The 3RT2018-1AN61: Mounting is screw-and-snap onto a 35 mm DIN rail per DIN EN 60715. The coil terminals are screw-type, accepting 0.5–4 mm² solid or stranded wire (2x per side for certain combinations). Overall footprint is 45 mm wide × 58 mm tall × 73 mm deep, with clearances: 10 mm top/bottom, 6 mm sides, and 10 mm front/back for arc quenching. Sourcing this one through our desk: genuine is genuine. No regional lock on the part itself — same SIRIUS contactor, different origin passport. We're quoting to order against an RFQ; compliance documentation (per the brand's standard) accompanies each shipment. No surprises, just the part your BOM line expects.
