At 690 V the AC-3 rating drops to 10 kW, which is typical for the voltage derating on this frame size. The auxiliary contact block is rated for 10 A at 24 V, 6 A at 230 V, and 0.3 A at 220 V DC — these are the figures for the control circuit, not the main poles. The terminal area is rated IP00 (no protection), so it must be inside an enclosure. The S2 frame is 55 mm wide and 112 mm tall, with a depth of 115 mm — that's the full body depth including the arc chute. Main circuit terminals are screw-type, accepting 2x (0.75...16 mm²) solid or stranded, or 2x (0.25...2.5 mm²) solid for the control circuit. The stranded range goes up to 25 mm² on the main terminals.","metaTitle":"Siemens 3RT1034-3AV00 SIRIUS Power Contactor, S2 Size, 55 mm","metaDescription":"Siemens 3RT1034-3AV00 SIRIUS power contactor, S2 size, 55 mm wide, rated 18.5 kW at 400 V AC-3.
