The AC-2 and AC-3 motor-switching ratings are given as power: 5.5 kW at 400 V for AC-2, and 7.5 kW at both 500 V and 690 V. That 7.5 kW at 690 V tells you this contactor can handle a 690 V motor load — useful in mining or marine installations where 690 V distribution is common. The coil holds at 24 V rated value drawing 10 A (likely inrush), with lower holding currents at higher control voltages: 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V. The rated frequency is 50 Hz with a tolerance factor of 0.8 to 1.1 — so it can run on a 50 Hz supply with some voltage variation but is not rated for 60 Hz operation. Width is 45 mm, height 85 mm, depth 140 mm — the S0 frame is a compact footprint that fits alongside other SIRIUS components on the rail. Main-circuit terminals are screw-type, accepting 2x (0.25…2.5 mm²) solid or 2x (1…2.5 mm²) stranded, up to 2x 10 mm². AWG equivalents: 2x (16…12) or 2x (14…10) or 1x 8. The auxiliary contact block has 2 instantaneous contacts. Maximum altitude is 2000 m without derating.","metaTitle":"Siemens 3RT1024-3AP04-1AA0 SIRIUS Power Contactor, 3 NO, S0,","metaDescription":"Siemens SIRIUS 3RT1024-3AP04-1AA0 power contactor, S0 frame, 3 NO main contacts, screw terminals, IP20 front, 45 mm wide.
