Screw-type terminals on the main circuit accept solid conductors from 2x (0.25... 2.5 mm²) up to stranded 2x (10... 50 mm²). The contactor snaps onto 35 mm or 75 mm DIN rail and measures 70 mm wide by 176 mm high by 152 mm deep — a standard panel footprint for this frame class. The front terminals carry IP20 protection, which is sufficient for finger-safe access inside a closed panel; the terminal body itself is IP00, so it expects enclosure protection from the cabinet. ## Switching performance and thermal limits Mechanical endurance is rated at 10 million operations typical, but the practical switching rate depends on the duty cycle: AC-1 (resistive) allows up to 900 cycles per hour, AC-3 (motor start/run) 850 per hour, AC-4 (plugging/inching) drops to 250 per hour. Arcing time runs 10 to 15 ms, with DC arc extinction taking 14 to 20 ms. The contactor handles 50 and 60 Hz supply with a voltage tolerance of 0.8 to 1.1 times rated. For side-by-side mounting, derate the thermal current accordingly — the 37 W power dissipation at 1000 V gives a rough heat load to factor into panel ventilation. The integrated auxiliary contacts are rated for 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, and 3 A at 400 V. These cover typical PLC input and relay coil loads; verify the inrush of the specific load against the make/break capacity at your control voltage.","metaTitle":"Siemens 3RT1046-3XF00-0GA0 SIRIUS Power Contactor, Size S3,","metaDescription":"Siemens 3RT1046-3XF00-0GA0 SIRIUS power contactor, Size S3, 45 kW at 400 V AC-2, screw terminals, IP20 front, current lifecycle.
