Rated insulation voltage is 690 V, and motor power ratings reach 18 kW at 230 V, 31 kW at 400 V, and 54 kW at 690 V (all at 60 °C ambient). The 110 VDC coil draws 13.3 W closing and holding power, with a pick-up current of 6 A at 24 V and 1 A at 110 V. Screw-type terminals on both main and auxiliary/control circuits accept 2x (0.75–16 mm²) solid or stranded conductors (2x 18–2 AWG). Minimum cross-section at 40 °C is 16 mm²; at 60 °C it derates to 10 mm². Side-by-side mounting is permitted, so multiple contactors can pack tightly on the rail. The auxiliary switch extension is available as a product option, allowing add-on contact blocks without rewiring the main circuit. Dimensions are 55 mm wide, 112 mm high, 130 mm deep — the S2 frame fits standard panel cutouts and leaves room for wiring ducts alongside. Maximum switching frequency varies by duty: 1,200 operations/hour at AC-1 (resistive), 1,000 ops/h at AC-3 (motor starting), 250 ops/h at AC-4 (inching/plugging), and 1,500 ops/h at DC.","metaTitle":"Siemens 3RT5034-1BF40 SIRIUS Power Contactor, 110 VDC Coil,","metaDescription":"Siemens SIRIUS 3RT5034-1BF40 power contactor, S2 size, 110 VDC coil, 690 V insulation voltage, screw terminals.
