The S2 frame keeps it compact at 55 mm wide, 114 mm tall, 174 mm deep, fitting standard 35 mm DIN rail per DIN EN 60715 with screw or snap-on mounting. ## Duty-cycle and switching frequency Maximum switching rates depend on the duty class: 1 000 cycles/hour for AC-1 (resistive loads), 800 for AC-3 (motor starting/running), 600 for AC-2 (slip-ring motors), and 250 for AC-4 (plugging/inching). The AC-3e rating also sits at 800 cycles/hour. For a conveyor or pump running continuous start/stop cycles, stay under the AC-3 limit to keep contact life at the typical 10 million operations. Main contacts are 3-pole normally open (18...1 configuration). Screw terminals accept 2x (0.5...1.5 mm²) or 2x (0.75...2.5 mm²) solid or stranded wire. ## Environmental and auxiliary ratings The magnet coil uses screw-type terminals. Auxiliary contact ratings at 24 V: 6 A; 48 V: 2 A; 60 V: 2 A; 110 V: 1 A; 125 V: 0.9 A; 220 V: 0.3 A; 400 V: 3 A; 440 V: 0.6 A. Arcing time is 10...20 ms; switching time at AC is 10...18 ms. Power factor at 50 Hz is 0.36, at 60 Hz is 0.39.","metaTitle":"Siemens 3RT2036-1AR64 SIRIUS S2 Power Contactor, 52 A AC-3 a","metaDescription":"Siemens SIRIUS 3RT2036-1AR64 S2 power contactor, 52 A AC-3 at 480 V, screw terminals, 55 mm wide, active production.
