Insulation voltage is 690 V, operating frequency 50/60 Hz. ## Integrated bypass and overload — one device, fewer parts An integrated bypass contact system shunts the thyristors once the motor is at speed, eliminating the external bypass contactor and reducing heat dissipation in the panel. Motor overload protection and intrinsic device protection are built in — no separate overload relay needed. The inside-delta circuit capability lets you wire a six-lead motor in delta configuration, reducing line current by about 58% compared to standard in-line starting — a real advantage for large motors where cable sizing and breaker ratings are tight. ## Mounting and wiring — panel space and connection planning Dimensions are 780 mm high, 575 mm wide, 292 mm deep. Fastening is screw fixing with a vertical mounting surface; the unit can be rotated ±90° or tilted ±22.5° front/back. Clearance requirements: 100 mm upwards, 75 mm downwards, 5 mm at the sides. Main current circuit uses busbar connection — expect bus work, not cable lugs. Stranded cable range is 70–240 mm², finely stranded 50–240 mm², and AWG/kcmil 2/0–500 kcmil.","metaTitle":"Siemens 3RW4465-2BC34 SIRIUS Soft Starter, 1,864 A, 690 V","metaDescription":"Siemens 3RW4465-2BC34 SIRIUS soft starter, 1,864 A at 40 °C, 690 V insulation voltage.
