Product Overview

The 3RA6120-1BB32 is a Siemens SIRIUS Compact load-feeder direct-on-line (DOL) starter, part of the 3RA61 family. It enables direct switching of three-phase motors up to 690 V with a control voltage of 24 V AC/DC (50-60 Hz) and a rated current adjustment range of 0.32 to 1.25 A. Installed via screw-terminal connections for both main and auxiliary circuits, it finds use in standard motor control schemes for conveyor systems, pumps, fans, compressors, and other industrial motor applications.

Best Suited For

  • Starting small to medium three-phase motors
  • Integration into control panels with compact footprint
  • Applications requiring low voltage control (24 V AC/DC)
  • Installation in non-harsh environments (IP20 rated)
  • Replacement in existing SIRIUS 3RA61 starter arrangements
