The contactor is rated for 1 000 operating cycles per hour at AC-1 (resistive), AC-2 (slip-ring motor), AC-3 (squirrel-cage motor), and AC-3e (enhanced AC-3) loads, and 300 cycles per hour at AC-4 (plugging/inching) duty. The 1 000 cycles/h rate covers most conveyor, pump, and fan applications; the lower AC-4 rate reflects the higher thermal stress of frequent reversing or inching. Mechanical endurance is listed at 10 000 000 operating cycles typical, which aligns with the SIRIUS family's design for long service intervals in continuous-process lines. Arcing time is stated as 10 ms at AC, which is a fixed value rather than a range — expect consistent arc extinction across the rated switching frequency. Main contacts accept solid or stranded wire from 1 to 10 mm²; auxiliary contacts (if present) accept 2x (0.5 to 2.5 mm²). These minimums govern panel layout — a 45 mm wide device needs 10 mm breathing space above and below, plus 6 mm lateral gap, to maintain rated creepage and clearance. For a BOM line requiring this exact order code, the part is specifiable and traceable — the SIRIUS series carries full compliance documentation including CE, UL, and CSA certifications. The spring-terminal variant (2AN24) is the coil-termination choice; the screw-terminal variant (2AG24) is a direct footprint substitute if panel wiring practices differ.","metaTitle":"Siemens 3RT2024-2AN24 SIRIUS Power Contactor, Size S0, 24 VD","metaDescription":"Siemens 3RT2024-2AN24 SIRIUS power contactor, Size S0, spring-type terminals, 24 VDC coil.
