Designed for use as a secondary relay with current transformers, the SPAJ140C continuously monitors both phase and neutral currents. Upon detection of unsafe conditions, it can trigger circuit breaker tripping, initiate auto-reclosing, sound alarms, and record faults, ensuring robust protection of electrical systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFunctional Highlights\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEngineered for reliability, the SPAJ140C features low-set stages (I\u0026gt; and I0\u0026gt;) that activate within approximately 60 ms, while high-set stages (I\u0026gt;\u0026gt; and I0\u0026gt;\u0026gt;) respond even more quickly at around 40 ms, facilitating rapid fault isolation. This quick response minimizes potential damage and system downtime.\u003c\/p\u003e\n\u003cp\u003eMoreover, the relay provides flexible time-current characteristics with options for either definite time or inverse definite minimum time (IDMT) operation for both overcurrent and earth-fault detection. It offers six curve options, including four standardized curves (Normal, Very, Extremely, and Long-time inverse per BS 142\/IEC 60255) in addition to specialized curves RI and RXIDG, allowing personalized coordination with other protective devices in diverse power systems.\u003c\/p\u003e\n\u003cp\u003eConfigurable output relays enable the SPAJ140C to deliver start signals for blocking co-protection relays and facilitate alarm signaling or auto-reclosing initiation. Additionally, an integrated binary input supports remote control functions, including stage blocking, manual resetting of latched relays, and dynamic setting group changes—enhancing adaptability within the system.\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\u003eSPAJ140C\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\u003e3.2 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\u003eOperating Voltage Range:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e48-250 V AC\/DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResponse Times:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eLow-set stages (I\u0026gt; and I0\u0026gt;): ~60 ms\u003c\/li\u003e\n\u003cli\u003eHigh-set stages (I\u0026gt;\u0026gt; and I0\u0026gt;\u0026gt;): ~40 ms\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Relay Rating:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e5A at 250V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e-25°C to +55°C\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTypical Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe ABB SPAJ140C is ideal for:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFeeder and motor protection in industrial power systems.\u003c\/li\u003e\n\u003cli\u003eUtility substations requiring intricate coordination for enhanced protection.\u003c\/li\u003e\n\u003cli\u003eCommercial electrical distribution systems where rapid response and reliable operation are critical.\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 SPAJ140C Relay?\u003c\/strong\u003e\u003cbr\u003eThe SPAJ140C weighs 3.2 kg.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the SPAJ140C?\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 voltage range can the SPAJ140C operate within?\u003c\/strong\u003e\u003cbr\u003eIt functions within a voltage range of 48-250V AC\/DC.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eHow quickly can the SPAJ140C respond to current faults?\u003c\/strong\u003e\u003cbr\u003eLow-set stages respond in approximately 60 ms, while high-set stages respond in 40 ms.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhat features enhance the flexibility of the SPAJ140C?\u003c\/strong\u003e\u003cbr\u003eIt offers configurable output relays and an integrated binary input for remote control functions.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":53262987886902,"sku":"SPAJ140C","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/2094\/8534\/files\/abb-spaj140c-combined-overcurrentand-earth-fault-relay-cb3vlebh1qy.jpg?v=1762918261","url":"https:\/\/www.motrolixtech.com\/products\/abb-spaj140c-combined-overcurrent-and-earth-fault-relay","provider":"Motrolix","version":"1.0","type":"link"}
