Panel fit and physical constraints
The 3RT2036-1SF30 is a SIRIUS S2-size power contactor with a 55 mm width, 114 mm height, and 130 mm depth.
Reliability and operating duty
Listed MTBF is 52 a, which for a power contactor in continuous motor-switching service reflects the mechanical and electrical endurance margins built into the SIRIUS platform. 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.
