It is rated for motor switching at 7.5 kW at both 400 V and 690 V in AC-3 duty, and handles 12.5 A in AC-4 (reversing/inching) at 400 V. The S0 frame (45 mm wide, 85 mm tall, 91 mm deep) mounts on 35 mm DIN rail per EN 50022, with screw and snap-on fixing. ## Coil and auxiliary contact ratings The 24 VAC coil draws at 50 Hz 0.8 to 1.1 A, and at 60 Hz 0.85 to 1.1 A. The contactor carries one instantaneous auxiliary contact rated 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 0.3 A at 220 V (AC-12). Auxiliary contact ratings also cover 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — check the specific load voltage against the curve if switching at intermediate values. ## Short-circuit coordination and wiring Main circuit terminals accept solid/stranded 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²); auxiliary terminals accept 2x (1 to 2.5 mm²), 2x (2.5 to 6 mm²), max 2x 10 mm². AWG equivalents are 2x (16 to 12), 2x (14 to 10), 1x 8 for main contacts.","metaTitle":"Siemens 3RT1024-1AC20-ZX95 SIRIUS Power Contactor, 7.5 kW at","metaDescription":"Siemens SIRIUS 3RT1024-1AC20-ZX95 power contactor, S0 size, 24 VAC coil, 7.5 kW at 400 V and 690 V.
