The main contact rating at AC-3 (motor duty) hits 1000 operations per hour, which is standard for a general-purpose S0 contactor; AC-4 (inching/jogging) drops to 300 1/h because the arc stress on the contacts is heavier. Wire range: solid or stranded 1 to 10 mm², and it also accepts 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) for daisy-chaining. That covers most panel wiring up to 10 AWG. The arcing time is 10 ms, and the AC switching time is 4 to 16 ms — fast enough for standard motor starts, but if you're coordinating with a soft starter or VFD output, check the contactor's make/break timing against the drive's pre-charge circuit. That's the minimum air gap for arc flash and heat dissipation — tighter than some older designs, so a panel built for a different S0 contactor may need a quick check before dropping this one in. That helps when the panel layout is tight and the rail is at an odd angle.","metaTitle":"Siemens 3RT2024-1AC24 SIRIUS Power Contactor, S0, 24 VDC coi","metaDescription":"Siemens 3RT2024-1AC24 SIRIUS power contactor, size S0, 24 VDC coil, screw terminals, 45 mm wide, snap-on DIN rail.
