It gives overcurrent protection on heavy-duty DC circuits such as inverter feeds, battery interconnects and busbar connections.\u003c\/p\u003e\u003ch2\u003eMega fuse features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent rating\u003c\/strong\u003e, 250A continuous, for overcurrent protection on heavy-duty DC circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage rating\u003c\/strong\u003e, 80V DC, compatible with 12V, 24V and 48V battery systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat\u003c\/strong\u003e, MEGA blade fuse, fits standard MEGA fuseholders including Victron's own range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack quantity\u003c\/strong\u003e, 5 fuses per pack.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e, 45g per pack.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct overview\u003c\/h2\u003e\u003cp\u003eMEGA fuses are widely used where high current flows between batteries and inverters or charge controllers. The 250A rating suits inverter installations in the 2kW to 5kW range on 12V or 24V systems, protecting cable runs from the battery bank against short-circuit faults. At 80V DC, the rating sits above the maximum operating voltage of a 48V battery system.\u003c\/p\u003e\u003cp\u003eThe MEGA format uses a bolt-down or clip-in fuseholder rather than a plug-in blade, making it better suited to high-current applications than standard automotive blade fuses. A compatible MEGA fuseholder is required and sold separately. Check that the fuseholder's current and voltage ratings match or exceed those of the fuse before fitting it.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOvercurrent protection on inverter DC input cables in 12V and 24V off-grid systems.\u003c\/li\u003e\n\u003cli\u003eBattery bank to busbar connections in marine, motorhome and vehicle installations.\u003c\/li\u003e\n\u003cli\u003eDC distribution boards in off-grid cabins, narrowboats and remote power systems.\u003c\/li\u003e\n\u003cli\u003eReplacement fuses for existing MEGA fuseholder installations.\u003c\/li\u003e\n\u003cli\u003eMulti-circuit DC systems where several high-current feeds need individual fuse protection.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e5 x Victron Energy MEGA-fuse 250A\/80V\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eInstallation notes\u003c\/h2\u003e\u003cp\u003eFit the fuse in a compatible MEGA fuseholder rated for the circuit's voltage and current, positioned as close to the positive battery terminal as practicable so the full cable run is protected. Wiring at these current levels carries significant fault energy, so connections should be made by a qualified electrician or competent installer familiar with DC battery systems. Confirm the cable cross-section is sized correctly for 250A continuous current before choosing this fuse rating.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":52060311585056,"sku":"CIP138250020","price":26.23,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1010\/8148\/1504\/files\/ledandsolar-cip138250020-1.webp?v=1785487950","url":"https:\/\/www.ledandsolar.co.uk\/products\/victron-mega-fuse-250a-pack-of-5","provider":"LED \u0026 Solar","version":"1.0","type":"link"}
