The Siemens 3RT1945-6A is a replacement contact-piece kit for a 3-pole contactor in frame size S3, rated AC-3 at 37 kW. It includes three movable and six fixed main contacts plus mounting hardware. This is a phased-out product; the official successor contactor family is the SIRIUS 3RT2.
The official successor contactor family is the SIRIUS 3RT2. However, the 3RT2 uses different contact-piece part numbers, so there is no direct drop-in replacement for this exact kit. The 3RT1945-6A is sourced as a new-old-stock or surplus item.
This part is sourced to order against an RFQ through surplus and broker channels. No stock or lead-time figures are available; submit an RFQ for a sourcing quote.
