概述
Auxiliary switches
The auxiliary switches can be designed as positively driven
contacts in 3RH contactor relays or also as mirror contacts in the
case of 3RT power contactors.

用于安装的固态时间延迟辅助开关块
on 3RT2 contactors and 3RH2 contactor relays
请参阅第3/82页和3/100
3RA28固态时间延迟辅助开关
be mounted onto the contactor are designed for applications in
范围从24到240
V AC/DC（宽电压范围）。这俩
电气和机械连接是通过简单的快照进行的
ping on and locking.
Time-Delay辅助开关直接提供电源
通过接触器的线圈端子的两个插入式触点，
in parallel with A./A2.
A protection circuit (varistor) is integrated in each module.
A sealable cover is available to protect against careless
adjustment of the set times.
Note:
安装更多辅助切换到接触器不是
permitted.

所有3RT2接触器和3RH2接触器继电器都可以改装
with RC elements or varistors for damping opening surges in the
coil. Diodes or diode assemblies (comprising noise suppression
可以使用二极管和齐纳二极管短暂休息时间）。
浪涌电压抑制器插到前面啊f size S00
contactors. Space is provided for them next to a snap-on
auxiliary switch block.
可以插入变种，RC元素或二极管组件
进入S0至S3接触器的前面。
Coupling contactors are supplied either without overvoltage
阻尼或抑制二极管，静脉曲张或二极管
nected as standard, according to the version.
Note:
否接触的休息和延迟
NC contact are increased if the contactor coils are attenuated
针对电压峰（噪声抑制二极管6至10次；
二极管组装2至6次，变种+2至5 ms）。
