Blue Sea Systems ANL Fuse, 80V DC, 6000A AIC, Silver-Plated Blades, Blown Fuse Indicator

Overview

The Blue Sea Systems ANL Fuse is a bolt-down fuse range for high-current DC circuit protection on boats, with amperage options from 35A to 750A. It is used with ANL fuse blocks in main battery feeds, inverter circuits, windlass feeds, bow thruster circuits, and other large DC loads where the fuse must be matched to the cable size and equipment draw.

Each fuse has silver-plated connector blades to help maintain a clean electrical contact in marine environments, along with a visible blown-fuse indication that makes troubleshooting faster at the battery bank or DC distribution panel. The range carries a 6,000 Ampere Interrupt Capacity and a maximum voltage rating of 80V DC, giving it the headroom needed for common 12V, 24V, and higher-voltage DC marine systems within the rated limits.

Ratings from 35A through 500A are ignition protected to SAE J1171 for installation aboard gasoline-powered boats when installed as part of a suitable system. The 600A and 750A options are intended for high-current DC applications but are not ignition protected.

Key features

• ANL fuse format for use with Blue Sea Systems ANL fuse blocks in high-current DC circuits.
• Available amperage range covers 35A to 750A, allowing the fuse rating to be matched to the protected circuit.
• 6,000 Ampere Interrupt Capacity supports main DC circuit protection on large battery banks.
• Maximum voltage rating of 80V DC for use within properly specified marine DC systems.
• Silver-plated connector blades help resist corrosion at the contact points.
• Visible blown-fuse indication helps identify an open fuse without unnecessary disassembly.
• 35A to 500A ratings are ignition protected to SAE J1171 for use aboard gasoline-powered boats.

Variants

This ANL fuse range varies by amperage rating. The available options cover 35A, 40A, 50A, 60A, 80A, 100A, 130A, 150A, 175A, 200A, 250A, 300A, 350A, 400A, 500A, 600A, and 750A.

The fuse format, silver-plated connector blades, visible blown-fuse indication, 6,000 Ampere Interrupt Capacity, and 80V DC maximum voltage rating remain consistent across the range. Ignition protection applies to the 35A through 500A ratings only, so the 600A and 750A options should be used only where ignition protection is not required.

Installation and fit

This fuse installs in a compatible ANL fuse block and should be mounted where the protected conductor is as short as practical from the power source, following the vessel’s wiring plan and applicable marine electrical standards. Clean, flat contact surfaces and properly torqued fasteners are important because ANL fuses are used in circuits where poor connections can create heat.

The fuse rating should be selected for the wire size and the equipment being protected, not only for the load nameplate. For motor loads such as windlasses, thrusters, and pumps, starting current and manufacturer recommendations should be checked before selecting the amperage.

Use cases on board

This range is a good match for boat owners, installers, and service yards building or maintaining high-current DC systems. Common placements include battery bank outputs, inverter and charger feeds, DC panel supply circuits, windlass circuits, and other equipment feeds that need a serviceable fuse with clear visual fault indication.

Maintenance and care

During routine electrical checks, inspect the fuse and holder for heat marks, loose fasteners, corrosion, or damage around the contact blades. Replace a blown fuse only after the cause of the fault has been found, and always use the same fuse type and the correct amperage for the protected circuit.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
