It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 50022, and the mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward or backward — useful when fitting into a crowded enclosure. The AC-3 maximum switching frequency is 800 operations per hour; under AC-4 duty that drops to 250 operations per hour — a real constraint if you're jogging or plug-reversing a motor frequently. Side-by-side mounting is allowed, which helps when building multi-contactor motor starter banks. ## Coil and auxiliary circuit details Control supply voltage is AC only. The magnet coil draws 0.79 W closing power and holds at 0.36 W DC — that's the steady-state dissipation you need to account for in the control transformer sizing. Auxiliary contacts are rated for PLC-level reliability: the contact reliability spec says they're acceptable for PLC control at 17 V, 5 mA. That means you can drive a 24 V DC PLC input directly without worrying about oxide film on the contacts. Both main and auxiliary circuits use screw-type terminals. The main circuit accepts 2x (0.5…1.5 mm²) or 2x (0.75…2.5 mm²) solid or stranded wire, same for finely stranded with ferrules. That's a standard range for control panel wiring — no oddball lug sizes.","metaTitle":"Siemens 3RT7036-1AQ00 Contactor, S2, 3-pole, AC coil, 55 mm","metaDescription":"Siemens 3RT7036-1AQ00 S2 contactor, 3-pole, AC coil, screw terminals, IP20 front, 55 mm wide, 115 mm deep.
