The coil pulls in on 110–127 V AC; the contactor carries an integrated auxiliary switch block, so you get one less add-on to spec. Rated for AC-3 motor switching at up to 1,000 operating cycles per hour, with AC-4 (inching/plugging) duty capped at 130 ops/h — that 130 figure is the one to watch if your application does frequent reversals or jogging; exceeding it accelerates contact wear. The auxiliary contacts are rated 10 A at 24 V, 2 A at 48 V and 60 V, and 1 A at 110 V — choose your control voltage accordingly; the 110 V derating is steep enough that a 24 V control circuit gives you more headroom on the aux side. ## Integration notes — panel fit and wiring Main power terminals accept stranded 25–120 mm²; coil and auxiliary terminals take 2x 0.25–2.5 mm² solid or stranded. The spring-type coil terminals (no screw) mean the control wiring lands faster and stays secure under vibration — a detail worth noting if the panel sees pump or compressor rumble. That 20 mm forward clearance is the critical one — ensure the enclosure door or busbar shroud doesn't crowd the arc chute.","metaTitle":"Siemens 3RT1054-2AF36 SIRIUS Power Contactor, S6 Frame, 110-","metaDescription":"Siemens 3RT1054-2AF36 SIRIUS power contactor, size S6, 110-127 VAC coil, spring-type terminals.

The mounting footprint and main power terminal positions are the same S6 frame, so the mechanical swap is direct. The coil wiring method differs — spring clamp vs screw — so the control circuit termination needs a different tool (or no tool) but the same wire gauge range."},{"question":"What is the auxiliary contact rating at 24 V?","answer":"10 A at 24 V rated value.
