Rated for 6 A at 230 V AC, 3 A at 400 V, and 1 A at 690 V, so it handles the inrush from discharged capacitors without welding the main poles. The 45 mm width and 135 mm height mean it occupies a single standard module slot — no special adapter needed. Depth of 165 mm leaves clearance for wiring behind the panel door. Screw terminals accept solid conductors: 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), or 2x 4 mm². Stranded: 2x (1–2.5 mm²) or 2x (2.5–10 mm²). At 40 °C ambient, a single 10 mm² conductor is the limit; at 60 °C, two 10 mm² conductors are allowed. That covers most panel-building practices for a contactor this size — no need for ring-tongue adapters on the main poles.","metaTitle":"Siemens 3RT2627-1BF45 SIRIUS Capacitor Contactor, S0, 24 VDC","metaDescription":"Siemens 3RT2627-1BF45 SIRIUS capacitor contactor, size S0, 24 VDC coil, screw terminals.
