The coil is rated for 575–600 VAC. The S12 frame handles stranded power cables from 70 up to 240 mm². Switching frequency varies by duty: AC-1 (resistive) allows up to 500 operations per hour, AC-3 (squirrel-cage motor start/run) allows 420 per hour, and AC-4 (plugging/inching) drops to 130 per hour. For a conveyor line cycling every 30 seconds, the AC-3 rate is fine; for a jogging station, you'll need to respect the AC-4 limit or the contactor will overheat. The envelope is 214 mm high, 160 mm wide, and 225 mm deep. That forward clearance is the one that catches people — if the panel door has a deep-mounted disconnect or a busbar shield, check that 20 mm before you commit the layout. The coil connection uses screw-type terminals, and the auxiliary wiring accepts 2x (0.5–1.5 mm²) solid or 2x (0.75–2.5 mm²) stranded, with a maximum of 2x (0.75–4 mm²). Standard ferrule sizes fit; no special crimp tool needed.","metaTitle":"Siemens 3RT1076-6AT36 SIRIUS Power Contactor, S12 Frame, 575","metaDescription":"Siemens SIRIUS 3RT1076-6AT36 power contactor, S12 frame, 575-600 VAC coil, screw fixing.
