It is designed for switching AC loads with electronic control, offering a compact, reliable, maintenance-free alternative to electromechanical contactors. Suitable for resistive or lightly inductive loads, it supports AC 51 duty up to 30 A at 48–460 V AC (50\/60 Hz), with control supply 4–30 V DC. Its design ensures short-circuit safety when used with appropriate upstream protection devices.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid-state contactor — SIRIUS 3RF2 series (1-phase)\u003c\/li\u003e\n  \u003cli\u003eAC load switching: 48–460 V AC, 30 A (AC-51), ideal for resistive or low-inductive loads\u003c\/li\u003e\n  \u003cli\u003eControl input: 4–30 V DC control voltage\u003c\/li\u003e\n  \u003cli\u003eShort-circuit safe when protected by B-type miniature circuit breaker (MCB)\u003c\/li\u003e\n  \u003cli\u003eCompact single-pole format — space-efficient for control panels or switchgear\u003c\/li\u003e\n  \u003cli\u003eLow maintenance, long operational life — no mechanical contacts, silent switching\u003c\/li\u003e\n  \u003cli\u003eInsulation voltage: 600 V; surge resistance: 6 kV; protection class IP20\u003c\/li\u003e\n  \u003cli\u003eShock resistance and vibration tolerance per industrial standards\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 3RF2330-1DA44\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Solid-state contactor (single-phase \/ 1-pole)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMain Circuit Voltage Range:\u003c\/strong\u003e 48 … 460 V AC, 50\/60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRated Operational Current (AC-51):\u003c\/strong\u003e 30 A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Voltage (DC):\u003c\/strong\u003e 4 … 30 V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Control Voltage:\u003c\/strong\u003e 4 V DC (ON detection threshold)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Voltage:\u003c\/strong\u003e 600 V AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSurge Voltage Withstand:\u003c\/strong\u003e 6 kV\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProtection Rating:\u003c\/strong\u003e IP20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperational Conditions:\u003c\/strong\u003e Rated for 40 °C ambient temperature without derating\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Loss (at rated current):\u003c\/strong\u003e 33 W (hot state)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Poles:\u003c\/strong\u003e 1 (single-phase switching)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNO Contacts (main):\u003c\/strong\u003e 1 (solid-state switching element)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLoad Types:\u003c\/strong\u003e Resistive and low-inductive (e.g. heaters, lighting, resistive loads)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting \/ Terminals:\u003c\/strong\u003e Screw-terminal connections; typical PCB or DIN-rail \/ panel mount compatible when in enclosure\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\u003eBelongs to Siemens SIRIUS 3RF2 solid-state contactor family\u003c\/li\u003e\n  \u003cli\u003eShort-circuit resistant configuration when used with B-type MCB per specification\u003c\/li\u003e\n  \u003cli\u003eRated for industrial shock, surge and pollution class 3 environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e\u003cstrong\u003eApplications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eIdeal for switching resistive or lightly inductive AC loads — such as heaters, lighting circuits, resistive loads, or control circuits — especially where silent, maintenance-free switching is required.
