It also carries a 30 kW rating at 500 V. The 55 mm width means it takes three standard DIN modules. Terminals are screw-type on the main circuit, accepting up to 2x 25 mm² stranded — wires up clean for a 22 kW motor feed. The auxiliary circuit handles 2x 2.5 mm² solid. AC-3 maximum switching frequency is 800 cycles per hour; AC-4 (plugging/inching) drops to 300 1/h. The contactor is rated for 10 million mechanical operations typical, so it outlasts most panel builds in normal cycling.","metaTitle":"Siemens 3RT1036-3AN20 SIRIUS Power Contactor, 22 kW AC-2","metaDescription":"Siemens SIRIUS power contactor 3RT1036-3AN20, current production. 22 kW at AC-2 400 V, screw terminals, 55 mm wide.
