Its envelope is 152 mm deep, 70 mm wide, and 140 mm high — the S3 footprint fits standard panel layouts with clearance requirements of 10 mm upwards, 10 mm downwards, 20 mm forwards, and 10 mm at the side. The mounting position is flexible: +/-180° rotation on a vertical surface, and can be tilted forward/backward by +/-22.5° on a vertical surface. ## Coil and Switching Duty The coil is rated 175-280 V AC, consuming 3.5 VA at both 50 Hz and 60 Hz, with an inrush current peak of 65 A and spring-type terminals for fast wiring. Operate times are 38-57 ms for both AC and DC, with an arcing time of 10-20 ms — these define the switching window for coordination with upstream protection. Maximum switching rates vary by duty: 900 ops/h at AC-1, 350 at AC-2, 850 at AC-3 and AC-3e, and 250 at AC-4 — the AC-3 rate is the one that governs motor starting duty in most conveyor and pump applications. ## Wiring and Contact Ratings Main contact wiring accepts solid conductors 2.5-16 mm² or stranded 6-70 mm²; auxiliary wiring uses 2x (0.5-2.5 mm²) solid or stranded — the spring terminals on the coil side and screw-type main terminals handle the full range. The auxiliary switch is present (yes), with rated values of 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, and 1 A at 110 V — these are the contact ratings for the built-in auxiliary, not the main poles. Main contact rating is listed as 10...2 (likely amperes, per S3 frame typical range), and mechanical life is 10,000,000 operations typical. ## Environmental and Lifecycle Operating temperature range is -25 to +60 °C; storage range is -55 to +80 °C — the wide storage window suits spares held in unheated warehouses.","metaTitle":"Siemens 3RT2046-3NP30 SIRIUS Power Contactor, S3","metaDescription":"Siemens 3RT2046-3NP30 SIRIUS power contactor, size S3, 175-280 V AC coil, spring-type terminals.
