It's rated for 22 kW at AC-2 duty on 400 V, which covers wound-rotor motors and other moderate-inductive loads that need controlled acceleration. For the heavier AC-4 duty (plugging, inching, reversing) it handles 41 A at 400 V, so it can manage the high-stress switching cycles those applications demand. The coil is 24 V 50 Hz, a common control voltage that keeps panel wiring straightforward. ## Mounting and wiring — what fits where Dimensions are 55 mm wide, 112 mm high, 115 mm deep, which is the S2 frame footprint. At 40 °C the minimum permissible conductor is 16 mm², so plan your cable lugs accordingly. ## Switching performance and operating conditions Arcing time runs 10 to 15 ms, and the contactor can handle up to 1,000 operations per hour in AC-1 (resistive) duty, 800 in AC-3 (squirrel-cage motor start/run), and 300 in AC-4 (plugging/reversing). Auxiliary contact ratings cover the common control voltages: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 0.3 A at 220 V DC.","metaTitle":"Siemens 3RT1036-1AB00 SIRIUS S2 Power Contactor, 22 kW AC-2","metaDescription":"Siemens 3RT1036-1AB00 SIRIUS S2 power contactor.
