For heavy jogging or plugging duty (AC-4), it's rated 41 A at 400 V. Substance prohibitance dates to 05/01/2012, indicating RoHS and REACH compliance. No separate UL or IEC listing is in the evidence, but the SIRIUS series typically carries those approvals; verify the specific certification needed for your jurisdiction against the nameplate. Main circuit terminals accept solid wire from 2x (0.5 to 1.5 mm²) up to 2x (0.75 to 4 mm²) for the control side, and stranded from 2x (0.75 to 25 mm²) for the power side. At 40 °C the minimum permissible conductor is 16 mm² — that's the thermal sizing for full rated current. ## Dimensions and switching performance Physical footprint: 55 mm wide, 112 mm tall, 179 mm deep. That depth matters when you're fitting it into a shallow back panel — measure your enclosure depth before you commit. Coil dropout time at DC is 20 to 25 ms, and arcing time runs 10 to 15 ms. That's fast enough for most safety circuits, but if you're coordinating with a upstream breaker for Type 2 coordination, check the let-through energy curves. Maximum switching frequency: 1000 cycles/hour at AC-1, 800 at AC-3, 400 at AC-2, 300 at AC-4 — so it's fine for frequent starting but not for continuous high-speed jogging.","metaTitle":"Siemens 3RT1036-1BG44 SIRIUS Power Contactor, Size S2, 30 kW","metaDescription":"Siemens 3RT1036-1BG44 SIRIUS power contactor, Size S2, rated 30 kW at 500 V AC-3, 22 kW at 400 V AC-2, 41 A at 400 V AC-4.
