AC-3 maximum switching rate is 800 operations per hour, AC-4 maxes at 300 ops/h — the lower AC-4 figure reflects the heavier arc duty of plugging and inching. The coil operating range spans 0.8 to 1.1 times rated voltage at 50 Hz, and 0.85 to 1.1 at 60 Hz — pick-up is assured down to 80 % of nominal, which matters on weak or long-feed control circuits. Auxiliary contact ratings: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 0.3 A at 220 V DC — the DC derating is steep, so if you are switching a DC-piloted valve bank at 220 V, verify the 0.3 A limit covers the inrush.","metaTitle":"Siemens 3RT1036-3AL20 SIRIUS Power Contactor, 22 kW AC-2, 50","metaDescription":"Siemens SIRIUS 3RT1036-3AL20 power contactor, size S2, 22 kW at 400 V AC-2, 50/60 Hz, screw terminals, snap-on DIN rail.
