What this part is and where it lands
The Siemens SIRIUS 3RT1054-6AM36 is a power contactor in the S6 frame size, designed for switching motor loads and resistive loads in industrial control panels. It lands in the panel via screw fixing, with a vertical mounting surface that allows ±90° rotation and ±22.5° tilt front-to-back — useful when aligning contactors across a crowded backplate. The coil is rated 200-220 V AC at 50/60 Hz, and the main power terminals accept stranded cable from 25 to 120 mm², so this is sized for the higher-current end of the S6 range.
Panel fit and clearances
Footprint is 172 mm high by 120 mm wide by 170 mm deep. Minimum clearances: 10 mm upwards and downwards, 20 mm forwards, 10 mm at the sides.
Switching duty and operating rhythm
Maximum switching frequency depends on the duty category: 1 000 operations per hour in AC-3 and AC-3e (the standard motor-starting duty), 800 in AC-1 (resistive), 400 in AC-2 (slip-ring motor starting), and 130 in AC-4 (plugging/inching). For a typical conveyor motor running at AC-3, that's one start every 3.6 seconds at full rate — well within the margin for most line cycles. The mechanical life of the contactor is rated at 10 million operating cycles.
Coil and auxiliary contact specs
Coil pickup and dropout timing: 40 to 60 ms on both AC and DC supplies. Arcing time is 10 to 15 ms. The auxiliary contact ratings at 24 V are 10 A, dropping to 2 A at 48 V and 60 V, and 1 A at 110 V — these matter when the auxiliary feeds a PLC input or a holding circuit in a safety chain. The coil's full-scale value is 1.1 (likely the pickup multiplier above rated voltage), and the initial value is 0.8 (dropout threshold). Operating temperature range is -25 to +60 °C; storage range is -55 to +80 °C.
