Molded case circuit breakers are used in industrial and urban low-voltage plants with operating current from 1 - 1000A. They are installed in DC and AC distribution cabinets for motor protection (motor control center), generator protection, capacitor protection and end users.

ABB集團(tuán)位列全球500強(qiáng)企業(yè)。集團(tuán)總部位于瑞士蘇黎世，并在蘇黎世、斯德哥爾摩和紐約證券交易所上市交易。ABB由兩個(gè)歷史100多年的國際性企業(yè)－瑞典的阿西亞公司(ASEA)，和瑞士的布朗 勃法瑞公司(BBC Brown Boveri) 在1988年合并而來的。

ABB group ranks among the world's top 500 enterprises. Headquartered in Zurich, Switzerland, the group is listed on the Zurich, Stockholm and New York stock exchanges. ABB was merged in 1988 by two international enterprises with a history of more than 100 years - Sweden's ASEA and Switzerland's BBC Brown Boveri.

ABB在中國參與了眾多國家重點(diǎn)項(xiàng)目的建設(shè)，如三峽電站建設(shè)和輸配電工程、南水北調(diào)工程、青藏鐵路、北京奧運(yùn)工程中的首都國際機(jī)場的改擴(kuò)建項(xiàng)目、變電站項(xiàng)目、輕軌項(xiàng)目等。此外，ABB還為亞洲最大的石化項(xiàng)目－上海賽科、廣州地鐵、上海地鐵、北京人民大會(huì)堂、上海通用汽車、寶鋼等眾多客戶提供了可靠的電力或自動(dòng)化技術(shù)解決方案。

ABB has participated in the construction of many national key projects in China, such as the construction of the Three Gorges power station and power transmission and distribution project, the South-to-North Water Transfer Project, the Qinghai Tibet railway, the reconstruction and expansion project of the Capital International Airport in the Beijing Olympic project, the substation project, the light rail project, etc. In addition, abb also provides reliable power or automation technology solutions for many customers such as Shanghai Secco, Guangzhou Metro, Shanghai Metro, Beijing Great Hall of the people, Shanghai General Motors, Baosteel and so on.

ABB 設(shè)計(jì)的2種系列的 塑殼斷路器：眾所周知的Isomax S系列和新開發(fā)的Tmax系列（在2003國際設(shè)計(jì)中，以其技術(shù)含量和環(huán)保而聞名）。此外，Tmax 更具有極高的性能水平：外形尺寸小，安裝簡單。再加上雙重絕緣，確保操作者安全。因其Tmax 斷路器的卓越性能以及脫扣器和附件的完整性，可使用在交流和直流用電工廠的主配電和子配電中。

Two series of molded case circuit breakers designed by ABB: the well-known Isomax s series and the newly developed Tmax series (famous for its technical content and environmental protection in 2003 International Design). In addition, Tmax has a very high performance level: small overall size and simple installation. Coupled with double insulation to ensure the safety of the operator. Due to the excellent performance of Tmax circuit breaker and the integrity of release and accessories, it can be used in the main distribution and sub distribution of AC and DC power plants.

Tmax 特性

Tmax characteristics

Tmax系列技術(shù)高，采用了最先進(jìn)的設(shè)計(jì)和模擬工具，保證在最小的外形尺寸上達(dá)到最優(yōu)的性能。

Tmax series has high technology and adopts the most advanced design and simulation tools to ensure the optimal performance in the smallest overall dimension.

由于滅弧室采用最新科技和能夠加快分閘速度，Tmax系列斷路器可極大地限制允通能量、減少電流峰值，從而避免裝置過熱和降低電動(dòng)應(yīng)力。

Since the arc extinguishing chamber adopts the latest technology and can accelerate the opening speed, Tmax series circuit breakers can greatly limit the allowable energy and reduce the current peak, so as to avoid overheating and reduce the electric stress of the device.

此外，Tmax系列斷路器使用了一套完全通用和標(biāo)準(zhǔn)的附件，具有很多優(yōu)點(diǎn)：減少庫存、方便靈活和使用方便。它們皆可選配(使用電流高達(dá)500A的)新型剩余電流脫扣器。(RC221, RC222, RC223)

In addition, Tmax series circuit breaker uses a set of completely universal and standard accessories, which has many advantages: reduced inventory, convenience and flexibility and easy to use. They can be equipped with new residual current release (with current up to 500A). (RC221, RC222, RC223)
