SIRIUS power contactor, size S6 — 3RT1054-1PP35
The coil is rated for 200-277 VAC, and the contactor accepts stranded power cables from 16 to 70 mm² — that covers most motor feeds up to about 55 kW at 400 V, depending on duty.
That same rate applies under AC-3e (enhanced) as well. Under AC-4 (plugging/inching) the rate drops to 130 ops/h, so if your application involves frequent reversing or jogging, you'll need to account for that lower duty. The mechanical life is typical for the class at 10 million operations. Mounting is screw-fix to a vertical surface; the contactor can be rotated ±90° or tilted ±22.5° front-to-back, which gives flexibility in tight enclosures. Clearances: 10 mm upwards, downwards, and to the side; 20 mm forwards — that's the arcing zone, so don't crowd it against sheet metal or other devices. Coil pickup and dropout timing is 80-90 ms on both AC and DC supplies, with arcing time 10-15 ms. The coil hold-in power factor is 0.6 at both 50 and 60 Hz. The rated value of 200-277 VAC covers most European and North American control voltages in that band.
