Blue Sea Systems 60A Battery Terminal Fuse 60‑Amp — 10,000 AIC, Visible Blown Indicator

This compact fuse is designed for marine and mobile electrical systems where robust DC main protection is required. Built to meet ABYC expectations for short‑circuit performance, the 5178 provides a high interrupting capacity (10,000 AIC at 14V DC) while fitting into Blue Sea terminal fuse blocks. It is not intended to be mounted directly on a battery terminal — a compatible terminal fuse block is required for safe installation.

How does this fuse satisfy ABYC requirements for large battery banks?

The 5178 delivers a 10,000 amp interrupting rating at 14 volts DC, a level specified for reliable main‑circuit protection in larger installations. This rating reduces the risk of catastrophic failure if a high‑current short occurs.

• Interrupting capacity: 10,000 AIC at 14V DC
• Rated current: 60 amps for DC main circuits
• Engineered for larger battery banks and high‑fault current environments

What installation hardware do I need and where can I mount it?

The fuse must be installed in one of Blue Sea’s compatible terminal fuse blocks (PN 5191 or PN 2151). Do not attach the fuse directly to a battery post; using the proper block ensures secure electrical connections and mechanical support.

• Use terminal fuse block PN 5191 or PN 2151 only
• Avoid mounting directly on battery terminals to prevent poor connections and safety hazards
• Follow block manufacturer torque and wiring guidance for safe installation

How will I know if the fuse has blown?

The 5178 includes a visible indication feature so you can quickly determine a blown condition without disassembly. This makes troubleshooting faster and helps minimize downtime aboard a vessel or in a vehicle.

• Visible blown indicator for quick inspection
• Enables fast replacement and diagnostics
• Simplifies maintenance routines in cramped or hard‑to‑reach battery compartments

What physical and performance details should I expect?

The unit is compact and intended to work within Blue Sea’s terminal fuse ecosystem. Its small footprint allows space‑efficient installation while meeting demanding electrical performance specifications.

• Package dimensions: 8.89 cm L x 6.35 cm W x 1.27 cm H
• Current rating: 60 amps DC
• Designed to work with Blue Sea Systems fuse blocks for secure connections

Who is this for: The Blue Sea Systems 5178 60‑AMP Battery Terminal Fuse suits boat owners, RV and off‑grid system installers, electricians, and fleet technicians who need high‑capacity DC main protection that meets ABYC guidelines. It’s ideal when you require a compact, visible, and high‑interrupting fuse solution integrated into Blue Sea terminal fuse blocks for reliable, code‑aware installations.
