从进料到运动馈线的一致溶液
带有集成PE栏的3RA6的Sirius Infeed系统为
offered as a user-friendly possibility of feeding in summation
currents up to 100 A with a maximum conductor cross-section
of 70 mm² and connecting the motor cable directly without
其他中间终端。
Screw and spring-type terminals
The SIRIUS compact starters and the infeed system for 3RA6 are
available with screw and spring-type terminals.
工程系统配置器
一种free system configurator is available to reduce further the
amount of engineering work for selecting the required compact
starters and matching infeed.
Use of load feeders in conjunction with IE3/IE4 motors

3RA6 fuseless compact starters are available in five current
环境ranges. The 3RA61 and 3RA62 have two control voltage
ranges (AC/DC), and the 3RA64 and 3RA65 have one control
voltage range (DC):
