Product details

The Siemens SIRIUS 3RT2446-1AD00 is a size S3 contactor with an AC coil, screw-type terminals, and a rated operational current of 10 A at 24 V AC, 6 A at 230 V AC, and 3 A at 400 V AC — covering the common control and light-load switching range for motor starters and resistive loads in a 400 V three-phase panel.

The 70 mm width and 152 mm depth fit standard S3 contactor slots in a SIRIUS modular starter assembly. Side-by-side mounting is supported with a 10 mm clearance to adjacent devices on each side, 10 mm upwards and downwards, and 20 mm forward.

Main power terminals accept stranded wire from 6 mm² up to 70 mm² — heavy enough for the full rated current without piggyback lugs. Auxiliary terminals accept 2x (0.5–1.5 mm²) solid or 2x (0.75–2.5 mm²) stranded, with screw-type terminations on the magnet coil.

Frequently asked questions

Where can I buy 3RT2446-1AD00 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

What is 3RT2446-1AD00's listed depth (152 mm) on this component line?

The listed depth is 152 mm.

What is 3RT2446-1AD00's listed solid (2x (0.5... 1.5 mm²), 2x (0.75... 2.5 mm²)) on this component line?

The auxiliary terminals accept 2x (0.5–1.5 mm²) solid or 2x (0.75–2.5 mm²) stranded wire.

Will 3RT2446-1AD00 drop into a panel that was specified around 3RT2535-1AD00 without rewiring?

Both are SIRIUS S3 contactors with the same 70 mm width and 152 mm depth, so the mechanical footprint and DIN-rail mounting are identical. However, the 3RT2535-1AD00 has different coil voltage and switching ratings — verify the coil voltage matches your control circuit before swapping.

What compliance documentation does this brand provide for 3RT2446-1AD00 (RoHS, REACH, UL, IEC)?

The evidence does not list specific compliance documentation for this part. For RoHS, REACH, UL, or IEC declarations, request them with your RFQ.
