That AC-2 figure tells you it's built for slip-ring motors or other loads where the contactor opens under current — the arcing time sits at 10 to 15 ms, so it clears fast without welding the main poles shut. The screw terminals accept solid wire up to 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²), and stranded up to 2x (0.75 to 25 mm²). That's a wide range, so you can land motor leads or control wiring without adapters. ## Environmental & Protection The front of the contactor carries an IP20 rating — safe from finger contact once it's inside the enclosure. The terminal area is IP00, meaning the connection points are exposed, so it needs to live behind a panel door or cover. Operating temperature range is -25 to +60 °C, storage from -55 to +80 °C, and it's rated for pollution degree 3 — that's the industrial environment where conductive dust or moisture could be present.","metaTitle":"Siemens 3RT1036-1AD20-1AA0 SIRIUS Power Contactor, Size S2,","metaDescription":"Siemens SIRIUS 3RT1036-1AD20-1AA0 power contactor, size S2, rated 22 kW at AC-2 400 V.
