This \u003cstrong\u003e3RW4458-6BC44\u003c\/strong\u003e module controls motor acceleration and deceleration, reducing mechanical stress and electrical surges. It is a phased-out product, with the preferred successor being the \u003cstrong\u003eSiemens 3RW5556-6HA14\u003c\/strong\u003e of the SIRIUS 3RW5 series.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eProduct brand name: SIRIUS\u003c\/li\u003e\n\u003cli\u003eOperational current at 40 °C: 970 A\u003c\/li\u003e\n\u003cli\u003eAt inside-delta circuit at 40 °C: 1680 A\u003c\/li\u003e\n\u003cli\u003eYielded mechanical performance at 400 V standard circuit: 560 kW\u003c\/li\u003e\n\u003cli\u003eOperating voltage: 200...460 V AC\u003c\/li\u003e\n\u003cli\u003eControl supply voltage: 230 V AC at 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003ePower loss typical at 40 °C: 270 W\u003c\/li\u003e\n\u003cli\u003eWidth: 510 mm, Height: 640 mm, Depth: 290 mm\u003c\/li\u003e\n\u003cli\u003eProtection class: IP00\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eIndustry Applications\u003c\/h2\u003e\u003cp\u003eThe \u003cstrong\u003eSiemens 3RW4458-6BC44\u003c\/strong\u003e is suited for heavy-duty motors in conveyors, pumps, and compressors. In standard circuit at 400 V, it delivers 560 kW, while inside-delta circuit reaches 1000 kW. Its adjustable current limitation and motor overload protection make it reliable for mining, water treatment, and manufacturing.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Setup Guidance\u003c\/h2\u003e\u003cp\u003eMount the \u003cstrong\u003eSiemens 3RW4458-6BC44\u003c\/strong\u003e using its screw fixing method.
