The AC-1 maximum switching frequency of 1 000 1/h means this contactor can handle resistive loads at that rate without overheating the coil or contacts. For AC-4 duty (switching motor loads during starting/plugging), the maximum drops to 300 1/h — a real constraint if your application cycles a motor under load more than five times per minute. The mechanical life of 10 000 000 operations is typical for this class, so the limiting factor in service will be electrical wear from the specific load type, not the mechanism. The coil draws 6 A at 24 V rated value, dropping to 2 A at 48 V and 0.3 A at 220 V — these are the holding currents, not inrush. The spring-type terminals accept solid or stranded wire from 1 to 10 mm², and dual 0.5 to 2.5 mm² for the coil circuit.","metaTitle":"Siemens 3RT2024-2AG24 SIRIUS Power Contactor, Size S0, 24 VD","metaDescription":"Siemens SIRIUS 3RT2024-2AG24 power contactor, Size S0, 24 VDC coil, spring-type terminals, 45 mm wide, current production.
