The hardware component controls main power circuits by actuating three main 1 NO\/1 NC auxiliary contacts via an electromagnetic operating coil. Designed for direct mounting on industrial panels, it provides physical contact separation to execute start, stop, and reversing sequences across connected inductive and resistive loads.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eA50-30-11 (1SBL351001R8011)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eABB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eFrance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.16 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e108 x 70 x 110 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-40 deg C to +70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eCoil Holding 18 VA \/ Inrush 180 VA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eContactors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMain Contacts\u003c\/td\u003e\n\u003ctd\u003e3 NO\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAuxiliary Contacts\u003c\/td\u003e\n\u003ctd\u003e1 NO + 1 NC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Operational Current\u003c\/td\u003e\n\u003ctd\u003e50 A (AC-3), 100 A (AC-1)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCoil Voltage\u003c\/td\u003e\n\u003ctd\u003e220-230 VAC 50Hz \/ 230-240 VAC 60Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eBackplane Bus Communication Velocity \u0026amp; I\/O Density Scaling\u003c\/h3\u003e\n\u003cp\u003eWhen deployed alongside PLC-driven motor control centers, the contactor interface operates via interposing relay channels to decouple switching transients from backplane bus communication structures. Digital output modules trigger coil energization, requiring deterministic I\/O scan execution to preserve system timing. Proper I\/O density scaling inside control enclosures demands adherence to spacing intervals to prevent cumulative thermal load buildup across adjacent switching devices.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What precautions should be taken regarding coil voltage tolerances during continuous operation?\u003c\/p\u003e\n\u003cp\u003eA: The AC control coil must be supplied within 85% to 110% of its rated operational voltage (220-240 VAC). Undervoltage conditions can lead to contact chatter and excessive arc erosion, while sustained overvoltage increases thermal coil stress.\u003c\/p\u003e\n\u003cp\u003eQ: Can auxiliary contact blocks be expanded on the A50-30-11 chassis?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the contactor chassis supports side-mounted and front-mounted auxiliary contact blocks to scale status feedback signals into high-density PLC digital input cards.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eMount the unit vertically on a rigid panel or standard mounting rail using designated screw fasteners to maintain mechanical alignment.\u003c\/li\u003e\n\u003cli\u003eVerify all power and auxiliary terminal screws are torqued to specified manufacturer limits to prevent high-resistance terminal hot spots.\u003c\/li\u003e\n\u003cli\u003eMaintain recommended physical clearance distances above and below the arc chute vents to allow adequate arc gas dissipation.\u003c\/li\u003e\n\u003cli\u003eSeparate high-voltage AC load wiring from low-voltage signal cables in wire ducts to suppress inductive noise coupling.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":45401613533299,"sku":"A50-30-11 1SBL351001R8011","price":233.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/PM590.jpg?v=1787732868","url":"https:\/\/www.dcssupplier.com\/products\/abb-a50-30-11-1sbl351001r8011-contactors","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
