Auxiliary Contact Wiring DiagramThe TYCJ series of AC Contactors is the newest AC contactors currently
available in China. The products are of compact design and are small; light-weight
and energy efficient. The contactor’s magnetic system is of an optimized design,
and its iron core is made of a sealed structure to protect against intrusion by outside
objects. The accessories are connected without using any fastener parts and as such
are easy to install or dismantle.
The products can be fixed and installed using 35mm DIN rails or screws in
conformity with international standards. The wiring is by either Y- or O-type, enabling
it to be more stable and robust.TA YCC

Product features
Self-cleansing contactor
The contactor has a ball-design which moves and rubs itself when shut, thus
enabling the contactor to maintain good contact reliability as well as self-cleansing of
the oxidized film on the surface.
Slip-proof screws
All screws are of slip-proof(anti-drop) design to ensure the reliability of wire
connection.

AC接觸器（AC Contactor）是一種在電力系統(tǒng)中常見的電磁式開關(guān)元件，專門設(shè)計用于控制交流電（Alternating Current, AC）的通斷。它利用電磁力來操作一對或多對觸點，當(dāng)線圈通電時，產(chǎn)生磁力吸引動鐵，驅(qū)動觸點閉合以接通電路；當(dāng)線圈斷電時，磁力消失，動鐵返回原位，帶動觸點斷開從而切斷電流。AC接觸器廣泛應(yīng)用于電動機(jī)啟動、停止、變頻調(diào)速以及各種工業(yè)自動化控制系統(tǒng)中，其工作電壓和電流等級可以根據(jù)具體應(yīng)用場合進(jìn)行選擇。對于電氣工程人員或設(shè)備維護(hù)者來說，正確選用和使用AC接觸器是確保電氣設(shè)備安全運(yùn)行的重要環(huán)節(jié)。如果您有關(guān)于AC接觸器的具體問題或需要選型建議，請詳細(xì)說明。
