Rated for 1000 operating cycles per hour in AC-3 duty (motor switching), and 300 cycles/h in the heavier AC-4 duty (inching/plugging), this contactor handles frequent cycling without exceeding thermal limits. The auxiliary contact block supports a range of control voltages: 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, and 0.6 A at 440 V. These ratings cover typical PLC and relay interface levels, so the auxiliary contacts can drive pilot lights, contactor coils, or PLC inputs directly. Side clearance of 6 mm is required; vertical clearance of 10 mm upwards and downwards, and 10 mm forward, keeps airflow and arc-quenching space. Dimensions: 85 mm height, 45 mm width, 97 mm depth. Wire termination: main contacts accept solid or stranded wire from 1 to 10 mm²; auxiliary contacts accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²). All terminals are screw-type, requiring a screwdriver for termination — no spring-cage option on this variant. The storage limit exceeds the operating range, so the contactor can be warehoused in unconditioned spaces as long as it is not energized outside its rated ambient.","metaTitle":"Siemens SIRIUS 3RT2024-1AG20 Power Contactor, S0 Frame, 24 V","metaDescription":"Siemens SIRIUS 3RT2024-1AG20 power contactor, S0 frame, 24 VDC screw-type coil.
