That AC-2 rating covers wound-rotor motors and slip-ring applications where the load current stays fairly steady during make and break; The AC-12 maximum operating current of 10 A tells you the auxiliary circuit capacity for resistive loads like control transformers or indicator lamps. The S0 frame keeps the width to 45 mm — three contactors fit a 135 mm DIN section, which matters when you're packing multiple motor starts into a standard 600 mm enclosure. Termination is screw-type on the main circuit, accepting 2x (0.5 to 1.5 mm²) solid, 2x (0.75 to 2.5 mm²) stranded, or up to 2x 4 mm² max. The auxiliary contact block (2 N/O instantaneous) shares the same terminal family — no mixed tooling needed on the wireman's bench. Type 1 coordination requires a 63 A gL/gG fuse upstream; Type 2 coordination (the stricter one that keeps the contactor usable after a fault) needs a 25 A gL/gG fuse. That 25 A limit is the one to spec into the BOM if the panel must survive a short circuit without replacing the contactor — common for production lines where downtime for parts swap costs more than the fuse. ## Environmental limits","metaTitle":"Siemens 3RT1024-1AR64 SIRIUS Power Contactor, S0, 7.5 kW at","metaDescription":"Siemens 3RT1024-1AR64 SIRIUS power contactor, S0 frame, 7.5 kW at 400 V AC-2.
