The AC-4 rating of 41 A at 400 V covers plugging and inching duty, which is harder on the contacts than standard AC-3 starting. If your application cycles through reversals or jogging, the AC-4 number is the one that governs contact life, not the AC-2 kW figure. On the DC side, the contactor switches 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — these are resistive-load ratings. The Size S2 frame (112 mm high, 55 mm wide, 164 mm deep) fits the standard S2 footprint, so it swaps into existing S2 backplates without drilling. ## Terminal wiring and environmental limits Main circuit terminals accept stranded wire up to 2x 25 mm², solid up to 2x 16 mm², and the control circuit takes solid 2x 0.5 to 4 mm². That's enough for the full rated current on 16 mm² copper at 40 °C ambient — the minimum permissible cross-section is 16 mm² at 40 °C, so don't undersize the feed. The enclosure is IP20 on the front (finger-safe) and IP00 at the terminals — the connection points are live when the panel door is open, which is standard for contactors but worth flagging for lockout/tagout procedure. RoHS compliance date is May 1, 2012 — the part is fully RoHS-compliant and carries the standard SIRIUS declaration of conformity. No REACH SVHC or UL file number appears in this listing, but the SIRIUS series typically holds UL/CSA/CE certification; verify the specific UL file for your jurisdiction at quote.","metaTitle":"Siemens 3RT1036-1AP04 SIRIUS Power Contactor, 22 kW AC-2 at","metaDescription":"Siemens 3RT1036-1AP04 SIRIUS Size S2 power contactor. 22 kW AC-2 motor rating at 400 V, 41 A AC-4.
