What this kit actually is
The 3RA9011-5AW23 is a kit for the BESEL DMC 60T Siemens-STEUERUNG — it's not a standalone motor starter but a specific accessory bundle intended for that control unit. It sits within the Siemens Motor Starters category, meaning it's part of the motor control ecosystem, likely a pre-assembled wiring or mounting kit for a particular enclosure or drive package.
