AC-3 (IEC 60947-4-1) covers starting and disconnecting squirrel-cage motors under load, so this is the figure that decides whether the contactor holds in on a pump, fan, or compressor start. It carries a 20 hp rating at 230 V, and the auxiliary contact block is present (10 A at 24 V, 2 A at 48 V, 1 A at 110 V, 0.3 A at 220 V). That matters when you are fitting it into a crowded panel — you are not locked into one orientation. Main circuit wiring accepts solid conductors 2.5 to 16 mm² and stranded 6 to 70 mm². The magnet coil connection uses spring-type terminals, which speeds up wiring and avoids re-torquing on a maintenance visit. Depth is 152 mm, width 70 mm, height 140 mm — the S3 footprint is compact for the 96 A rating. ## Switching frequency and thermal limits Rated switching frequency varies by duty: 900 cycles/hour in AC-1 (resistive), 850 in AC-3 (motor start/run), 350 in AC-2 (slip-ring motors), and 250 in AC-4 (plugging/inching). The AC-3e maximum is also 850 cycles/hour. For a conveyor line cycling every 30 seconds, that is comfortably within the 850/h ceiling.","metaTitle":"Siemens 3RT2046-3AF00 SIRIUS Power Contactor, 96 A AC-3, S3","metaDescription":"Siemens 3RT2046-3AF00 SIRIUS power contactor, S3 size, 96 A rated operational current at 480 V AC-3.

It will not drop into a panel wired for the S3 3RT2046-3AF00 without rewiring — the S3 has larger main terminals (70 mm² stranded vs. the S0's smaller capacity) and a different mounting footprint. Use the 3RT2046-3AF00 as the BOM line specifies."},{"question":"What is the depth of the 3RT2046-3AF00?","answer":"152 mm."},{"question":"What solid conductor range does the main circuit accept?","answer":"2.5 to 16 mm² solid."},{"question":"Will the 3RT2046-3AF00 drop into a panel specified around the 3RT2027-1AF00 without rewiring?","answer":"No. The S3 frame (3RT2046) is physically larger than the S0 frame (3RT2027) — different terminal sizes and mounting hole pattern. The 3RT2046-3AF00 accepts stranded conductors up to 70 mm², while the S0 frame typically handles smaller wire. You would need to re-terminate and possibly re-drill the mounting rail."},{"question":"What compliance documentation does Siemens provide for this contactor?","answer":"The evidence does not list specific certifications (UL, CSA, CE, RoHS, REACH) for this order code.
