SIRIUS S3 contactor — 24 V AC coil, screw terminals
The Siemens SIRIUS 3RT2346-1AF00 is a size S3 contactor with a 24 V AC magnet coil and screw-type terminals, designed for screw and snap-on mounting onto 35 mm DIN rail per DIN EN 60715. Its auxiliary switch is rated for 10 A at 24 V, 6 A at 60 V, and 6 A at 230 V, covering typical control-circuit voltages across global panels. Mechanical endurance listed at 10,000,000 operating cycles.
Mounting and integration
Mounts on 35 mm DIN rail per DIN EN 60715 via screw and snap-on fastening. The mounting position allows +/-180° rotation on a vertical surface and can be tilted forward/backward by +/-22.5° — useful for tight enclosures where standard orientation won't fit.
Wiring and conductor ratings
Main circuit accepts stranded conductors from 6 to 70 mm². Auxiliary/control wiring accepts solid or stranded: 2x (0.5 to 1.5 mm²) and 2x (0.75 to 2.5 mm²) — typical for panel-building with standard ferrule sizes.
Environmental and lifecycle
Rated for operation from -25 to +60 °C and storage from -55 to +80 °C, covering most indoor industrial environments without derating concerns at typical control-panel ambient temperatures.
Switching performance
Arcing time spans 10 to 20 ms at AC and 10 to 21 ms at DC, with shock withstand ratings of 10.6 g at 5 ms and 6.3 g at 10 ms — relevant for applications near heavy machinery or frequent start-stop cycles.
