This relay provides reliable overload and phase failure protection for motors, featuring adjustable current settings and Class 10 tripping characteristics. The 3RU1146-4JB0 is compatible with Siemens 3RT1044, 3RT1045, and 3RT1046 contactors and mounts directly to these devices. It offers both manual and automatic reset options, a test function for verifying operation, and a stop button for emergency shutdown. The relay includes a sealable cover and provides switching position indication for easy monitoring. The main and auxiliary circuits use screw terminals for secure connections. \u003cul\u003e \u003cli\u003eAdjustable current range: 45-63 A\u003c\/li\u003e \u003cli\u003eClass 10 tripping characteristic\u003c\/li\u003e \u003cli\u003eManual and automatic reset\u003c\/li\u003e \u003cli\u003eTest and stop functions\u003c\/li\u003e \u003cli\u003eMounts to 3RT1044, 3RT1045, 3RT1046 contactors\u003c\/li\u003e \u003cli\u003ePhase failure sensitivity\u003c\/li\u003e \u003cli\u003eSwitching position indication\u003c\/li\u003e \u003cli\u003eSealable cover\u003c\/li\u003e \u003cli\u003e1 NO + 1 NC auxiliary contacts\u003c\/li\u003e \u003cli\u003eScrew terminal connections\u003c\/li\u003e \u003cli\u003eMotor protection for three-phase loads\u003c\/li\u003e \u003cli\u003eSize S3 frame\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: 3RU1146-4JB0\u003c\/li\u003e                                             \u003cli\u003eManufacturer : Siemens\u003c\/li\u003e\n\u003cli\u003eBrand : Siemens\u003c\/li\u003e\n\u003cli\u003eCategory : Motor Control\u003c\/li\u003e\n\u003cli\u003eItem Subcategory : Overload Relay\u003c\/li\u003e\n\u003cli\u003eRelay Style : Thermal\u003c\/li\u003e\n\u003cli\u003eAmperage Maximum : 63\u003c\/li\u003e\n\u003cli\u003eAmperage Minimum : 45\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 : 075455441257\u003c\/li\u003e\n\u003cli\u003eGTIN : 00754554412573\u003c\/li\u003e\n\u003cli\u003eWeight : 1.232 \u003c\/li\u003e\n\u003c\/ul\u003e                                         \u003cbr\u003e                                          ","brand":"Siemens","offers":[{"title":"New","offer_id":42910835638431,"sku":"3RU1146-4JB0-New","price":209.24,"currency_code":"USD","in_stock":true},{"title":"Re-Certified","offer_id":45169036427423,"sku":"3RU1146-4JB0-ReCert","price":117.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0500\/2349\/7887\/files\/3RU1146-4JB0.jpg?v=1760681041","url":"https:\/\/essentialparts.com\/products\/3ru1146-4jb0-siemens-45-63a-thermal-magnetic-overload-relay-for-motor-protection-size-s3-class-10","provider":"Essential Electric Supply","version":"1.0","type":"link"}
