Breaking Contacts
TemPower 2 is the world's first Double Break ACB, having two breaking contacts per phase. The unique pole structure means that the short-time withstand rating (Icw) is equal to the service short-circuit breaking capacity (Ics) for all models.
Packing Density
You can increase switchboard packing density using the smallest one second rated ACB on the market. The fixed version is 290mm deep, the drawout version is 345mm deep.
Reliability
Double Break contacts increase service life. Electrical and mechanical endurance ratings are the best available, and exceed the requirements of IEC 60 947-2.
Double Quick Opening
TemPower 2 ACBs clear short-circuit faults in less than 30ms. That%u2019s twice as fast as most ACBs.
Double Opening and Closing Coils
Now you can extend control system redundancy to an ACB. Double coils allow designers to implement back-up tripping and closing systems.
Double Neutrals
How do you make a system harmonic proof in the face of increasing triple-N harmonic currents? Terasaki have launched the first Double Neutral ACB. The AH-60DN will carry 10,000A of neutral current.
Protection Characteristics
TemPower 2 is the only ACB which offers time-current characteristics to 3 different standards:
IEC 60 947-2 (low voltage circuit breakers)
IEC 60 255-3 (electrical relays)
Lloyds Register of Shipping (for marine generator protection)
All models have LSI protection.
Double Insulation Properties
All operator controls and accessory locations are double insulated from the main phases.
ReduceTime to Repair
Modular construction means that each pole of the TemPower 2 ACB can be replaced in about 15 minutes - by the user. This unique feature will reduce downtime for end-users.

Terasaki developed its original breaker for the first time in Japan in 1947.
Since then, the company has been offering, as a specialized breaker
manufacturer, the most advanced breakers not only to the Japanese market, but
also to the world markets.
The TemBreak series of Moulded case circuit breakers, which is evaluated as
highly reliable by our customers, has been improved from time to time for better
performance through Terasaki's advanced technologies.
In 2000, the TemPower 2 series was released to replace the Tempower series of
air circuit breakers, which had received high reputations for many years. This
new series consists of small, high-performance air circuit breakers featuring
advanced information and communication capabilities.
Terasaki is ready to meet the customers' requirements in the 21st century through
its diversified model lineup and its broad range of enhanced products.

Application:
Miniature circuit breakers ETIMAT DC are used for protection of conductors in direct current
electric circuits. 1-pole circuit breakers are used for voltages up to 220 V d.c. and for higher voltages (up to
440 V d.c.) 2-pole circuit breakers with poles connected in a series. When connecting the MCB ETIMAT DC
man must pay attention to polarity. If connected in a wrong way, the MCB can be destroyed. You cannot use
two 1-pole MCBs instead of one 2-pole MCB.

If a magnetic relay coil is opened and closed near an electronic circuit, malfunctioning of the electronic circuit could be induced by a surge voltage. The UN-SA type surge absorber suppresses the surge voltage when the coil is opened and closed. In addition to the general varistor type and the CR type that lays importance on suppressing the induction voltage when starting, the type with operating indicator (varistor type), and the varistor type with CR are available.

No electrical system can do without circuit breakers, as they are the 'stop' signs acting when too much current is flowing through electrical wiring.
In fact, they are essential devices and one of the most important safety mechanisms for the prevention of dangerous situations. The value of circuit breakers depends on which appliances are connected. You can either order a ready-made switchboard with the most common circuit breaker values, or give the installer or distributor a list of your specific values for a tailor-made solution.

Yaskawa SF6 gas rotary-arc circuit breakers are rated for applications in power generating plants, substations, and industrial plants at 3.6kV to 15kV. Yaskawa SF6 gas rotary-arc circuit breakers are safer to operate than vacuum and other competitive types because a two-stage pressure switch in each of the interrupters continuously monitors the gas pressure. This series of Yaskawa SF6 gas rotary-arc circuit breakers offer excellent interrupting characteristics, comparable to air-magnetic breakers, with continuous current ranging from 600 to 3000 amps. In addition, the surgeless nature of the current interruption eliminates the need for surge arrestors to dampen voltage spikes related to current chopping and switching surges. This feature makes the Yaskawa SF6 gas rotary-arc circuit breakers ideal for the protection of motors, capacitors, and transformers. This series of circuit breakers conforms to applicable ANSI, IEC and JEC st

With the CT contactor series Schaltbau is introducing a new and innovative contactor concept to the market: power contactors in a completely new style and design, specially developed for the sophisticated requirements of the railway industry. The outstanding technical feature of this new product is the innovative combination of electromagnetic and permanent-magnetic blowout technology for electric arc control. The successful combination of these two principles greatly improves both switching functionality and reliability and forms a practical and economically impressive device concept.
The innovative core of the new CT series is the electric arc control technology: in contrast to contactor concepts purely based on electromagnetic blowout, the arcs created at the moment of switching off are ignited in powerful permanent-magnetic blowout fields. Thus the dwell periods in the contact zones are limited to an absolute minimum. This leads to a significant reduction in arc-related burn-up when switching off. The lower degree of wear on the contacts makes it possible to greatly increase maintenance intervals.
The arcs blown out of the contact zones act as wear-free switches in the next phase: the skipping to adjacent arc modulators activates the blowout coils, making switching-off procedures independent of the direction of the current from that moment onwards. In the final phase the arcs pass through an arc chute, are stretched across the divergently arranged modulators and then effectively extinguished in a ceramic chamber. The special design of the extinguishing process reduces the discharge of ionised gases from the arc chute.
