The AC-3e maximum switching frequency of 500 operations per hour tells you this is a general-purpose machine contactor, not a high-speed chopper; for high-cycling applications like rapid reversing, the AC-4 maximum of 130 ops/h is the limit. The insulation voltage is rated 1 000 V, and the pollution degree is 3 (conductive or dry non-conductive pollution), which is standard for industrial enclosures where some condensation occurs. Mounting is by screw fixing (not DIN-rail snap-on), so plan for a drilled backplate or mounting rail with tapped holes. Dimensions are 214 mm high, 160 mm wide, 225 mm deep — size S12 is a physically large contactor; verify panel door clearance and busbar routing before committing the layout. ## Coil and auxiliary supply The coil draws 6 A at 24 V rated value, 6 A at 230 V, and 3 A at 400 V — these are inrush or holding figures depending on the contactor design (typically a DC-operated AC coil with electronic control). The coil range is 96 … 127 V AC at both 50 and 60 Hz, so it works on 110–120 V control circuits common in North America and on 110 V European control schemes. The surge suppressor is designed with a varistor, which clips voltage spikes from the coil when de-energized; this is built in, so no external snubber is needed for standard inductive loads.","metaTitle":"Siemens 3RT5075-6NF36 SIRIUS Power Contactor, Size S12","metaDescription":"Siemens 3RT5075-6NF36 SIRIUS power contactor, size S12, screw terminals, 96-127V AC 50/60Hz coil.
