It occupies a 170 x 120 x 172 mm footprint and mounts via screw fixing on a vertical surface with ±90° rotation or ±22.5° tilt allowance. The coil pull-in and drop-out times are both 80-90 ms, with an arcing time of 10-15 ms — figures to factor into your PLC scan-cycle coordination if the contactor drives a motor directly. The Size S6 frame and 16-70 mm² stranded-wire capacity tell you this is a heavy-duty power contactor, not a compact auxiliary relay — sized for motor loads up to the AC-3 switching frequency of 1 000 operations per hour (AC-3e maximum also 1 000 1/h). The 21-27.3 V coil range covers nominal 24 VDC systems with margin for brownout; the 0.8 initial-value factor means the coil picks up reliably at 80% of rated voltage. ## Wiring & panel integration Screw-type terminals on the coil accept 2x (0.5-1.5 mm²) solid or 2x (0.75-2.5 mm²) stranded, max 2x (0.75-4 mm²). Main power poles take stranded 16-70 mm² — expect lugs or pin ferrules for the larger gauges. The auxiliary switch is included (yes), so no separate add-on block for status feedback. Clearance distances: 10 mm upwards, 20 mm forwards, 10 mm sideways, 10 mm downwards — plan your DIN-rail or backplate layout accordingly.","metaTitle":"Siemens 3RT1054-1NB36 SIRIUS Power Contactor, Size S6, 21-27","metaDescription":"Siemens SIRIUS 3RT1054-1NB36 power contactor, Size S6, coil 21-27.3 VDC, screw terminals, 16-70 mm² stranded.
