What this selector switch does in a motor starter circuit
The 3RA9012-5BR43 is a 2-position selector switch with a spring return to the left position, carrying one normally-open (1NO) contact. It belongs to the Siemens GM-SET accessory family for the SIRIUS motor starter lineup. The cage clamp termination accepts solid or ferruled stranded wire without needing a screwdriver — push the conductor in and the clamp holds. Wires up clean in a packed DIN rail enclosure, no torque check needed.
