Sourced through independent distribution; availability and volume pricing confirmed at RFQ against your line-item quantity. ## Motor-duty rating — 96 A at 480 V AC-3 The headline motor-switching rating is 96 A at 480 V — that's the AC-3 current for squirrel-cage motor starting. In a 480 V panel, this contactor handles motors up to about 50 hp (typical rule-of-thumb: 1 hp ≈ 1.8 A at 480 V three-phase). Switching frequency limits vary by duty: 850 operations/hour in AC-3, 350/h in AC-2, and 250/h in AC-4. For high-cycle applications like conveyor indexing, stay within the AC-3 ceiling; AC-4 plugging or inching cuts the rate by more than half. ## Mounting and clearance — DIN rail plus air gaps Mounts via screw and snap-on onto 35 mm standard rail per DIN EN 60715. The contactor body is 70 mm wide, 140 mm tall, 152 mm deep. Minimum clearances: 10 mm upwards, 20 mm forwards, 10 mm sideways, 10 mm downwards. These are the free-air gaps for arc dissipation and cooling — crowding them reduces the switching life. Mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward. That flexibility helps when the rail is in a tight enclosure corner. ## Wiring — screw terminals, dual conductor capability Main circuit terminals accept solid 2.5–16 mm² or stranded 6–70 mm². The coil terminals are screw-type and accept 2x (0.5–1.5 mm²) or 2x (0.75–2.5 mm²) solid or stranded. Dual-conductor entry on the coil terminals means you can daisy-chain control voltage without an extra terminal block — saves a rail position. ## Environmental limits — storage and operation Operates from -25 to +60 °C ambient; storage range is -55 to +80 °C. The -25 °C floor matters for unheated plant areas in cold climates — the contactor's mechanical life (10 million operations typical,) assumes the lubricant stays within this band.","metaTitle":"Siemens 3RT2046-1AT60 SIRIUS Contactor, 96 A at 480 V","metaDescription":"Siemens 3RT2046-1AT60 SIRIUS power contactor, 96 A at 480 V AC-3, Size S3, screw and snap-on DIN rail mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Contactors"],"specifications":{"Depth":"152 mm","Solid":"2.5 ... 16 mm²","Width":"70 mm","at AC":"10 ... 21 ms","title":"3RT2046-1AT60","Height":"140 mm","Upwards":"10 mm","Forwards":"20 mm","Stranded":"6 ... 70 mm²","at 60 Hz":"0.4","Downwards":"10 mm","Arcing Time":"10 ... 20 ms","At The Side":"10 mm","description":"power contactor, AC-3e/AC-3, 95 A, 45 kW / 400 V, 3-pole, 600 V AC, 60 Hz, auxiliary contacts: 1 NO + 1 NC, screw terminal, size: S3","During Storage":"-55 ... +80 °C","Of Magnet Coil":"Screw-type terminals","at AC-1 maximum":"900 1/h","at AC-2 maximum":"350 1/h","at AC-3 maximum":"850 1/h","at AC-4 maximum":"250 1/h","lifecycle_stage":"current","Auxiliary Switch":"Yes","During Operation":"-25 ... +60 °C","Fastening Method":"screw and snap-on mounting onto 35 mm standard mounting rail according to DIN EN 60715","at AC-3e maximum":"850 1/h","For Main Contacts":"10 ... 2","Mounting Position":"+/-180° rotation possible on vertical mounting surface;
