This 3-pole device features manual\/automatic reset, screw terminals for both main and auxiliary circuits, and is compatible with contactor mounting for easy integration into motor control systems. The relay provides precise overload protection for motors with a full-load current range of 36 to 50 amps and is suitable for use in 3-phase systems. Engineered for durability and safety, the 3RU21464HB0 offers a switching voltage up to 690 VAC, IP20 protection on the front, and robust thermal overload protection with Class 10 trip characteristics. The relay includes one normally open (NO) and one normally closed (NC) auxiliary contact for control circuit signaling. Its compact S3 frame design and versatile mounting options make it ideal for a wide range of motor control panels and industrial environments. \u003cul\u003e \u003cli\u003ePart Number: 3RU21464HB0\u003c\/li\u003e \u003cli\u003eManufacturer: Siemens\u003c\/li\u003e \u003cli\u003eSeries\/Frame: SIRIUS S3\u003c\/li\u003e \u003cli\u003eAmperage Range: 36-50 A\u003c\/li\u003e \u003cli\u003eNumber of Poles: 3\u003c\/li\u003e \u003cli\u003eMounting Type: Contactor Mounting\u003c\/li\u003e \u003cli\u003eTerminal Type: Screw\u003c\/li\u003e \u003cli\u003eSwitching Voltage: 690 VAC\u003c\/li\u003e \u003cli\u003eProtection Class: IP20\u003c\/li\u003e \u003cli\u003eTrip Class: Class 10\u003c\/li\u003e \u003cli\u003eReset Type: Manual\/Automatic\u003c\/li\u003e \u003cli\u003eAuxiliary Contact: 1NO\/1NC\u003c\/li\u003e \u003c\/ul\u003e At \u003cb\u003eEssential Parts\u003c\/b\u003e, we offer \u003cb\u003efast shipping\u003c\/b\u003e, \u003cb\u003elowest price\u003c\/b\u003e, and \u003cb\u003eexpert support\u003c\/b\u003e to help you get the right product every time. \t\t\t\t\t\t\t\t\t\t\u003cbr\u003e                                          \t\t\t\t\t\t\t\t\t\t\u003ch3\u003e\u003cb\u003eSpecifications\u003c\/b\u003e\u003c\/h3\u003e \t\t\t\t\t\t\t\t\t\t\u003cul\u003e \t\t\t\t\t\t\t\t\t\t\t\u003cli\u003ePart Number: 3RU21464HB0\u003c\/li\u003e                                             \u003cli\u003eBrand : Siemens\u003c\/li\u003e\n\u003cli\u003eCategory : Motor Control\u003c\/li\u003e\n\u003cli\u003eItem Subcategory : Contactors\u003c\/li\u003e\n\u003cli\u003eSection  : Overload relay\u003c\/li\u003e \t\t\t\t\t\t\t\t\t\t\u003c\/ul\u003e                                         \u003cbr\u003e                                         \u003ch3\u003e\u003cb\u003eProduct Data\u003c\/b\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eUPC : 804766359354\u003c\/li\u003e\n\u003cli\u003eCountry of Origin : Germany\u003c\/li\u003e\n\u003cli\u003eDimensions : 5.118 x 3.071 x 4.488 inch\u003c\/li\u003e\n\u003cli\u003eWeight : 1.199 lb\u003c\/li\u003e\n\u003c\/ul\u003e                                         \u003cbr\u003e                                          ","brand":"Siemens","offers":[{"title":"New","offer_id":46757258199199,"sku":"3RU21464HB0-New","price":297.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0500\/2349\/7887\/files\/3RU21464HB0.jpg?v=1760715565","url":"https:\/\/essentialparts.com\/products\/3ru21464hb0","provider":"Essential Electric Supply","version":"1.0","type":"link"}
