The auxiliary contact block carries 10 A at 24 V, derating to 3 A at 400 V and 0.6 A at 440 V, so it handles pilot-duty loads (PLC inputs, small relays) across a wide voltage range. Switching frequency tops out at 1000 operations per hour for AC-1 resistive loads, 750 ops/h for AC-3 motor switching, and 250 ops/h for AC-4 plugging/inching duty. That means it cycles a motor start every 4.8 seconds at full AC-3 rate — fine for a conveyor or pump station, but not for a high-speed pick-and-place cell. Main contacts accept 1–10 mm² solid or stranded; auxiliary contacts accept 2×(0.5–1.5 mm²) or 2×(0.75–2.5 mm²). Coil terminals are screw-type.","metaTitle":"Siemens 3RT2027-1AR60 SIRIUS Power Contactor, S0 Frame, 24 V","metaDescription":"Siemens 3RT2027-1AR60 SIRIUS power contactor, size S0, 24 VDC coil, screw terminals, snap-on DIN rail.
