Sold in a pack of five, it is suited to professional installers who need reliable overcurrent protection at 400A continuous rating with an 80V DC voltage rating.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e400A continuous current rating for high-load DC circuits.\u003c\/li\u003e\n  \u003cli\u003e80V DC voltage rating, compatible with 12V, 24V and 48V battery systems.\u003c\/li\u003e\n  \u003cli\u003eMEGA blade fuse format, compatible with standard MEGA fuseholders.\u003c\/li\u003e\n  \u003cli\u003ePack of 5 fuses, providing spares for commissioning and ongoing maintenance.\u003c\/li\u003e\n  \u003cli\u003eDesigned for use in battery protection, inverter input and high-current DC distribution applications.\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 45g per pack, minimising additional load in compact installations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eMEGA fuses are a widely used format in DC electrical protection, particularly in battery-based systems where high fault currents can cause rapid cable damage or fire risk. The 400A rating makes this fuse appropriate for large inverter installations, battery banks and high-current DC busbars where standard ANL or blade fuses would be undersized.\u003c\/p\u003e\n\n\u003cp\u003eThe 80V DC voltage rating covers all common battery voltages used in off-grid and marine systems, including 12V, 24V and 48V configurations. It is important to select a fuse with a voltage rating at or above the system voltage to ensure the fuse can safely interrupt fault current without arcing. This fuse meets that requirement across the full range of typical Victron system voltages.\u003c\/p\u003e\n\n\u003cp\u003eVictron specifies MEGA fuses for use with their MEGA fuseholders, which are sold separately. The fuse is a consumable component and should be replaced after any overcurrent event. Keeping a pack of five on site means replacements are available during commissioning or in the event of a fault.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: CIP138400020\u003c\/li\u003e\n  \u003cli\u003eCurrent rating: 400A\u003c\/li\u003e\n  \u003cli\u003eVoltage rating: 80V DC\u003c\/li\u003e\n  \u003cli\u003eFuse type: MEGA blade fuse\u003c\/li\u003e\n  \u003cli\u003ePack quantity: 5 fuses\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.045 kg (per pack)\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076061748\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eBattery cable protection on 12V, 24V and 48V DC systems.\u003c\/li\u003e\n  \u003cli\u003eInverter input fusing on high-current installations.\u003c\/li\u003e\n  \u003cli\u003eDC distribution boards and busbars in off-grid solar systems.\u003c\/li\u003e\n  \u003cli\u003eMarine and vehicle electrical systems requiring high-current overcurrent protection.\u003c\/li\u003e\n  \u003cli\u003eReplacement fuses for existing MEGA fuseholder installations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e5 x Victron MEGA fuse 400A\/80V\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eMEGA fuses must be installed in a compatible MEGA fuseholder (sold separately). Always isolate the battery bank before replacing or installing fuses. Fuse selection should be based on cable rating and system design, not solely on inverter or load current draw. For battery systems above 48V or in grid-connected installations, a qualified electrician or MCS-accredited installer should carry out all wiring and protection work. Never bypass or replace a blown fuse with a higher-rated fuse without first identifying and resolving the cause of the overcurrent event.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":55582482465059,"sku":"CIP138400020","price":33.78,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0863\/9001\/4243\/files\/mega_fuse_victron_400Amps_bcf7930b-e08a-4862-9b1b-2ceb9ed7eb1f.webp?v=1789118555","url":"https:\/\/voltaconsolar.eu\/products\/mega-fuse-400a-80v-victron-pack-of-5","provider":"VoltaconSolar EU","version":"1.0","type":"link"}
