The contactor also carries a 11.4 kW rating at 690 V, so it can handle higher-voltage motor circuits in 690 V industrial networks. Auxiliary contact ratings cover 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V, which covers most PLC output and relay interposing circuits you'd wire into the control loop. The main circuit uses screw-type terminals, and the coil is rated for 400 V at 50 Hz and 400-440 V at 60 Hz, with an operating range of 0.8 to 1.1 times rated voltage at 50 Hz and 0.85 to 1.1 at 60 Hz — so it holds in during brownout conditions down to about 320 V. The contactor measures 55 mm wide, 112 mm high, and 164 mm deep, and mounts via screw and snap-on onto a 35 mm DIN rail per EN 50022. That's a standard footprint for the S2 frame — it'll drop into any panel with the rail already laid out. For mixed solid/stranded, it handles 2x 0.75 to 16 mm². That covers everything from control wiring up to motor power tails in a typical 30 kW circuit. The front of the contactor is IP20 — safe for finger-probe access inside the panel — while the terminal area is IP00, meaning live parts are exposed at the connection point, which is standard for enclosed contactors. ## Environmental and service life Operating temperature range is -25 to +60 °C, storage from -55 to +80 °C, with pollution degree 3 — suitable for industrial environments with conductive dust or occasional condensation. Maximum switching frequencies vary by duty: 1000 cycles/h for AC-1 resistive loads, 800 for AC-3 motor starting, 400 for AC-2, and 300 for AC-4 plugging/reversing. The coil operating time is 7 to 20 ms AC, with arcing time 10 to 15 ms.","metaTitle":"Siemens 3RT1036-1AR64 SIRIUS Power Contactor, S2, 30 kW at 5","metaDescription":"Siemens SIRIUS 3RT1036-1AR64 power contactor, size S2, rated 30 kW at 500 V, 22 kW at 400 V AC-2.
