Victron Energy ANL Fuse, For 48V Products, 80V, Bolt-Down, Fast-Acting

Overview

The Victron Energy ANL-Fuse is a bolt-down, fast-acting fuse for high-current DC protection in 48V Victron power systems and other installations that call for an ANL fuse within the same rating range. The range covers 300A, 400A, and 500A fuse ratings, each with an 80V maximum voltage rating, so it is suited to larger battery, inverter, charger, and DC distribution circuits where proper overcurrent protection is critical.

Its ANL format uses a bolted connection rather than a blade-style push fit, which helps keep the fuse secure in locations exposed to vibration, such as engine rooms, battery lockers, equipment compartments, and service panels on boats. These fuses have a higher short-circuit breaking capability than MEGA fuses, making them a practical choice where the installation calls for ANL protection on heavy DC cabling.

Key features

• ANL fuse format for high-current DC circuits on marine battery and power distribution systems.
• Available in 300A, 400A, and 500A ratings with an 80V maximum voltage rating.
• Fast-acting fuse construction helps interrupt overcurrent and short-circuit faults quickly.
• Bolt-down mounting keeps the electrical contact secure when installed in a compatible ANL fuse holder.
• Rated for 48V products, which makes the range useful for larger Victron inverter, charger, and battery system layouts.
• Higher short-circuit breaking capability than MEGA fuses for installations that require ANL-level protection.
• Compact fuse body measures about 82 mm long, with a 60 mm mounting-hole spacing for ANL holder fit checks.

Variants

This product is offered in several configurations so the fuse rating and pack quantity can be matched to the electrical design and service needs of the vessel.

The main differences between variants are the current rating and the number of fuses supplied. The 300A versions are available as a single fuse or a 5-unit pack, while the 400A and 500A versions are supplied as single fuses.

• CIP142300000: 300A/80V, 1 unit. This option suits a single protected circuit or a spare fuse position where the system design calls for a 300A ANL fuse.
• CIP143300020: 300A/80V, 5 units. This pack is useful when several matching 300A protected circuits are being installed or when spares are kept onboard for service.
• CIP142400000: 400A/80V, 1 unit. This option covers installations that require a higher current rating while staying within the same 80V ANL fuse format.
• CIP142500000: 500A/80V, 1 unit. This is the highest current rating in this listed range and should be used only where the cable, equipment, and protection plan call for a 500A ANL fuse.

Installation and fit

Install the fuse in a compatible ANL fuse holder with clean, tight bolted connections and cable lugs sized for the circuit. In a boat installation, the fuse should be placed where it can protect the conductor as intended while remaining accessible for inspection and replacement.

Fuse rating must match the protected cable, connected equipment, and the overall DC system design. For inverter, charger, or battery bank circuits, check the equipment requirements and the vessel wiring plan before selecting between 300A, 400A, and 500A.

Use cases on board

This fuse range is a good match for boats with larger DC loads, lithium or high-capacity battery banks, inverter/charger systems, and 48V Victron equipment where heavy conductors need properly rated overcurrent protection. It also works well as an onboard spare for cruising vessels where replacing a blown fuse quickly can keep essential power systems available.
