The coil is rated 96-127 V AC/DC, with a pick-up threshold of 0.8 x rated value and a drop-out of 0.4 x rated value at both 50 Hz and 60 Hz. The MTBF of 75 a (657,000 hours) is the mean time between failures under typical operating conditions — a reliability figure that matters for maintenance planning in continuous-process lines. The contactor is rated for switching frequencies up to 200 operations per hour in AC-1, AC-3, and AC-3e duty, and 170 ops/h in AC-2; AC-4 (plugging/reversing) is limited to 130 ops/h. Power connections accept stranded cable from 70 to 240 mm² — sized for main feeder circuits. The auxiliary contacts handle 10 A at 24 V, 2 A at 48 V, and 2 A at 60 V. Clearance distances: 10 mm upwards, downwards, and sideways; 20 mm forwards. The mounting holes are 11 mm diameter, single hole per fixing point.","metaTitle":"Siemens 3RT1076-6SF36-3PA0 SIRIUS Power Contactor, Size S12","metaDescription":"Siemens 3RT1076-6SF36-3PA0 SIRIUS power contactor, Size S12.
