That's the number that matters for a pump or conveyor drive in a warm enclosure — the spec table also lists 22 kW at 230 V and 66 kW at 690 V under the same 60 °C condition, but the 400 V figure is what most European panels will use. Rated for 5,000 operations per hour at AC duty, with AC-3 maximum at 800 cycles per hour and AC-4 at 300. ## Wiring and protection Main terminals accept 2x (0.75 to 16 mm²) solid or stranded, or 2x (18 to 2 AWG). The recommended gL/gG fuse for type 2 coordination is 80 A. ## Compliance and substance restrictions The part carries a substance prohibitance date of March 1, 2017, which aligns with RoHS and REACH compliance milestones. For documentation, Siemens provides a CE declaration and typically UL/CSA certification on the SIRIUS line — the 3RT5036 frame is listed under UL 508 and CSA C22.2 No. 14. If your quality doc control needs a specific certificate number, the nameplate carries the traceability data. This is an active-production part, not a liquidation gamble. If you're filling a BOM line or replacing a failed unit in a panel, the 55 mm width and screw terminals mean it swaps into the same footprint as other Size S2 contactors without rewiring the gland plate.","metaTitle":"Siemens 3RT5036-1AF00 SIRIUS Power Contactor, Size S2, 55 mm","metaDescription":"Siemens SIRIUS 3RT5036-1AF00 power contactor, Size S2, 55 mm wide, rated 38 kW at 400 V 60 °C.
