For heavy inching or plugging, the AC-4 rating is 35 A at 400 V. The screw-type terminals on the main circuit accept solid conductors from 0.25 to 2.5 mm² (two per clamp) and stranded from 0.75 to 25 mm² (two per clamp). At 40 °C the minimum permissible cross-section is 16 mm² for the main circuit. ## Environmental and protection The front of the contactor is IP20; the terminals are IP00 (no finger-safe protection at the wiring point).","metaTitle":"Siemens 3RT1035-3AV00 SIRIUS Power Contactor, 22 kW at 500 V","metaDescription":"Siemens 3RT1035-3AV00 SIRIUS power contactor, size S2, 22 kW at 500 V AC-3, 18.5 kW AC-2 at 400 V.
