Product details

The Siemens SIRIUS 3RT1024-3AN20-1AA0 is a size S0 power contactor rated for motor switching up to 7.5 kW at 690 V AC-3 (or 7.5 kW at 500 V). In AC-2 duty at 400 V it handles 5.5 kW, and in AC-4 (reversing/inching) it carries 12.5 A at 400 V.

Front protection is IP20; the terminal area is IP00 — keep live parts behind a panel door or cover.

The integrated auxiliary contact (1 NO + 0 NC) is rated 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — sufficient for signaling to a PLC or pilot lamp. At 220 V DC the rating drops to 0.3 A; verify DC load break capability for your specific inductive load.

Frequently asked questions

Will 3RT1024-3AN20-1AA0 drop into a panel specified around 3RT1023-1AL20 without rewiring?

Both are S0 size on 35 mm DIN rail, so the mechanical footprint is the same. However, the 3RT1024-3AN20-1AA0 has a different auxiliary contact arrangement (1 NO, 0 NC) and higher main current rating — verify that the existing wiring and fuse coordination (Type 2 requires 25 A gL/gG) match the new contactor's ratings before swapping.

Where can I buy 3RT1024-3AN20-1AA0?
