Siemens 3RK1304-5KS40-4AA0 is the SIMATIC ET 200pro DSe ST standard direct motor starter. It uses electromechanical switching with electronic overload protection. The adjustable current range matches the specified small-motor duty. This order configuration does not include a motor brake output. Its protected housing supports decentralized installation within the ET 200pro system.
The 3RK1304-5KS40-4AA0 switches a motor feeder directly rather than reversing its direction. Commands and status are integrated through the station backplane. The overload setting must be matched to the connected motor. The connector arrangement and the required power distribution should be checked before replacement. This decentralized starter is selected as part of the complete ET 200pro motor-control assembly.
Switch a suitable motor feeder using the standard electromechanical direct-starter arrangement.
Set the protection response to the connected motor's required operating current.
Exchange starter commands and status through the ET 200pro station and its supported network interface.
No. This is a direct starter; a reversing-starter configuration is different.
No. This order variant is supplied without a motor brake output.
Set it from the actual motor rating and application requirements within the supported adjustment range.
Communication is through the ET 200pro backplane and the station's interface arrangement.
No. Match the starter type, protection range, connectors and brake-output requirement as well.
Verify motor wiring, protective settings, supply connections and the station configuration before test operation.
