Victron Energy ANL Fuse, 80V, Bolt-Down, Fast-Acting, 5pk

Overview

The Victron Energy ANL-Fuse 80V is a bolt-down ANL fuse range for high-current DC protection in 48V battery and inverter systems. Each pack contains five fuses in the selected current rating, with 400A and 500A versions available for installations that need protection at higher current levels.

These fuses suit marine electrical systems where large DC loads, battery banks, chargers, inverters, and energy storage equipment need properly sized circuit protection. The 80V rating gives the needed voltage headroom for 48V systems, including many modern onboard lithium and inverter-based power setups.

The ANL body format uses slotted terminals for secure mounting in a compatible ANL fuse holder. The shared body measures 82 mm overall length, with a 32 mm center body section and 0.8 mm fuse element thickness, which helps installers confirm physical fit before replacing an existing fuse.

Key features

• 80V ANL fuse format for high-current DC systems, including 48V marine power installations.
• Available in 400A and 500A current ratings for matching the fuse to the cable, battery, and equipment protection requirements.
• Bolt-down connection style keeps the fuse mechanically secured inside a compatible ANL holder.
• Fast-acting fuse construction helps interrupt overcurrent conditions in battery and inverter circuits.
• Package of five fuses supports service spares, refit work, or multi-circuit installations using the same rating.
• Shared 82 mm ANL body length helps with replacement planning where space inside the DC distribution area is limited.

Variants

This Victron Energy ANL-Fuse 80V range is offered in multiple current ratings for high-current DC protection.

The current rating changes between variants, while the ANL format, 80V voltage rating, 48V-product application, and five-piece package remain consistent across the range.

• CIP143400020, current rating 400A. This version has an approximate voltage drop of 125 mV and a cold resistance of 0.16 mO, making it the lower-current option in this range.
• CIP143500020, current rating 500A. This version has an approximate voltage drop of 100 mV and a cold resistance of 0.25 mO, giving higher current capacity for systems specified around a 500A ANL fuse.

What’s included

• Five ANL fuses in the selected current rating

Installation and fit

Install this fuse in a compatible ANL fuse holder and place it as close as practical to the protected battery or DC source, following the vessel’s electrical plan. The final fuse rating should match the protected cable size and connected equipment requirements, not only the expected load current.

Because this is a high-current DC component, clean contact surfaces and tight hardware matter. Loose connections can create heat, voltage drop, and nuisance faults, especially on boats where vibration, charging cycles, and heavy inverter loads are part of normal use.

Compatibility and use on board

This fuse range is a practical match for marine DC systems built around 48V equipment, including inverter banks, charger circuits, and battery distribution where ANL fuse holders are already specified. It is also useful during refits where the existing protection scheme calls for an 80V ANL fuse with the same physical format.

It should be installed in a dry, protected electrical area rather than exposed directly to spray or bilge moisture. For saltwater boats, keeping the fuse holder clean and protected from corrosion helps maintain low-resistance connections over time.

Maintenance and care

Inspect the fuse and holder during routine electrical checks, especially after a fault event, heavy inverter use, or battery system work. Replace a blown fuse only after the cause has been found and corrected, and use the same current rating unless the electrical system has been reviewed and updated.

Shipping
We ship worldwide from the United States. Rates are calculated at checkout based on destination and package weight. Some items include free shipping, which will show automatically. Not every product is eligible for international shipping; checkout will confirm eligibility. We do not ship to PO Boxes except through USPS, and not all packages qualify.

Processing and dispatch
Most orders are verified, packed, and handed to the carrier within 1 to 2 business days. Some products may need extra handling time or ship directly from the manufacturer. For certain international orders, inventory transfers between warehouses may add time. If any delay is expected, we will let you know the dispatch date.

Delivery and tracking
Deliveries are handled by trusted carriers such as USPS, UPS, FedEx, and DHL. Estimated arrival times appear at checkout and depend on your location and the service you choose. These are estimates and can be affected by customs or carrier disruptions. A shipping confirmation with a tracking link is emailed when your order ships, and tracking may take up to 24 hours to update. You can also view tracking in your account.

Duties, taxes, and support
International customers are responsible for any customs duties, taxes, and fees charged by the destination country. If these charges are refused and a shipment returns to us, the carrier’s return cost and any re-entry customs fees will be deducted from the refund. If your order is late or you need help, contact cs@qualityboatparts.com and we will assist you.

Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.

Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.

To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.
