The integrated bypass contact system means the thyristors are shorted out once the motor reaches full speed, dropping heat dissipation in the enclosure and eliminating continuous conduction losses. For a 1065 A load, that's the difference between needing forced ventilation and running passive convection in a standard IP20 cabinet. ## Protection and control features Built-in motor overload protection, intrinsic device protection, and adjustable current limitation are all standard on this unit. The minimum load setting of 8 % means it handles lightly loaded conveyors or pumps without nuisance trips. An external reset input and a display for fault signals simplify troubleshooting on the line — no need to crack the panel to read a blinking LED code. ## Mounting and wiring constraints This is a large-frame unit: 640 mm high, 510 mm wide, 290 mm deep, mounted with screw fixing. The mounting position allows vertical surface mounting with ±90° rotation and ±22.5° tilt front/back — useful when you're squeezing it into an existing lineup. Main circuit connection is busbar, with the main cable range from 2/0 to 500 kcmil. Auxiliary and control wiring uses spring-loaded terminals accepting 24–16 AWG solid or stranded. Clearance: 100 mm upward, 75 mm downward, 5 mm at the sides — the side clearance is tight, so plan the gland plate accordingly.","metaTitle":"Siemens 3RW4454-2BC46 Soft Starter, 1065 A, SIRIUS","metaDescription":"Siemens SIRIUS 3RW4454-2BC46 soft starter, 1065 A at 40 °C, 690 V insulation, inside-delta circuit, integrated bypass.
