The 230 V AC coil at 50/60 Hz matches standard control-voltage transformers in most European and Asian panels. Size S2 snaps onto a standard DIN rail (35 mm) and occupies about 114 x 55 x 130 mm of enclosure space. The 3-pole power circuit lands on the top and bottom screw terminals; the coil and auxiliary contacts are on the front face, clearly marked. If you're replacing an older SIRIUS 3RT or a 3TF contactor, the footprint and terminal layout are the same — no re-drilling the backplate. Multi-unit packaging means this order code ships six contactors in one carton, so for a panel with multiple motor starters you get consistent parts in one bin.","metaTitle":"Siemens 3RT2035-1AL20-Z W97 power contactor, 41 A, 18.5 kW","metaDescription":"Siemens SIRIUS 3RT2035-1AL20-Z W97 power contactor, AC-3e/AC-3 rated 41 A, 18.5 kW at 400 V, 3-pole, 230 V AC coil.

The 41 A rating at 400 V translates to 18.5 kW for a standard three-phase motor. If your motor draws more than 41 A during starting or running, step up to the next SIRIUS size."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT2035-1AL20-Z-W97","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RT2035-1AL20-Z-W97 when reusing this data.
