Product details

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.

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.

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.

Frequently asked questions

What is the mounting method for 3RT2346-1AF00?

It mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715, with flexible orientation: +/-180° rotation and +/-22.5° tilt on vertical surfaces.
