Fuses

Fuses protect cables from overheating and fire when a short circuit or overload occurs. This collection includes Class T fuses for battery banks, ANL fuses up to 500A, Victron MEGA fuses for Lynx distributors, Victron CNN fuses for the Lynx Shunt, Maxi and ATC blade fuses for branch circuits, and Victron modular fuse holders for MEGA fuses.

How to choose a marine fuse

• Rating: size the fuse to protect the cable ampacity, not just the load.
• Interrupt capacity: large lithium banks need high-interrupt fuses such as Class T.
• Voltage: confirm the fuse DC voltage rating, especially for 48V systems.
• Location: fit the main fuse as close to the battery as possible.

Class T or ANL?

Class T fuses have a much higher interrupt rating and are recommended for large lithium banks; ANL fuses suit many other high-current circuits.

Where are fuse holders?

See fuse holders and fuse blocks, or circuit breakers.

Do I need a fuse for every circuit?

Yes. Every positive conductor should be protected near its source by a fuse or breaker sized to the wire.
