The Siemens 3RT1935-6A is a replacement contact set for the SIRIUS S2 contactor frame — three movable and six fixed main contacts with mounting hardware, all 3 NO poles. It's rated AC-3 at 18.5 kW, which means it's specced for switching three-phase induction motors up to that power under full-load starting conditions. The description flags it as a phased-out product; the official successor contactor is the SIRIUS 3RT2 series.
Lifecycle and sourcing reality
