That 45 mm width is the standard S0 DIN-rail slot — it snaps onto the rail and can also be screw-mounted. Clearance: 60 mm above and 40 mm below for ventilation; 15 mm at the sides. ## Integrated bypass and control supply flexibility The built-in bypass contactor shorts the thyristors after start, dropping the heat dissipation to near zero during run — a meaningful advantage in a sealed panel. Control supply accepts 110-230 V DC, wide enough to work across common DC bus voltages without a separate power supply. No external reset and no motor overload protection integrated — plan for a separate overload relay upstream.","metaTitle":"Siemens 3RW3027-1BB14 Soft Starter, 32 A, S0 Frame, 600 V","metaDescription":"Siemens 3RW3027-1BB14 SIRIUS soft starter, 32 A at 40°C, 600 V rated insulation, S0 frame with integrated bypass.
