Side-by-side mounting is allowed — no derating gap needed between contactors on the same rail. The 38 kW at 400 V 60 °C is the motor rating you size against — that's the AC-3 duty curve for a standard three-phase induction motor. At 690 V the same contactor handles 66 kW, so it carries higher-voltage motor circuits without stepping up frame size. The 230 V rating comes in at 22 kW. Electrical switching frequency tops out at 5,000 cycles per hour at AC, with AC-3 maximum at 800 cycles per hour and AC-4 at 300 cycles per hour — the AC-4 figure governs plugging or inching duty. Coil draws 6 A at 24 V rated value, 1 A at 110 V, and 0.3 A at 220 V.","metaTitle":"Siemens 3RT5036-1AL20 SIRIUS Power Contactor, 38 kW at 400 V","metaDescription":"Siemens 3RT5036-1AL20 SIRIUS S2 power contactor, 38 kW at 400 V 60 °C.
