SIEMNES Siemens 3TH4355-OA fuse low-voltage contactor

西门子接触器：

SIRIUS（进口）3RT2 /3RT1 接触器可满足 250 kW 内电机的各种应用需求。在S00 至 S12 规格的产品中，除了 3 极标准接触器外，还可以提供真空接触器、用于与控制器连接的接口继电器、4 极接触器以及***高至 4 kW 的微型接触器。新推出的 S00 和 S0 规格 3RT2 接触器应用尤其灵活，除螺钉连接外，还可提供弹簧式和环形接线端子，且 S00 和 S0 规格通用相同的辅助触头。特殊的 UC 接触器可用于交流或直流电压控制，并且线圈功耗更低。S0 规格接触器上已集成两个辅助触头，所有辅助触头采用双断点结构，接通可靠性更高。尤其值得一提的是，S00 和 S0 规格的接触器通过直接加装功能模块可方便地组装成可逆或星-三角起动组合。这些功能模块可选择带 AS-i 或 IO-bbbb 接口，大大简化控制回路接线。在安全应用方面，3RT2 系列还提供一些新功能，比如使用安全连接模块可组装成符合 ISO13949-1 标准 PLe 或者 IEC62061 标准 SIL3 的接触器组合。

主要优点：

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 bbbb 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
