This sophisticated three-phase relay combines overcurrent and earth-fault detection features in a compact unit, making it ideal for a variety of applications in industrial plants, utility networks, and commercial power systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFunctional Highlights\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe SPAJ144C-AA offers dual-stage phase protection, which includes low-set (definite time or IDMT) and high-set (instantaneous or definite time) units for precise fault detection. In addition to these, the relay’s earth-fault protection stages enhance its capability to respond effectively to electrical faults. The relay also incorporates built-in circuit-breaker failure protection and features two heavy-duty plus four configurable signal output relays, all of which can be routed through an output relay matrix for optimal flexibility.\u003c\/p\u003e\n\u003cp\u003eMoreover, this relay is designed for radial feeder protection, proving effective in various earthing systems, including solidly earthed and resistance or impedance earthed systems. Its advanced monitoring capabilities display measured values, fault records, and setting parameters through an intuitive local display, as well as remotely via a serial interface.\u003c\/p\u003e\n\u003cp\u003eThe SPAJ144C-AA is equipped with robust self-supervision systems that continuously monitor microprocessor operation and electronics health. With powerful configuration software, this relay enables in-depth parameterization, data recording, and event logging. Its compatibility with fiber-optic buses enhances its integration into modern automated substations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Data\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSPAJ144C-AA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModule Type:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eCombined Overcurrent and Earth-Fault Relay\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eABB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eBrand New\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e3.36 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e14 x 25 x 16 cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHS CODE:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e8537101190\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Origin:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSweden\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Time:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIn Stock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity (MOQ):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Voltage:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e48-250 V AC\/DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelay Outputs:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e2 heavy-duty and 4 configurable signal outputs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResponse Times:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eConfigurable for rapid fault isolation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnvironmental Compliance:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eCE certified for EMC\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTypical Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe ABB SPAJ144C-AA is suitable for:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIndustrial plants requiring reliable protection of feeders and motors.\u003c\/li\u003e\n\u003cli\u003eUtility networks seeking advanced monitoring and control capabilities.\u003c\/li\u003e\n\u003cli\u003eCommercial power systems needing high-performance and adaptable protection solutions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFAQ\u003c\/strong\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the weight of the SPAJ144C-AA Relay?\u003c\/strong\u003e\u003cbr\u003eThe SPAJ144C-AA weighs 3.36 kg.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the SPAJ144C-AA?\u003c\/strong\u003e\u003cbr\u003eIts dimensions are 14 x 25 x 16 cm.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhat voltage range can the SPAJ144C-AA operate within?\u003c\/strong\u003e\u003cbr\u003eThe relay operates within a voltage range of 48-250 V AC\/DC.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eHow many output relays does the SPAJ144C-AA have?\u003c\/strong\u003e\u003cbr\u003eIt features two heavy-duty and four signal output relays.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eIs the SPAJ144C-AA suitable for modern automated substations?\u003c\/strong\u003e\u003cbr\u003eYes, its compatibility with fiber-optic buses makes it ideal for automated substations.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":53262984970550,"sku":"SPAJ144C-AA","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/2094\/8534\/files\/abb-spaj144c-aa-combined-overcurrent-and-earth-fault-relay-dw3cc3imoaa.jpg?v=1762918214","url":"https:\/\/www.motrolixtech.com\/products\/abb-spaj144c-aa-combined-overcurrent-and-earth-fault-relay","provider":"Motrolix","version":"1.0","type":"link"}
