The Siemens 3RT1024-1AB00-ZI41 is a 3-pole contactor in the SIRIUS family, size S0, with screw terminals. Its AC-3 rating of 5.5 kW at 400 V means it's sized for switching three-phase induction motors up to that load — typical for pumps, fans, and small conveyors on a 400 V line. The AC 24 V, 50 Hz coil lets you pull it in directly from a control transformer or a 24 VAC supply; keep in mind that at 50 Hz the hold-in power is lower than at 60 Hz, so if your site runs 60 Hz the coil impedance shifts and the pickup voltage may need checking against the actual supply.

Frequently asked questions
What is the closest pin-compatible alternative?
No official pin-compatible alternative is listed because this part is current production — there is no need for a substitute. If you need a different coil voltage or terminal style, the SIRIUS S0 family offers variants with DC coils or spring-cage terminals, but those are different order codes, not drop-in replacements.
What compliance documentation is available?
Standard Siemens documentation for this series includes a CE declaration of conformity and, depending on the variant, UL/CSA recognition. The specific certificates for this order code are available on request as part of the standard product documentation package.
