概述
Auxiliary switches
See from page 4/40 onwards
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.

辅助开关块
请最多可以连接八个辅助联系人
note the following:
•
Of these eight auxiliary contacts, there must be no more than
四个NC触点。
•
Ensure the symmetry of laterally mounted auxiliary switch

弹簧终端(也)
All 3RT13 contactors can be retrofitted with RC elements or
varistors for damping opening surges in the coil. Diodes or
二极管组件（包括噪声抑制二极管和
可以使用Zener二极管短时间）。
使用这些接触器，变种器，RC元素和二极管
可以直接在线圈端子上插入组件，
在顶部或下面。
The plug-in direction of the diodes and diode assemblies is
determined by a coding device.
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）。
PLC控制的耦合链接

3RH2924-1GP11耦合链接具有集成激增
suppressor (varistor) for the contactor coil being switched and is
mounted onto the size S0 contactor coil via a coil connection
模块。
Sealable covers
请参阅第4/46页
When contactors and contactor relays are used in safety-related
申请，必须确保无法操作
the contactors manually.
For SIRIUS contactors there are sealable covers available for
this purpose as accessories; these prevent accidental manual
operation. These are transparent molded-plastic caps with a
可以密封接触器的支架。
