At 690 V AC-3, it handles 11.4 kW. Its dimensions are 55 mm wide, 112 mm high, and 164 mm deep, occupying a single modular slot. This is the rating that governs contact life under heavy switching — not the AC-3 figure. The AC-1 maximum operating rate of 1000 cycles per hour applies to resistive loads; AC-4 drops to 300 cycles per hour due to arc erosion. The auxiliary contact ratings cover a wide control voltage range: 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V. The 24 V rating is the one to check for PLC-driven circuits — it confirms the contacts can handle typical 24 VDC solenoid loads without derating. This is standard for open panel mounting but requires the IP20 front cover for operator safety. Main circuit terminals are screw-type, accepting 2x (0.75 to 25 mm²) stranded or 2x (0.25 to 2.5 mm²) solid. The 16 mm² minimum at 40 °C sets the smallest wire size for full rated current — use 16 mm² or larger for the power circuit to avoid terminal overheating. The IP00 terminal rating means the wiring area is not touch-safe — plan for finger-duct covers or shrouded terminals in the panel layout.","metaTitle":"Siemens 3RT1036-3AP04-1AA0 SIRIUS Power Contactor, 22 kW AC-","metaDescription":"Siemens SIRIUS 3RT1036-3AP04-1AA0 power contactor, S2 frame, 22 kW AC-2 at 400 V, 30 kW AC-3 at 500 V.

The 3RT1036-3AP04-1AA0 includes factory-fitted auxiliary contacts (the -3AP04 suffix). For a drop-in replacement without rewiring, verify the auxiliary contact configuration matches your control circuit. The main power ratings and mounting footprint are identical."},{"question":"What is the listed depth of this contactor?","answer":"The depth is 164 mm, measured from the DIN rail mounting surface to the furthest projection of the screw terminals."},{"question":"What solid wire sizes does it accept?","answer":"The main terminals accept 2x (0.25 to 2.5 mm²) solid wire. For stranded wire, the range is 2x (0.75 to 25 mm²)."},{"question":"Will it drop into a panel specified around 3RT1036-1AB00 without rewiring?","answer":"Yes, the mounting footprint (55 mm width, DIN rail snap-on) and main power terminal locations are identical. The difference is the auxiliary contact configuration — the -3AP04 suffix adds specific auxiliary contacts. If the original BOM called for a separate auxiliary contact block, this integrated version may simplify wiring. Verify the contact arrangement matches your control schematic."},{"question":"What compliance documentation is available?","answer":"The part is RoHS-compliant with a substance prohibition date of May 1, 2012, and REACH-compliant. It carries IP20 protection on the front and IP00 on the terminals. Pollution degree 3 per IEC 60947-1 applies. Standard Siemens SIRIUS documentation includes a CE declaration of conformity and UL/CSA file numbers."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1036-3AP04-1AA0","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/3RT1036-3AP04-1AA0 when reusing this data.
