Screw-type terminals on the main circuit accept solid conductors up to 2x 2.5 mm² or stranded up to 2x 25 mm². The coil holds on a 24 VDC supply at 10 A, dropping out below 18 V. The S2 footprint — 75 mm wide, 112 mm tall, 115 mm deep — fits standard panel layouts with side-by-side mounting permitted for dense packing. AC-2 at 400 V: 18.5 kW. AC-4 at 400 V: 35 A. This is the plugging/reversing rating — the most severe duty class, where the contactor must interrupt locked-rotor current (typically 6–8x FLA). A 35 A AC-4 capability means it can handle a 7.5 kW motor in reversing service without accelerated contact wear. AC-1 maximum operating rate: 1,200 cycles/hour; AC-3: 1,000 cycles/hour; AC-4: 300 cycles/hour. RoHS compliance date is May 1, 2012, covering the EU RoHS exemption regime. The part carries the substance prohibitance marking per the manufacturer's declaration. ## Integration Notes Terminals: main circuit screw terminals accept 2x solid 0.25–2.5 mm² or 2x stranded 0.75–25 mm². The control circuit (coil) uses the same terminal type. Wire strip length per standard practice — no special tooling required. IP20 on the front (finger-safe when mounted in an enclosure); IP00 at the terminals (bare connection points — enclosure door must be interlocked or tool-accessible). Coil pickup time at AC: 7–20 ms; arcing time 10–15 ms. For timing-sensitive circuits (e.g., safety interlocks), account for the full dropout delay plus arc extinction when coordinating with upstream breakers.","metaTitle":"Siemens 3RT1035-3AP06 SIRIUS Power Contactor, 18.5 kW AC-2","metaDescription":"Siemens 3RT1035-3AP06 SIRIUS power contactor, S2 frame, 18.5 kW at 400 V AC-2, 35 A AC-4.
