Mounting is by screw fixing with the vertical mounting surface rotatable ±90° and tiltable ±22.5° front-to-back. Clearance requirements: 100 mm above, 75 mm below, 5 mm at the sides. The unit measures 780 mm high × 575 mm wide × 292 mm deep — this is a large-frame soft starter that needs a dedicated enclosure bay. ## Protection and control features Motor overload protection and intrinsic device protection are built in — no separate overload relay needed for most installations. Adjustable current limitation lets you set the start current between 8% and full load, useful for soft-starting conveyors or pumps where mechanical shock must be limited. The inside-delta circuit configuration is supported, which reduces the thyristor current rating requirement by 42% compared to standard in-line wiring — a key detail for retrofits where the motor is already wired in delta. External reset input and a display for fault signals simplify troubleshooting on the line.","metaTitle":"Siemens 3RW4465-6BC45 SIRIUS Soft Starter, 1864 A, 690 V","metaDescription":"Siemens 3RW4465-6BC45 SIRIUS soft starter, 1864 A at 40 °C, 690 V insulation.
