Dimensions are 172 mm high, 140 mm wide, and 170 mm deep — that depth matters when you're laying out a panel with limited enclosure clearance. The contactor is screw-fixed, not DIN-rail snap-on, so plan for drilled mounting holes (9 mm diameter, single hole per fixing point). Operating temperature range is -25 to +55 °C, storage from -55 to +80 °C. Mechanical life is typical 10,000,000 operations; switching frequencies vary by duty: AC-1 at 800 cycles/h, AC-3 at 750 cycles/h, AC-4 at 130 cycles/h. Main power circuit accepts stranded conductors from 25 to 120 mm². The auxiliary switch terminals handle solid wire: 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), or max 2x (0.75–4 mm²). Coil terminals are screw-type, same as the main terminals. Clearances: 10 mm upwards, 20 mm forwards, 10 mm downwards, 10 mm at the side — keep those for arcing and heat dissipation. Arcing time is 10–15 ms; coil pick-up and drop-out both run 80–90 ms (AC and DC).","metaTitle":"Siemens 3RT1056-6QP35 SIRIUS Power Contactor, Size S6, 200-2","metaDescription":"Siemens 3RT1056-6QP35 SIRIUS power contactor, size S6, 200-277V AC/DC coil, screw terminals, 170 mm depth.
