Blue Sea Systems 5175 30A Battery Terminal Fuse — 10,000 AIC, visible blown indicator (blue/sea)

The Blue Sea Systems 5175 is a 30-amp battery terminal fuse engineered to meet ABYC DC main protection standards for large battery banks while providing a clear visual blown indication.

This compact electronic switch-style fuse is built for marine and mobile power systems where high interrupt capacity and safe, visible protection are essential. Designed to work with Blue Sea Systems terminal fuse blocks, it delivers 10,000 AIC at 14 V DC to satisfy ABYC requirements for main circuit protection on larger battery banks. The 5175 must be installed in an approved terminal fuse block (PN 5191 or PN 2151) rather than mounted directly to a battery terminal, and its clear blown indication speeds troubleshooting aboard boats, RVs, and other vehicles.

How does the 5175 fuse protect a large battery bank?

The 5175 provides high interrupt capacity and reliable overcurrent protection for DC main circuits. Its 10,000 AIC rating at 14 V DC means it can safely interrupt large fault currents without catastrophic failure, aligning with ABYC guidance for main protection.

• 10,000 AIC (arc-interrupting capacity) at 14 V DC for robust fault handling
• Rated continuous current: 30 amps for main-feed circuits
• Electronic-switch form factor for consistent operation
• Visible blown indicator to identify failures quickly

What installation requirements should I know before fitting the fuse?

Installation must use a compatible terminal fuse block; the fuse is not intended to be mounted directly to a battery post. Using PN 5191 or PN 2151 ensures correct mechanical and electrical fit, and helps maintain safe spacing and secure connections in the battery compartment.

• Mount only in Terminal Fuse Block PN 5191 or PN 2151
• Do not install directly on battery terminals or posts
• Follow ABYC and manufacturer torque and wiring practices
• Place within accessible reach for inspection and replacement

How will I know if the fuse has blown?

The 5175 includes a visible blown-condition indicator so you can confirm a fault without removing the fuse or testing with instruments. This visual cue speeds diagnosis and minimizes downtime onboard.

• Clear, built-in blown indicator visible when fuse opens
• Enables quick on-boat visual checks before deeper troubleshooting
• Reduces time spent tracing faults in complex DC systems

What are the product dimensions and type for planning layout?

The 5175 is an electronic-switch type protective device in a compact package that fits standard Blue Sea terminal fuse blocks. Use the physical dimensions to plan panel and block spacing in tight battery compartments.

• Product type: Electronic switch
• Package dimensions: 2.032 cm L × 3.556 cm W × 7.112 cm H
• Designed to mate with Blue Sea PN 5191 and PN 2151 blocks

Who is this for? The Blue Sea Systems 5175 30A fuse is intended for boat owners, marine electricians, RV technicians, and anyone managing larger DC battery banks who requires ABYC-compliant main circuit protection with a high interrupt rating and simple, visible fault indication. Choose the 5175 when you need a compact, reliable protective device that integrates with Blue Sea terminal fuse blocks and makes fault identification faster and safer.
