The Siemens 3RT1023-1AP80-0KR0-ZW97 is a Size S0 power contactor from the SIRIUS 3RT1 series, rated for AC-3 duty at 9 A and 4 kW at 400 V. The AC-3 rating means it is specified for starting and stopping squirrel-cage induction motors under load — the standard motor-switching category per IEC 60947-4-1. The 9 A AC-3 figure governs real motor sizing, not the higher AC-1 resistive rating.
