Deve essere collegato in serie con il fusibile di backup XRNT-15.5 per la protezione da cortocircuito di trasformatori immersi in olio per formare la protezione da sovraccarico e cortocircuito per trasformatori di potenza. Nello specifico, viene utilizzato solo per proteggere da guasti di cortocircuito sul lato secondario dei trasformatori e da correnti di guasto entro un intervallo ristretto come parte della fornitura di protezione a tutto campo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dimensioni d'ingombro e di montaggio (mm)<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"735\" height=\"267\" src=\"https:\/\/yieou.com\/wp-content\/uploads\/2026\/01\/cbdaad09-e81a-44d4-9e25-86bc8ef86f26.png\" alt=\"\" class=\"wp-image-1196\" srcset=\"https:\/\/yieou.com\/wp-content\/uploads\/2026\/01\/cbdaad09-e81a-44d4-9e25-86bc8ef86f26.png 735w, https:\/\/yieou.com\/wp-content\/uploads\/2026\/01\/cbdaad09-e81a-44d4-9e25-86bc8ef86f26-300x109.png 300w\" sizes=\"(max-width: 735px) 100vw, 735px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>Tensione Nominale (kV)<\/td><td>Tensione max.
