DIAZED fuses are a standardized European-origin cartridge fuse format widely used in industrial control panels, switchgear, and power distribution equipment. This fuse provides reliable short-circuit and overload protection where a compact, size-specific fusible element is required. It is installed by licensed electricians and industrial maintenance technicians working on low-voltage distribution panels and control circuits. The package contains one fuse per pack.\u003c\/p\u003e\n\u003cp\u003eThe 5SB251 is suited for use in industrial and commercial electrical systems that specify DIAZED-format fuse holders. Typical installations include motor control centers, distribution boards, and industrial control panels where standardized fuse sizing and form factor are critical to maintaining system protection coordination. This fuse format is common in facilities with European-specification equipment or legacy switchgear that requires DIAZED-compatible components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDIAZED cartridge fuse format for standardized overcurrent protection\u003c\/li\u003e\n  \u003cli\u003eCompact form factor fits DIAZED-compatible fuse holders and bases\u003c\/li\u003e\n  \u003cli\u003eSingle fuse per pack for precise quantity control on service calls\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.060 pounds for easy handling and transport\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for DIAZED-format fuse holders used in low-voltage industrial and commercial electrical distribution panels.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit using proper LOTO procedures before removing or installing any fuse. Verify that the replacement fuse matches the required current rating, voltage rating, and DIAZED size designation of the existing fuse before installation. Do not install a fuse with a higher current rating than the circuit is designed to carry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: DIAZED\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4.370 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.984 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.008 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.060 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 75455421449\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SIEMENS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5SB251\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383275979058,"sku":"5SB251","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312676871.jpg?v=1782591909","url":"https:\/\/voomisupply.com\/products\/siemens-5sb251-diazed-fuse-1-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
