This integrated protective relay connects to current transformers (CTs) to measure earth-fault currents using both residual current (three-phase CTs) and core-balance CT methods. By triggering alarms, tripping circuit breakers, or initiating auto-reclose functions, the SPAJ 110 C-AA ensures optimal protection for your electrical systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFunctional Highlights\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis Earth-fault relay features adjustable low-set (Io\u0026gt;) and high-set (Io\u0026gt;\u0026gt;) stages, allowing for precise tailoring to specific operational requirements. Users can choose between definite-time (DT) or inverse-time (IDMT) operation, with the IDMT mode offering four standardized curves—Normal, Very, Extremely, and Long-time Inverse—complying with IEC 255 and BS 142 standards.\u003c\/p\u003e\n\u003cp\u003eMoreover, the SPAJ 110 C-AA includes a start signal contact function for coordination with other relays, enhancing the overall efficiency of the system. An optical logic input enables external blocking signals, further increasing integration capabilities with existing protection systems.\u003c\/p\u003e\n\u003cp\u003eTo maximize reliability, this integrated protective relay features an auto-diagnostic system that continuously monitors all hardware, software, and auxiliary power. Upon detecting a fault, the relay activates an output relay, illuminates an IRF indicator, and displays a fault code via serial communication. This self-supervision capability significantly reduces downtime and enhances system availability.\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\u003eSPAJ 110 C-AA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModule Type:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIntegrated Protective 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\u003e3.2 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e24 x 13.2 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\u003eMeasurement Methods:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eResidual current and core-balance CT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Modes:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eLow-set (Io\u0026gt;) and high-set (Io\u0026gt;\u0026gt;) stages\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompliance:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIEC 255, BS 142\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommunication Service:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eEthernet router\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTypical Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe ABB SPAJ 110 C-AA Earth-fault Relay is ideal for:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSubstations and industrial networks requiring enhanced earth-fault protection.\u003c\/li\u003e\n\u003cli\u003eIntegration into electrical protection systems where precise settings and diagnostics are crucial.\u003c\/li\u003e\n\u003cli\u003eModern power systems focusing on reliability and compliance with international safety standards.\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 SPAJ 110 C-AA Earth-fault Relay?\u003c\/strong\u003e\u003cbr\u003eThe SPAJ 110 C-AA weighs 3.2 kg.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the SPAJ 110 C-AA?\u003c\/strong\u003e\u003cbr\u003eIts dimensions are 24 x 13.2 x 16 cm.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhat communication services does the SPAJ 110 C-AA support?\u003c\/strong\u003e\u003cbr\u003eIt includes an Ethernet router for communication services.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhat operation modes does the relay offer?\u003c\/strong\u003e\u003cbr\u003eThe relay features low-set and high-set stages with definite-time or inverse-time operation.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eIs the SPAJ 110 C-AA compliant with international standards?\u003c\/strong\u003e\u003cbr\u003eYes, it complies with IEC 255 and BS 142.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":53262988509494,"sku":"SPAJ","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/2094\/8534\/files\/abb-spaj-110-c-aa-earth-fault-relay-np1dgr4fmro.jpg?v=1762918266","url":"https:\/\/www.motrolixtech.com\/products\/abb-spaj-110-c-aa-earth-fault-relay","provider":"Motrolix","version":"1.0","type":"link"}
