At 400 V, the contactor is rated 5.5 kW in AC-2 duty (slip-ring motors) and 12.5 A in AC-4 duty (reversing / inching / plugging). Those are the ratings that govern real motor-switching life — AC-4 especially, because every reversal cycle wears the contacts faster than a simple start/stop. ## Mounting and wiring — panel fit Side-by-side mounting is permitted with no derating gap. Main circuit terminals accept screw-type connections: 2×(0.5–1.5 mm²), 2×(0.75–2.5 mm²), or max 2×(0.75–4 mm²) solid/stranded. Auxiliary and control circuit terminals take 2×(1–2.5 mm²) or 2×(2.5–6 mm²), max 2×10 mm². AWG equivalents are 2×(16–12), 2×(14–10), or 1×8 for the mains, and 2×(20–16), 2×(18–14), or 1×12 for the auxiliaries. For Type 1 coordination (welding allowed but no fire hazard), the fuse can be gL/gG 63 A. The contactor carries IP20 protection on the front (touch-safe for panel installation) and IP00 at the terminals (requires enclosure protection downstream).","metaTitle":"Siemens 3RT1024-1AB00 SIRIUS Power Contactor, 3-pole, 24 V 5","metaDescription":"Siemens 3RT1024-1AB00 SIRIUS power contactor, 3-pole NO main contacts, 24 V 50 Hz coil, S0 frame, screw terminals, AC-2/AC-4 motor ratings, IP20 front, current lifecycle.
