The AC-3e rating matches the AC-3 figure at 1,000 ops/h. If your application requires frequent jogging or reversing, the AC-4 limit governs the duty cycle. Auxiliary contact ratings span the control voltage range: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, 0.6 A at 440 V, and 40 A at 480 V. The 40 A figure at 480 V is the make/break capacity for that voltage class — verify your control transformer fuse sizing against the lower continuous rating. The storage range is wider because the contactor isn't under load; the operating range is the one that governs panel ambient temperature. Arcing time is 10 to 20 ms, and the closing time (at AC) is 10 to 18 ms. These numbers matter for coordination with upstream short-circuit protection and for timing interlock circuits. Power factor at 50 Hz is 0.36, at 60 Hz is 0.39 — this is the coil power factor, not the motor load. It affects the VA burden on the control transformer. Terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded wire — standard for panel wiring with ferruled conductors. The screw-type coil terminals are the same gauge range.","metaTitle":"Siemens 3RT2035-1AK60-1AA0 SIRIUS Power Contactor, Size S2,","metaDescription":"Siemens 3RT2035-1AK60-1AA0 SIRIUS power contactor, Size S2, 110V 50Hz coil, screw terminals, auxiliary switch included.
