Typical mechanical life is 5,000,000 operations. Maximum operating rates vary by duty: 1,000 cycles/hour at AC-1, 800 cycles/hour at AC-3 and AC-3e, 600 cycles/hour at AC-2, and 250 cycles/hour at AC-4. The arcing time is 10–20 ms, and the switching times at both AC and DC are 30–55 ms. ## Coil and auxiliary details The magnet coil uses screw-type terminals and is rated for 83–150 V AC/DC with an inrush current peak of 25 A. Holding power at 50/60 Hz is 2 VA. The coil includes an auxiliary switch and a main contact configuration of 18 NO plus 1 NC.","metaTitle":"Siemens 3RT2036-1SF30 SIRIUS Power Contactor, S2 Size","metaDescription":"Siemens 3RT2036-1SF30 SIRIUS power contactor, S2 size, 55 mm width, 114 mm height, 130 mm depth.
