3RH21221BP40(3RH21221BP40)

西门子SIEMENS 3RH系列SIRIUS中间继电器

适合于各种应用需求的中间继电器

西门子提供多种国产和进口中间继电器，用于控制回路信号指示、互锁功能等，并可满足不同层次的使用需求。

中间继电器用于控制回路，用于信号指示、互锁功能等。3RH2/3RH1 中间继电器标识符合相关标准，节约时间和成本。3RH2/3RH1 中间

继电器设计与 S00 规格接触器相同，可以通用相同的附件。

中间继电器可用于交流或直流操作，使用螺钉、弹簧或环形接线端子。本体包括 4 个触点，通过加装辅助触头座可扩展至 8 个触点。

新一代 SIRIUS（进口）3RH2 中间继电器

概述

3RH2 中间继电器的设计符合 IEC 60947 和 EN 60947。

3RH2 中间继电器可提供螺钉、弹簧式或环形接线端子，可使用交流或直流操作。

3RH2 中间继电器适用于任何气候条件，并具有符合 EN 50274的“指触防护”功能。

触点可靠性

触点在低电压及低电流的情况下，具有极高的可靠性，满足固态电路使用要求，17 V 电压下**小接通电流 1 mA。

浪涌抑制

阻容吸收（RC）、压敏电阻、二极管以及二极管组合（二极管与齐纳二极管组合）可以插接在中间继电器前面板上，用于抑制操作线圈时产生的浪涌。

注意：

使用浪涌抑制器抑制线圈过电压，会造成接触器常开触点 NO 分断延时以及常闭触点 NC 接通延时（抑制二极管将增加延时 6 到 10 倍，二极管组合将增加延时 2 到 6 倍，压敏电阻将增加延时 2 到 5 ms）。
