Integrated bypass contact system means the thyristors are shorted out after start — the heat dissipated during continuous run is just the bypass contacts, not the silicon junction. ## Inside-delta wiring cuts line current by 58% Supports inside-delta circuit connection — the soft starter sits in the motor delta legs, so line current drawn is 58% of the motor FLA compared to standard inline wiring. For a 1 864 A unit that means the upstream contactor and cables see about 1 080 A. Adjustable current limitation lets you cap the start surge — set it between 8% and the full rating, which keeps the supply from dipping on weak grids or long cable runs up to 500 m. ## Termination and mounting — busbar or cable up to 500 kcmil Main current circuit accepts busbar connection or cable: stranded 70–240 mm², finely stranded 50–240 mm², or AWG 2/0–500 kcmil. Mounting by screw fixing, 780 mm high by 575 mm wide by 292 mm deep. The enclosure cutout must clear these; clearance above is 100 mm, below 75 mm, side 5 mm. ## Protection and diagnostics built in Motor overload protection and intrinsic device protection are integrated — no separate overload relay to size and wire. External reset input and a display for fault signals speed up troubleshooting on the line. Storage range -25 to +80 °C, operation up to 60 °C ambient. Lifecycle stage is current — Siemens still manufactures this soft starter. No stock-holding claim — quoted per order.","metaTitle":"Siemens 3RW4465-2BC45 SIRIUS Soft Starter, 1864 A, 690 V","metaDescription":"Siemens 3RW4465-2BC45 SIRIUS soft starter, rated 1864 A at 40 °C, 690 V insulation voltage, with integrated bypass and inside-delta circuit.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Soft Starters"],"specifications":{"Depth":"292mm","Solid":"2x (0.25 ... 1.5 mm²)","Width":"575mm","title":"3RW4465-2BC45","Height":"780mm","Upwards":"100mm","Stranded":"70 ... 240 mm²","Downwards":"75mm","Thyristors":"Yes","At The Side":"5mm","description":"SIRIUS soft starter Values at 500 V, 40 °C standard: 1076 A, 800 kW Inside-delta: 1864 A, 1350 kW 400-600 V AC, 230 V AC spring-type terminals!!!
