Power Contactors for Switching Motors
SIRIUS 3RT12 and 3TF6 vacuum contactors
3
1）
For ambient temperatures > 55 °C, only 3TF6.33-.Q..-Z A02 contactors
（=无主要电流路径电路的连接）可以使用。
然后，这些接触器也可能脱落：
- AC-1:
I
e
= 782 A，644操作周期/h;
-AC-3：操作范围0.85至1.05 x
U
s
, 460 operating cycles/h,
mech. endurance 5 million operating cycles, lateral clearance 10 mm.
2）
For 3TF6.-.C.. the following applies:
-
IP00没有覆盖(连杆directly from the front)
-
IP00带有导体进入的盖子
-
IP20 on the front plate with cover.
3）
For 3TF6.-.Q../-.D.. the following applies:
-
IP00 without box terminal (the connecting bar, series resistor and the
3TC44反向接触器直接从前面到达）
-
IP00 with box terminal (the series resistor and the 3TC44 reversing
contactor are reached directly).

Permissible mounting position
接触器设计用于垂直操作
安装表面。
• To easily replace the laterally mounted auxiliary
switches it is recommended to maintain a minimum
distance of 30 mm between the contactors.
No
是的
•如果以90°角安装（电流路径是水平的
彼此高），开关频率为
reduced by 80 % compared with the normal values.
