Blue Sea Systems 400A ANL Stud-Mount Fuse 5136 — 32V, 6,000 AIC, blown indicator

This compact, heavy-duty ANL fuse is built for marine and mobile power applications where dependable short-circuit and overload protection are essential. It combines high interrupt capacity, corrosion-resistant contacts, and a visual blown indicator in a form factor that installs into compatible ANL fuse blocks and holders. The 5136 is designed to meet demanding standards and to be a direct fit in many Blue Sea fuse blocks, offering a straightforward replacement option for main battery protection.

How does the 5136 fuse protect my boat or vehicle electrical system?

The 400A rating limits current to safe levels during faults, while the 6,000 A interrupt capacity ensures the fuse can clear high-energy short circuits without device failure. Silver-plated blades resist corrosion, keeping electrical contact reliable in moist or marine environments.

• Rated 400 amps continuous at up to 32 VDC
• 6,000 AIC (ampere interrupt capacity) for robust short-circuit clearing
• Silver-plated connector blades reduce corrosion and voltage drop
• Visible blown indicator for quick field inspection

Will the 5136 fit in my existing fuse block or panel?

The 5136 is a stud-mount ANL style fuse sized to fit many common ANL holders and specifically compatible with Blue Sea Systems 5004 and 5005 fuse blocks. Check stud spacing and physical dimensions to confirm fit before installation.

• Physical size: 3.185" long x 0.89" wide
• Stud-mount design for secure bolted connection
• Direct fit for Blue Sea 5004 and 5005 fuse blocks
• Compact profile suited for battery-main or inverter input circuits

Is the 5136 safe for gasoline-powered boats and compliant with standards?

This fuse conforms to ignition protection criteria for appropriate ranges and carries a visible blown indicator to aid maintenance checks. Its interrupt capacity and design meet common marine electrical standards for main DC circuit protection on larger battery banks.

• Ignition-protected construction for compatible amp ranges per SAE J1171
• 6,000 AIC helps satisfy ABYC-style requirements for main DC protection
• Visible blown condition for fast troubleshooting
• Silver-plated contacts for long-term reliability in corrosive environments

How should I choose and install this ANL fuse?

Select a fuse amp rating appropriate for the conductor and equipment you want to protect; the 400A rating is intended for high-current mains and inverter feeds. Install on a properly rated stud-type holder, torque the fasteners to manufacturer specs, and verify polarity and clearance to avoid heat buildup.

• Match fuse rating to wire and device protection requirements
• Use compatible stud-mount fuse blocks and correct torque values
• Leave adequate ventilation and clearance around the fuse
• Replace with identical ANL type to maintain protection characteristics

Who is this for? The Blue Sea Systems 5136 400A ANL fuse is aimed at boat owners, RV enthusiasts, and installers who need reliable main-battery or inverter protection for medium to large DC systems. If you manage high-current distribution, require an ignition-protected component for gasoline-powered craft, or want corrosion-resistant contacts and a visible blown indicator for easy maintenance, this fuse is a practical, serviceable choice. Always pair it with the correct fuse block and follow electrical safety and installation guidelines.
