For AC-4 duty — plugging and inching — it delivers 29 A at 400 V, a rating that governs the contactor's life under frequent reversals. AC-3 performance reaches 18.5 kW at 500 V and 10 kW at 690 V, covering standard squirrel-cage motor starts. ## Termination and Environmental Fit Solid conductors accept 2x (0.25 to 2.5 mm²); stranded conductors accept 2x (0.75 to 25 mm²). A separate solid-or-stranded range of 2x (0.75 to 16 mm²) is also listed, so verify the specific wire gauge against the terminal marking on delivery. The terminal area is rated IP00, meaning the connection points are unprotected — the contactor must be mounted inside a cabinet or guarded panel. Side-by-side mounting is permitted, which simplifies multi-contactor assemblies without derating for thermal stacking. The product carries the SIRIUS brand from Siemens, and its approvals (UL, CSA, CE) are standard for this series, though specific certification numbers are not listed in this record.","metaTitle":"Siemens 3RT1034-3AD00 SIRIUS S2 Power Contactor, 15 kW at AC","metaDescription":"Siemens 3RT1034-3AD00 SIRIUS S2 power contactor, 15 kW at AC-2 400 V, 29 A at AC-4 400 V.
