產品型號：3TH4355-OA

SIEMNES Siemens 3TH4355-OA fuse low-voltage contactor

西門子接觸器：

SIRIUS（進口）3RT2 /3RT1 接觸器可滿足 250 kW 內電機的各種應用需求。在S00 至 S12 規格的產品中，除了 3 極標準接觸器外，還可以提供真空接觸器、用于與控制器連接的接口繼電器、4 極接觸器以及***高至 4 kW 的微型接觸器。新推出的 S00 和 S0 規格 3RT2 接觸器應用尤其靈活，除螺釘連接外，還可提供彈簧式和環形接線端子，且 S00 和 S0 規格通用相同的輔助觸頭。特殊的 UC 接觸器可用于交流或直流電壓控制，并且線圈功耗更低。S0 規格接觸器上已集成兩個輔助觸頭，所有輔助觸頭采用雙斷點結構，接通可靠性更高。尤其值得一提的是，S00 和 S0 規格的接觸器通過直接加裝功能模塊可方便地組裝成可逆或星-三角起動組合。這些功能模塊可選擇帶 AS-i 或 IO-Link 接口，大大簡化控制回路接線。在安全應用方面，3RT2 系列還提供一些新功能，比如使用安全連接模塊可組裝成符合 ISO13949-1 標準 PLe 或者 IEC62061 標準 SIL3 的接觸器組合。

主要優點：

 

百萬次電氣使用壽命，操作可靠性高

輔助觸點采用雙斷點結構，接通能力高達 1 mA / 17 V，滿足固態回路應用需求

良好的內部密封性，在粉塵、潮濕環境下仍可保證可靠工作

尺寸小巧，45 mm 寬度額定電流可達38 A

輔助觸頭、浪涌抑制器等主要附件的裝卸無需任何輔助工具

提供全面的 CAx 輔助設計文檔，方便地滿足不同層次的設計需求

符合 CCC / CE / UL / CSA 等認證要求，設計可靠性高

7 A 起每個電流等級均可提供 2 級能耗產品，節能環保

Siemens contactor:
The SIRIUS (imported) 3RT2/3RT1 contactor can meet various application requirements of motors within 250 kW. In products with specifications S00 to S12, in addition to 3-pole standard contactors, vacuum contactors, interface relays for connecting to controllers, 4-pole contactors, and * * * micro contactors up to 4 kW can also be provided. The newly launched S00 and S0 specifications of 3RT2 contactors are particularly flexible in application. In addition to screw connections, they can also provide spring and ring terminal blocks, and the S00 and S0 specifications share the same auxiliary contacts. Special UC contactors can be used for AC or DC voltage control with lower coil power consumption. Two auxiliary contacts have been integrated on the S0 specification contactor, and all auxiliary contacts adopt a double breakpoint structure, resulting in higher connection reliability. It is particularly worth mentioning that contactors of S00 and S0 specifications can be easily assembled into reversible or star delta starting combinations by directly installing functional modules. These functional modules can be selected with AS-i or IO Link interfaces, greatly simplifying control circuit wiring. In terms of safety applications, the 3RT2 series also provides some new features, such as the use of safety connection modules that can be assembled into contactor combinations that comply with ISO13949-1 standard PLe or IEC62061 standard SIL3.
Main advantages:
Millions of electrical service lives and high operational reliability
The auxiliary contact adopts a double breakpoint structure, with a connection capacity of up to 1 mA/17 V, meeting the requirements of solid-state circuit applications
Good internal sealing ensures reliable operation in dusty and humid environments
Compact size, 45 mm width, rated current up to 38 A
The loading and unloading of main accessories such as auxiliary contacts and surge suppressors do not require any auxiliary tools
Provide comprehensive CAx aided Software design debion to meet design requirements at different levels
Complies with CCC/CE/UL/CSA certification requirements, with high design reliability
Starting from 7A, each current level can provide Level 2 energy consumption products, which are energy-saving and environmentally friendly
