The contactor carries a 22 kW rating at 400 V under AC-2 duty, covering applications like slip-ring motor starting where the load current stays below the make/break rating. The AC-3 rating of 30 kW at 500 V covers the majority of standard squirrel-cage motor switching in industrial distribution. Mechanical life rated at 10,000,000 typical operations. Electrical switching rates: 1,000 cycles per hour at AC-1, 800 at AC-3, 300 at AC-4. Main current circuit terminals are screw-type, accepting solid conductors from 2x (0.5... 1.5 mm²) up to max. 2x (0.75... 4 mm²), and stranded conductors from 2x (0.75... 25 mm²). The wide stranded range — up to 25 mm² — accommodates the full load current for the 30 kW rating without needing parallel runs or oversized lugs. The contactor measures 55 mm wide by 112 mm high by 115 mm deep, fitting into a standard S2 footprint. ## Environmental and Protection Ratings The terminal area itself is rated IP00, so the contactor must be installed within an enclosure that provides the final system IP rating. The 60 °C upper operating limit allows installation near heat-producing equipment (drives, transformers) without forced cooling, as long as the enclosure ambient stays within that range.","metaTitle":"Siemens 3RT1036-1AC20-ZX95 SIRIUS Power Contactor, 55 mm, 30","metaDescription":"Siemens SIRIUS 3RT1036-1AC20-ZX95 power contactor, size S2, 30 kW at 500 V AC-3.
