ANL fuse block from Blue Sea Systems including ANL fuses

ANL fuses are used for protecting high current off-grid systems operating at up to 32V DC for Motorhomes, caravans, campervans and boats. They have a high interrupt capacity of 6000A @ 32V DC which satisfies ABYC requirements for main DC circuit protection of large battery banks.

This fuse block has stainless studs that provide corrosion resistance and allow for high torque, enabling excellent electrical contact, and the reinforced polycarbonate base has high heat resistance. The ‘swing-out’ design of the fuses enables replacement without removing the fasteners (eliminating the risk of losing them) and the supplied insulating cover has break-outs to allow wire access in any direction.

We supply the kit for as a fuse and holder either in 100A or 300A make sure you select the correct fuse size for your system. Most motorhomes and caravans will only require a 100A fuse where as large off-grid systems in campervans or upgraded motorhomes systems with large inverters require a larger 300A fuse.

The Blue Sea ANL is rated to interrupt up to 6,000 amps at 32 VDC, making it capable of safely isolating a fault even in powerful lithium systems. These fuses are essential to:
Prevent fires or catastrophic equipment damage in case of a short circuit.
Comply with safety standards like ABYC and ISO for marine and mobile power systems.
Protect wiring, inverters, DC-DC chargers, and other expensive system components from overcurrent damage.
In short, a genuine ANL fuse is not just a recommendation — it’s a safety-critical component in any lithium battery installation.
