Siemens SIRIUS 3RT2346-1AP00 — Size S3 Contactor with Integrated Auxiliary Switch
It snaps onto a 35 mm DIN rail per DIN EN 60715 and can be screw-mounted as well, with mounting positions allowing ±180° rotation on a vertical surface and ±22.5° tilt forward/backward — helpful when fitting into tight enclosures. The integrated auxiliary switch (1 NO + 1 NC configuration, with the main contacts configurable as 10 N/O to 2 N/C) gives this contactor a built-in feedback or interlock path without a separate add-on block. Rated for 10 A at 24 V AC, 6 A at 230 V AC, and 3 A at 400 V AC, the auxiliary contacts cover typical PLC-level signalling and small relay loads.
Mounting and Wiring — Panel Integration Notes
Dimensions: 96 mm wide, 140 mm high, 152 mm deep. Main contact wiring accepts stranded conductors from 6 to 70 mm² — sized for motor feeders up to roughly 30–40 kW depending on duty. Coil terminals are screw-type; the auxiliary switch terminals accept solid or stranded wire: 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²).
