voltage breakers or relays and downstream breakers or loads.

The double insulated design ensures that most accessories canbe safely and easily, installed by the user. Control and auxiliary
switch terminals are mounted at the front on the ACB body foreasy access. For the connection to the main circuit, it is easy toaccess from the front for the front terminals using optional attachments. Due to the increased level of harmonics within the distribution network, the neutral phase is fully rated as standard.

Types of Mounting

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 ACBs come standard with horizontal terminals. The user can change horizontal terminals to vertical or front terminals using
optional attachments for any last minute alterations.

£Horizontal terminals£Vertical terminals£Front connections■ Control circuit terminals
Control circuit terminals are front located to allow easy wiring/access.
• The terminal blocks (for auxiliary switches and control circuits) are positioned on the top of the ACB front panel and can beaccessed from the front for wiring.
• M4 screw terminals are standard.

2Spring Charged Operation

Manual charging type
For this type of ACB, the closing springs are charged by means of the spring charging handle. ON/OFF operation of the ACB isperformed by means of ON/OFF buttons on the ACB.
■ Charging the closing springs
Pumping the spring charging handle by hand charges the closing springs.
■ Closing the ACB
Pressing the ON button on the ACB closes the ACB.
■ Opening the ACB
Pressing the OFF button on the ACB opens the ACB.
The ACB cannot be closed as long as the OFF button is pressed.

Motor charging type
For this type of ACB, the closing springs are charged by means of a motor. ON/OFF operation of the ACB can be performed
remotely.
A manual charging mechanism is also fitted to facilitate inspection or maintenance work.
■ Charging the closing springs
A motor is used to charge the closing springs.
When the closing springs are released to close the ACB, they are automatically charged again by the motor for the next ON
operation.
■ Closing the ACB
Turning on “remote” ON switch enables the ACB to be remotely closed.
• Anti-pumping mechanism
Even if the ON switch is kept on, ACB closing operation is performed only once.
To close the ACB again, remove the ON signal to reset the anti-pumping mechanism and then reapply the ON signal.
• If ON and OFF signals are simultaneously given to the ACB, the ON signal is ignored.
■ Opening the ACB
For opening the ACB remotely, specify the shunt trip device (See P. 9) or the undervoltage trip (See P. 9).

2Ground fault trip function GF
The peak value sensing is used (the residual current of each phase is detected).
The GF pick-up current is set at 20% of the rated current [In] with 0.2 sec. time-delay. The GF protection can be disabled by a DIP
switch on the O.C.R.
When using a 3-pole ACB in a 3-phase, 4-wire system, be sure to use an optional CT for neutral line (see P. 12).

3Pre-trip alarm function PTA (Optional)
The pre-trip alarm function provides an alarm signal via the alarm contact (1a-contact) when the load current exceeding a predetermined value lasts for a predetermined time.
The pre-trip alarm is automatically reset when the load current drops to the predetermined value.
Note that this function does not need the control power.

4N-phase protection function NP (Optional)
This NP function is available on 4-pole ACBs and prevents the neutral conductor from suffering damage or burnout due to overcurrent.
The NP trip pick-up current can be selected to 100% or 50% of long time-delay trip pick-up current setting [IR] by a DIP switch on
the O.C.R., and also can be disabled.

OCR test interface unit, type ANS2SOCR test interface unit ANS2S is a tool designed for checking
the functionality of type AGR-12BL over-current release. Using
this tool in conjunction with a commercially available relay tester
allows easy on-site testing of the OCR.
Be sure to use the OCR test interface unit in conjunction with arelay tester rated at 50A max.

Current transformer for neutral line (separate type)
When using a 3-pole ACB with the ground fault protection function to protect a 3-phase, 4-wire system against ground fault, install
an appropriate current transformer (CT) to the neutral line of the system.
TERASAKI can provide this neutral line CT as an option.
For the 4-pole ACB the neutral line CT is already built into the neutral phase of the ACB when the ground fault protection is fitted.

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