Side-by-side mounting allowed, so you can pack a row of these on a gland plate without derating for spacing. Dimensions: 148 mm high, 70 mm wide, 139 mm deep — that 70 mm width is the critical fill factor on a standard DIN rail. ## Electrical & Coordination AC-3e switching maxes at 800 operations per hour; AC-4 drops to 250 ops/h — the heavier the load, the slower the cycle. For type 1 coordination, Siemens calls for a 200 A gL/gG NH fuse (3NA). That's the selectivity gate for the panel designer: if your upstream breaker is smaller, the coordination table shifts. ## Control & Auxiliary Coil holds at 0.27 W DC, pulls 0.68 W DC during pickup — low enough for a PLC output to drive directly. Auxiliary contacts rated for PLC-level switching (17 V, 5 mA), so no dry-contact reliability worry on low-voltage digital inputs. Accepts 2x (0.5–1.5 mm²) or 2x (0.75–2.5 mm²) solid/stranded with ferrules. Degree of pollution 3 means it's fine in a typical industrial panel without conformal coating.","metaTitle":"Siemens 3RT7046-1AH00 SIRIUS Contactor, 3-Pole, AC-3 690 V,","metaDescription":"Siemens 3RT7046-1AH00 SIRIUS S3 contactor, 3 NO main contacts, AC-3 rated 690 V, screw terminals, IP20 front.
