Siemens 3RA6400-1AB43 SIRIUS Compact Direct-On-Line Starter
The Siemens 3RA6400-1AB43 is a SIRIUS compact starter designed for direct-on-line (DOL) motor starting with IO-Link communication. This phase-out type operates at 690V with a 24V DC coil and has an adjustable current range of 0.1 to 0.4A, featuring an IP20 protection rating. The main circuit connects via plug-in, without terminals, and the control circuit uses screw terminals.
This starter is intended for applications requiring direct starting of small three-phase motors and integration with IO-Link systems for diagnostics and control. It is part of the SIRIUS 3RA64 series, offering compact size and integrated functionality. Note that this is a phase-out type, with alternatives like 3RK1308 or 3RA8 recommended for new designs requiring a controller like the ET 200SP.
