The AC-4 rating of 41 A at 400 V tells you it's built for the tough inching and plugging duty cycles that eat lesser contactors alive — frequent starts, reversals, and counter-current braking. AC-3 maximum switching frequency is 800 operations per hour, so it keeps up with a busy conveyor or pump station without complaint. Coil arcing time runs 10 to 15 ms, with a DC dropout band of 20 to 25 ms — numbers that matter when you're coordinating contactor timing in a safety circuit or sequencing multiple starters. The IP20 front and IP00 terminal rating means it's meant for enclosure mounting, not open-panel washdown areas. Screw terminals accept solid conductors from 2x (0.25 to 2.5 mm²) and stranded from 2x (0.75 to 25 mm²), with a minimum 16 mm² at 40 °C. That's enough cross-section for the full rated current without derating headaches. Substance prohibitance date of 05/01/2012. No UL or CSA mark is listed in the evidence.","metaTitle":"Siemens 3RT1036-3BM40 SIRIUS Power Contactor, S2, 30 kW at 5","metaDescription":"Siemens 3RT1036-3BM40 SIRIUS power contactor, S2 size.
