Completely renewed electronic circuit breakers, ranging from
Among the industry’s smallest breakers

130㎜

Models sizing 100AF or 125AF are the industry’s smallest,
measuring just 90 mm width, 130 mm height, and 68 mm depth
for 3-pole types. 630AF models are of the same dimensions as
400AF versions: 140 mm width, 260 mm height, and 103 mm
depth for 3-pole types. Their compactness helps space-saving in
distribution switchboards.

Smart MCCBs facilitating energy saving
Our new smart circuit breakers are capable of acquiring,
displaying, and transmitting circuit information.
They help consolidate and reduce devices needed for energy
management systems used at buildings and factories.

Remote display★Remote display of circuit information
The TemViewPRO Remote display (optional) can be connectedto the smart circuit breakers using a single cable and easily
attached to the switchboard panel. It has a back-lit LCD displaythat is highly visible even in dark places.

★Centralized control of circuit information
The TemComPRO Communication Module (optional) allows
network communication of circuit information.
A system can be easily developed owing to the Modbus RTU
communication protocol.
The TemComPRO can be mounted on a DIN rail with a snap-on
mechanism and wired using connectors, so it is easy to install
for additional installation.
With use of a support, the module can also be mounted on theside of the circuit breaker.

★Zone interlock function mitigates circuit damage

If an accidental short circuit or ground fault occurs in a
selective coordinated circuit with short time-delay protection
and ground fault protection, the circuit breaker in theimmediate upstream of the accident spot can be protected byan instantaneous trip triggered as a result of deactivation oftime delay settings, consequently alleviating thermal andmechanical damage to the circuit at the time of accidental
short circuiting. Linkage can be established among smart
circuit breakers ranging from 100AF to 630AF, as well as
between the smart circuit breaker and the TemPower2 air
circuit breaker.

100AF to 630AF, provide much improved user convenience.
Advanced standard series electronic circuit breakers★Protection settings of standard series can be
adjusted using multiple dials in place of conventional two dials, enabling flexible configuration ofprotection to meet a wide variety of needs.
★The pre-trip alarm function, which was optional forthe previous series, is now available as a standardfeature. With this, the load current can be constantlymonitored.
★Settings for long time-delay can be configured byconventional rated current adjustment; in addition,
it can be set to 91% and 100% of the rated current, in
1% increments. This allows fine tuning to suit theload conditions to be applied.
★Also equipped with a temperature self-monitoringfunction.
When the temperature of the circuit board inside theover-current protective device exceeds 105°C, a LED
lamp lights up in red to indicate an abnormal
operating status of the breaker.

The following types of circuit information can be acquired.
There is no need to install in-panel instruments and incidental
connecting wires in the energy management system.
•Current •Voltage •Wattage •Watt-hour •Power factor•Frequency •Total harmonic distortion •Demand current•Demand wattage★Precision measurement

Rogowski coils are used for current sensors.
Measurement is now possible with higher precision thanprevious series.
Reading errors complying with the international standard IEC
61557-12 were adopted to realize enhanced measurement
accuracy: ±1% for electric current, ±0.5% for voltage, and ±2%
for wattage.
This allows precise monitoring of energy use conditions.

★Great visibility

An OLED display panel is used forthe display to indicate
measurement values. Also, highvisibility is ensured by use ofsymbols representing the items tobe displayed.

ACP★Excellent operability

A joystick is used for switchingdisplay screens and configuring
settings.
User-friendliness improved incomparison with push-button
operation adopted inconventional models.

Joystick★Status indication realized by smart AX/AL switch

Smart AX/AL switch

With a special AX/AL switch installed, the number of times theauxiliary switch and alarm switch were activated can beindicated on the display of the circuit breaker, and it is also
possible to transmit the activation count, along with the statusof these switches, to the network including remote displays.

The 400AF/630AF models feature a pressure trip
mechanism that leverages internal pressure
generated at the time of a short-circuit trip, and arotating double contact structure that has evolved
from the world’s first current-limiting circuit breakertechnology developed by Terasaki. Owing tosmooth contact separation realized by the rotating
double throw contact, as well as speedy cut-off by
the pressure trip mechanism, these new circuit
breakers have excellent breaking performance:
Icu /Ics =110kA/110kA（415V AC）.

Safety
Safety inherited from TemBreak2

The safety-conscious functions and design features of the TemBreakPRO were taken over from the TemBreak2 series.

OPENING

ION

Opening force is transmitted directly from the toggleswitch.

TAC

Not in the OFF position
Cannot be locked OFFAs well as being a spring-based switching mechanism,with the forced OFF mechanism, the main contact ismoved directly by the operating force from the toggle atthe time of OFF operation.
It can be used as an emergency stop switch for machines
which comply with IEC60204-1. Even if the internal springmechanism is damaged, the plug-in base can be turned
OFF, meaning that it is safe.

TThe isolation capability means that, as long as the maincontact is closed, the toggle is not in the OFF position andcannot be locked at the OFF position.
The toggle being in the OFF position hence shows themain contact is open and personnel are not exposed toelectrical shock hazard when working in the load side.

Isolation capability

Main contact closed

Enhanced Insulation
The risk of touching live parts has been minimized bydesign. If the toggle is broken by accident or misuse, nolive part is exposed.
Moreover, 400AF and 630AF models adopted a pole unit
structure comprising contacts and arc chambers housedin plastic cases and allocated to each pole.
This helped improve insulation performance betweenpoles.

Pole unit

Easy-to-understand status indication
The indicator clearly shows Red when the circuit breaker is
ON and Green when the breaker is OFF. No color
indication means the device has tripped.
This design prevents misperception of breaker statuswhen seen from any angle, thus ensuring safety.
