It is designed for smooth, controlled starting of three-phase AC motors — reducing inrush current and mechanical stress during start-up, improving motor lifetime, and easing load on electrical installation. The unit supports small-to-medium motors, making it suitable for pumps, fans, conveyors and general-purpose industrial loads where gentle motor start-up is desired.\n\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSIRIUS 3RW40 soft-starter, size S0\u003c\/li\u003e\n  \u003cli\u003eRated operational current: 12.5 A (at 40 °C)\u003c\/li\u003e\n  \u003cli\u003eRated motor power (400 V): up to 5.5 kW\u003c\/li\u003e\n  \u003cli\u003eMain supply voltage range: 200–480 V AC, 3-phase\u003c\/li\u003e\n  \u003cli\u003eControl supply voltage: 24 V AC\/DC\u003c\/li\u003e\n  \u003cli\u003eIntegrated bypass contact system — reduces heat losses after start-up\u003c\/li\u003e\n  \u003cli\u003eThyristor-based starting control with adjustable current limitation\u003c\/li\u003e\n  \u003cli\u003eScrew-terminal connections for main and control wiring\u003c\/li\u003e\n  \u003cli\u003eProvides motor overload protection and intrinsic device protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArticle Number:\u003c\/strong\u003e 3RW4024-1BB04\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Soft-starter, SIRIUS 3RW40, size S0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperational Current (Ie at 40 °C):\u003c\/strong\u003e 12.5 A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Output Power (400 V):\u003c\/strong\u003e 5.5 kW\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSupply Voltage (Motor):\u003c\/strong\u003e 200–480 V AC, 3-phase\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Voltage:\u003c\/strong\u003e 24 V AC\/DC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThyristor Blocking Voltage:\u003c\/strong\u003e 1,600 V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRated Insulation Voltage (Ui):\u003c\/strong\u003e 600 V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDegree of Pollution:\u003c\/strong\u003e 3 (according to IEC 60947-4-2)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProtection Class \/ Connection Type:\u003c\/strong\u003e Screw terminals\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFeatures:\u003c\/strong\u003e Integrated bypass contact, adjustable current limitation, motor overload protection\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTypical Use Case:\u003c\/strong\u003e Soft-starting three-phase motors up to ~5.5 kW, especially for smaller loads\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e\u003cstrong\u003eCompliance \u0026amp; Standards\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned under SIRIUS 3RW soft-starter standard product line — ensures compatibility with industrial motor-starting norms\u003c\/li\u003e\n  \u003cli\u003eMeets requirements for electrical insulation and pollution degree per IEC 60947-4-2\u003c\/li\u003e\n  \u003cli\u003eThyristor switching and bypass contact system compliant with motor-starter safety and performance standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e\u003cstrong\u003eApplications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\nThe 3RW4024-1BB04 soft-starter is suited for small to medium three-phase motors in industrial installations, e.g. pumps, fans, small conveyors, mixers or light machinery.
