The coil pulls in on 230-240 VAC, 50/60 Hz. It's a Size S2 frame with screw terminals — the standard footprint for panel builders wiring motor starters, pump controls, and conveyor drives up to that load. ## Lifecycle Reality — Phased Out This exact order code is flagged as a phased-out product. The official successor is the SIRIUS 3RT2 family. If you're replacing a failed unit on a live line, the 3RT2 is the drop-in path — same Size S2 footprint, same screw terminal layout, and the AC-3 current ratings carry over. For a BOM line that still specifies this 3RT1 code, we source it through independent surplus and last-time-buy channels against an RFQ; expect no factory support or warranty from Siemens. AC-3 40 A is the motor-switching rating — it handles starting inrush (typically 6–8x FLA) and breaks the load under running conditions. The 18.5 kW at 400 V figure is the three-phase motor it can switch; if your motor is 400 V and draws less than 40 A in AC-3, this contactor has headroom. The 230-240 VAC coil means it's direct-on-line from a control transformer or PLC relay output at that voltage — no DC conversion needed, but verify the coil pickup/dropout curve if your control voltage sags. Size S2 with screw terminals means it occupies the same DIN-rail footprint as other S2 contactors (roughly 55 mm wide) and accepts standard ring or fork lugs; no special crimp tool required.","metaTitle":"Siemens 3RT1035-1AP80-0KR0-ZX95 Power Contactor, AC-3 40 A,","metaDescription":"Siemens SIRIUS 3RT1 power contactor, AC-3 40 A / 18.5 kW at 400 V. 230-240 VAC coil, 3-pole, Size S2, screw terminals.
