Depth is 73 mm, height 58 mm — that leaves clearance for wiring ducts and adjacent components in a crowded enclosure. The coil connection uses screw-type terminals — no push-in here, so you'll need a torque screwdriver for the terminal screws. ## Switching capacity — 20-12 A main contacts, auxiliary present The main contact range is rated 20-12 A — that's the continuous current envelope for AC-3 motor switching duty. An auxiliary switch is built in, saving the cost and rail space of a separate auxiliary contact block for basic feedback or interlocking. Mechanical endurance is 30 million cycles typical — that's a long service life for a contactor that cycles a few times per hour in a conveyor or compressor application. Maximum switching rate in AC-3 duty is 750 operations per hour; in AC-4 (inching/jogging) it drops to 250 per hour — stay below these limits to avoid contact welding. ## Sourcing — current production, quoted to order This part is sourced through authorized Siemens distribution channels and quoted to order against your BOM quantity.","metaTitle":"Siemens 3RT2018-1AV61-0UA0 SIRIUS Contactor, Size S00","metaDescription":"Siemens 3RT2018-1AV61-0UA0 SIRIUS power contactor, size S00, 45 mm wide, screw terminals, 30M mechanical cycles, current production.
