The vacuum arc-quenching technology means the contacts switch in a sealed vacuum bottle, giving it a typical mechanical endurance of 10,000,000 operations. The coil is rated for 96-127 V AC/DC, with screw-type terminals for the magnet coil connection. Main pole wiring accepts stranded conductors from 70 mm² up to 240 mm², making it suitable for high-current motor circuits. ## Mounting and panel integration constraints Fastening is by screw fixing through a single 11 mm diameter hole. The contactor measures 210 mm high, 145 mm wide, and 206 mm deep. Mounting position allows ±22.5° rotation on a vertical surface, and it can be tilted forward/backward by ±22.5° on a vertical surface, or mounted standing on a horizontal surface. Minimum clearances around the contactor: 10 mm upwards, 20 mm forwards, 10 mm downwards, and 10 mm at the side. These are the air and creepage distances needed for the rated voltages — plan your enclosure layout accordingly. ## Switching performance and duty cycle limits Maximum switching frequency varies by duty class: 800 operations/hour in AC-1 (resistive), 300/h in AC-2, 750/h in AC-3 and AC-3e, and 250/h in AC-4 (plugging/inching). The arcing time is 10-15 ms, and the operating time for both AC and DC coil supply is 80-100 ms. The auxiliary switch is present, with rated values of 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, and 1 A at 110 V. These are the contact ratings for the built-in auxiliary contacts — size your control circuit loads against these limits. ## Environmental operating range and lifecycle status Operating temperature range is -25 to +60 °C; storage range is -55 to +80 °C. The power factor is 0.4 at both 50 Hz and 60 Hz. The initial operating value is 0.8 of rated voltage, and the full-scale value is 1.1 — this defines the coil pick-up and drop-out voltage window.","metaTitle":"Siemens 3RT1264-6NF36 SIRIUS Vacuum Contactor, S10","metaDescription":"Siemens 3RT1264-6NF36 SIRIUS vacuum contactor, size S10, 96-127 V AC/DC coil.
