It mounts via screw and snap-on onto 35 mm DIN rail per EN 50022, with the mounting position allowing ±180° rotation on a vertical surface and ±22.5° tilt forward or backward. ## Coil and control — AC drive, DC holding The control supply voltage is AC. Closing power of the magnet coil at DC is 0.79 W; holding power drops to 0.36 W. The auxiliary contact block is rated for PLC-level reliability (17 V, 5 mA), meaning it can switch low-energy signals without oxide-film issues — useful when feeding a digital input card directly. ## Fuse coordination and short-circuit protection For type of coordination 2 the required backup fuse is gL/gG NH 3NA rated 100 A. For type of coordination 1 it's 160 A. Both main and auxiliary/control circuits use screw-type terminals. The main circuit accepts 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded wire, and the same range for finely stranded with core-end processing. Side-by-side mounting is permitted, which helps when packing multiple contactors on a DIN rail.","metaTitle":"Siemens 3RT7037-1AV00 S2 Contactor, 3-Pole, AC Coil, 690V AC","metaDescription":"Siemens 3RT7037-1AV00 Size S2 contactor, 3 NO main contacts, AC coil, 690 V AC-3 max.
