The coil is 110 VAC 50/60 Hz. The S2 footprint is 75 mm wide, 112 mm tall, 130 mm deep. Side-by-side mounting is supported with no derating gap required. Front face is IP20; the terminal area is IP00 — plan for finger-safe covers if the contactor sits near the panel door. ## Ratings and Duty Cycles AC-3 switching rate maxes at 1 000 operations per hour; AC-4 (plugging/reversing) at 300 per hour. Mechanical life is 10 million cycles typical. Pollution degree 3 suits industrial environments. Built-in auxiliary contacts handle 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V. Pick-up voltage is 0.8 x nominal; drop-out is 1.1 x nominal.","metaTitle":"Siemens 3RT1035-3BF46 SIRIUS Power Contactor, S2, 110 VAC Co","metaDescription":"Siemens SIRIUS 3RT1035-3BF46 power contactor, size S2, 110 VAC coil, screw terminals, 22 kW at 500 V AC-3.
