The coil draws 10 A at 24 V rated value and 6 A at 230 V rated value, with a rated frequency of 50 Hz. Width of 55 mm, height 112 mm, depth 164 mm; side-by-side mounting permitted, so multiple contactors pack tightly on the rail without derating. Main circuit terminals are screw-type, accepting solid 2x (0.25 … 2.5 mm²) and stranded 2x (0.75 … 25 mm²). Current-production part — no obsolescence notice on record. Degree of pollution 3, IP20 on the front (finger-safe behind the panel door), IP00 at the terminals (inside the enclosure).","metaTitle":"Siemens 3RT1036-3AF04 SIRIUS Power Contactor, S2, 22 kW AC-2","metaDescription":"Siemens 3RT1036-3AF04 SIRIUS power contactor, size S2, rated 22 kW at AC-2 400 V and 41 A at AC-4 400 V.
