Rated for AC-2 duty at 5.5 kW and AC-4 at 12.5 A, both at 400 V, this contactor handles squirrel-cage motor starting and plugging/reversing loads. The screw-type main terminals accept up to 2x 10 mm² stranded or 1x 8 AWG, making it straightforward to land in a mixed-gauge panel. ## Switching Ratings and Coordination The DC switching matrix covers 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — useful for interposing relays or small DC motor brakes. AC-12 resistive switching is rated to 10 A maximum. For motor protection, Type 2 coordination requires a 25 A gL/gG fuse; Type 1 allows up to 63 A. The 400 V AC-2 power rating (5.5 kW) matches a typical 7.5 hp motor at 400 V three-phase. Side-by-side mounting is permitted with zero spacing, saving DIN rail space; 6 mm clearance is required at the sides for airflow if derating is a concern.","metaTitle":"Siemens 3RT1024-1AR60 SIRIUS Power Contactor, 24 VDC Coil, S","metaDescription":"Siemens 3RT1024-1AR60 SIRIUS power contactor, 24 VDC coil, S0 frame, 45 mm wide, screw terminals, IP20 front, rated for AC-2 5.5 kW / AC-4 12.5 A at 400 V.
