Inside-delta circuit capability lets you wire the starter between the motor windings in a six-lead motor, reducing the current the soft starter sees by about 42% compared to standard in-line wiring. That means a smaller frame size for the same motor FLA — worth checking if your motor has accessible winding ends. ## Mounting and connections — screw fixing, busbar, and spring-clamp terminals Mounting is by screw fixing with the unit oriented vertically; it can be rotated ±90° or tilted ±22.5° front/back — so you can fit it into a tight panel corner as long as the ventilation clearances (100 mm up, 75 mm down, 5 mm sides) are respected. Main current circuit connection is busbar, sized for 2/0 to 500 kcmil or 70–240 mm² stranded.","metaTitle":"Siemens 3RW4465-2BC35 SIRIUS Soft Starter, 1864 A at 40 °C","metaDescription":"Siemens 3RW4465-2BC35 SIRIUS soft starter, 1864 A at 40 °C, integrated bypass, inside-delta capable.
