It is designed for switching three-phase AC motors and other industrial loads, combining compact dimensions with reliable switching capacity. With a 7.5 kW motor power rating (at 400 V) and 16 A contact current, it is suitable for small motors and general AC load applications. The device includes a single auxiliary contact (1 NC) and uses screw-type terminals for secure wiring. Its compact size and strong switching performance make it well suited for control cabinets, motor starters, and automation systems.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSIRIUS 3RT2 series, size S00, 3-pole power contactor\u003c\/li\u003e\n\u003cli\u003eMain contact rating: 16 A, 400 V AC\u003c\/li\u003e\n\u003cli\u003eMotor power rating (AC-3, 400 V): 7.5 kW\u003c\/li\u003e\n\u003cli\u003eSingle auxiliary contact: 1 NC — useful for interlocks, signalling or control logic\u003c\/li\u003e\n\u003cli\u003eScrew-type main and auxiliary terminals — secure wiring suitable for industrial environments\u003c\/li\u003e\n\u003cli\u003eCompact dimensions: width 45 mm — fits small control panels \/ motor starters\u003c\/li\u003e\n\u003cli\u003eStandard 3-pole config — compatible with three-phase motors and load circuits\u003c\/li\u003e\n\u003cli\u003eCompliant with SIRIUS \/ IEC contactor standards for safe and reliable switching in industrial systems\u003c\/li\u003e\n\u003c\/ul\u003e\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 3RT2018-1BB42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContactor Size:\u003c\/strong\u003e S00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles (main contacts):\u003c\/strong\u003e 3 (three-phase switching)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuxiliary Contacts:\u003c\/strong\u003e 1 NC (normally closed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMain Contact Rating:\u003c\/strong\u003e 16 A, 400 V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Power Rating (AC-3, 400 V):\u003c\/strong\u003e 7.5 kW\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Type:\u003c\/strong\u003e Screw terminals for main and auxiliary circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting \/ Housing:\u003c\/strong\u003e Standard DIN-rail \/ control-cabinet compatible (size S00 compact housing)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntended Use:\u003c\/strong\u003e Switching three-phase motors or AC loads, motor-starter applications, general load control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eCompliance \u0026amp; Standards\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePart of Siemens SIRIUS 3RT2 contactor family — global standard for industrial switching devices\u003c\/li\u003e\n\u003cli\u003eDesigned for AC-3 motor switching applications; meets relevant IEC\/EN contactor standards\u003c\/li\u003e\n\u003cli\u003eSuitable for industrial control cabinets, motor feeders and automation systems requiring compact and reliable contactors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eApplications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThis contactor is ideal for controlling small to medium three-phase motors (e.g. pumps, fans, small compressors), lighting or general AC load circuits where up to 7.5 kW \/ 16 A switching is adequate.
