It is the part that actually acts: on a short circuit or a sustained overload it melts and opens the circuit, keeping cables, batteries and inverter out of trouble.\u003c\/p\u003e\n \u003cp\u003eSize is \u003cstrong\u003eNH1\u003c\/strong\u003e and rated current \u003cstrong\u003e250A\u003c\/strong\u003e, with a \u003cstrong\u003egG\u003c\/strong\u003e operating class — the general-purpose curve that rides out the normal inrush of a storage system and clears real faults. Jean Müller rates it at \u003cstrong\u003eAC 500V\u003c\/strong\u003e with a \u003cstrong\u003e120kA\u003c\/strong\u003e breaking capacity, 21,6W power dissipation at rated current and a combi indicator, so you can see at a glance which link has gone.\u003c\/p\u003e\n \u003cp\u003eOne point that matters when sizing a DC circuit: \u003cstrong\u003eJean Müller declares no rated DC voltage for gG fuse links\u003c\/strong\u003e. The catalogue rates them for AC only and, for DC applications, lists a separate family of special-purpose types rated from DC80V to DC440V. The DC figures given below, 250V DC per pole and up to 440V DC with the poles in series, are limits of the KETO 1 switch and not a rated voltage of the link itself: suitability for DC has to be assessed on the holder-plus-link assembly, or by choosing a link that is declared for DC.\u003c\/p\u003e\n \u003cp\u003eThe KETO-1 switch takes \u003cstrong\u003etwo links\u003c\/strong\u003e, one on the positive pole and one on the negative, so a complete install needs a pair. Size them on the battery’s maximum charge and discharge current with a safety margin, not on the inverter’s rated current. Fitting is a job for a qualified electrician, to local wiring rules.\u003c\/p\u003e\n \u003ch3\u003eKey strengths\u003c\/h3\u003e\n \u003cdiv class=\"cs\"\u003e\n  \u003cdiv class=\"c\"\u003e \u003cb\u003eNH1 size, 250A\u003c\/b\u003e\u003cspan\u003eBlade-contact link for the Jean Müller KETO-1 switch.\u003c\/span\u003e \u003c\/div\u003e\n  \u003cdiv class=\"c\"\u003e \u003cb\u003egG class\u003c\/b\u003e\u003cspan\u003eGeneral purpose: rides out inrush, clears faults.\u003c\/span\u003e \u003c\/div\u003e\n  \u003cdiv class=\"c\"\u003e \u003cb\u003e120kA breaking capacity\u003c\/b\u003e\u003cspan\u003eFigure declared by Jean Müller for this range.\u003c\/span\u003e \u003c\/div\u003e\n  \u003cdiv class=\"c\"\u003e \u003cb\u003eCombi indicator\u003c\/b\u003e\u003cspan\u003eTells you from the front which link has blown.\u003c\/span\u003e \u003c\/div\u003e\n  \u003cdiv class=\"c\"\u003e \u003cb\u003eTwo needed\u003c\/b\u003e\u003cspan\u003eOne on the positive pole and one on the negative.\u003c\/span\u003e \u003c\/div\u003e\n \u003c\/div\u003e\n \u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n \u003cdiv class=\"tw\"\u003e\u003ctable\u003e \u003cthead\u003e\u003ctr\u003e \u003cth\u003eFeature\u003c\/th\u003e \u003cth\u003eValue\u003c\/th\u003e \u003c\/tr\u003e\u003c\/thead\u003e \u003ctbody\u003e\n  \u003ctr\u003e \u003ctd\u003eProduct code\u003c\/td\u003e \u003ctd\u003eN1015605-250A\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eJean Müller article no.\u003c\/td\u003e \u003ctd\u003eN1015605\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eCatalogue designation\u003c\/td\u003e \u003ctd\u003eM1GL250\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eManufacturer\u003c\/td\u003e \u003ctd\u003eJean Müller\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eType\u003c\/td\u003e \u003ctd\u003eNH blade-contact fuse link\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eNH size\u003c\/td\u003e \u003ctd\u003eNH1\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eRated current\u003c\/td\u003e \u003ctd\u003e250A\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eOperating class\u003c\/td\u003e \u003ctd\u003egG (general purpose, formerly gL)\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eRated voltage\u003c\/td\u003e \u003ctd\u003eAC 500V (Jean Müller data)\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eRated DC voltage of the link\u003c\/td\u003e \u003ctd\u003eNot declared: Jean Müller rates gG links for AC only and lists dedicated special-purpose types, from DC80V to DC440V, for DC applications\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eDC voltage\u003c\/td\u003e \u003ctd\u003e250V DC per pole, up to 440V DC with the poles in series (Jean Müller data)\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eBreaking capacity\u003c\/td\u003e \u003ctd\u003e120kA (Jean Müller data)\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003ePower dissipation at rated current\u003c\/td\u003e \u003ctd\u003e21,6W (Jean Müller data)\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eBlown-fuse indicator\u003c\/td\u003e \u003ctd\u003ecombi indicator, visible from the front\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eMatching fuse holder\u003c\/td\u003e \u003ctd\u003eJean Müller KETO-1 switch-disconnector\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eStandards\u003c\/td\u003e \u003ctd\u003eIEC\/EN 60269-1, DIN VDE 0636-2\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eWeight\u003c\/td\u003e \u003ctd\u003e0,42kg\u003c\/td\u003e \u003c\/tr\u003e\n  \u003ctr\u003e \u003ctd\u003eSource of the technical data\u003c\/td\u003e \u003ctd\u003eFigures declared by Jean Müller, NH fuse-link catalogue\u003c\/td\u003e \u003c\/tr\u003e\n \u003c\/tbody\u003e \u003c\/table\u003e\u003c\/div\u003e\n \u003ca class=\"d\" href=\"https:\/\/samonolithportalprodcdn.blob.core.windows.net\/assets\/general_product_documents\/e20f1c12851c537b08bf49bf2932885969ac0b0e_Jean_Muller_Data_sheet_.pdf\" target=\"_blank\" rel=\"noopener\"\u003e\u003ci\u003ePDF\u003c\/i\u003e\u003cspan\u003eManufacturer datasheet\u003csmall\u003ePDF document\u003c\/small\u003e\u003c\/span\u003e\u003c\/a\u003e\n\u003c\/div\u003e","brand":"Jean Müller","offers":[{"title":"Default Title","offer_id":55354485866833,"sku":"N1015605-250A","price":8.07,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2510\/0896\/files\/N1015605-250A.jpg?v=1792283648","url":"https:\/\/litio.store\/en\/products\/fusibile-nh1-jean-muller-m1gl250-250a-gg-500v-per-sezionatore-keto-1","provider":"litio.store","version":"1.0","type":"link"}
