That rating means it handles the locked-rotor inrush and breaking of an induction motor up to that current without welding the main contacts. AC-3 at 480 V is the number that decides whether this contactor lives in your motor starter. It carries 52 A continuously and breaks the same current during a stop. The AC-3 electrical life at maximum rate is 800 operations per hour, which is fine for a conveyor or pump cycling at moderate speed; for high-speed jogging you'd derate. That gives you options in a crowded panel. The 55 mm width and 114 mm height fit the standard S2 footprint — same as other SIRIUS S2 contactors, so a panel laid out for a 3RT2028 or 3RT2037 will accept this one without re-drilling the DIN rail.","metaTitle":"Siemens SIRIUS 3RT2036-1AD00 Power Contactor, Size S2, 52 A","metaDescription":"Siemens SIRIUS 3RT2036-1AD00 Size S2 power contactor, 52 A at 480 V AC-3, screw terminals, DIN rail mount.

If your motor load exceeds 52 A at 480 V AC-3, that part steps up. For loads at or below 52 A, the 3RT2036-1AD00 is the correct fit and the more economical choice. Both share the same mounting footprint and terminal layout, so no panel rework is needed to swap between them."},{"question":"What are the key dimensions — depth, width, height?","answer":"Depth is 130 mm, width is 55 mm, height is 114 mm. These are the S2 frame dimensions common across the SIRIUS contactor family. The part mounts on 35 mm DIN rail with screw and snap-on fastening."},{"question":"Will the 3RT2036-1AD00 drop into a panel specified around the 3RT2037-1AF00-ZX95?","answer":"Yes, same S2 frame size and same DIN rail mounting method. The 55 mm width and 114 mm height are identical, so no re-drilling or re-spacing is needed. The terminal arrangement is also screw-type for both, so wiring changes are minimal — just verify the coil voltage matches your control circuit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT2036-1AD00","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/3RT2036-1AD00 when reusing this data.
