Fuse protection for medium- to high-amperage marine, automotive, and RV electrical systems, with a 175A rating for compatible Blue Sea Systems MEGA®/AMG® fuse blocks.

This MEGA®/AMG® fuse provides circuit protection for systems using 100–300 ampere fuse ratings. Its 175A capacity suits compatible battery and power-distribution circuits in boats, vehicles, and recreational vehicles. Install it with a Blue Sea Systems MEGA®/AMG® fuse block for a properly supported fuse connection. The fuse is ignition protected and rated for up to 70V DC.

  • 175A amperage rating: Helps protect compatible high-current electrical circuits from excessive current.
  • MEGA®/AMG® configuration: Fits Blue Sea Systems MEGA®/AMG® fuse blocks for compatible circuit-protection installations.
  • 100–300A fuse family: Supports selecting the appropriate fuse rating for medium- to high-amperage applications.
  • Ignition protected: Suitable for installations requiring an ignition-protected fuse.
  • Up to 70V DC: Provides a verified voltage rating for compatible direct-current systems.
  • 2,000A interrupt capacity at 32V DC: Helps interrupt high fault current within the stated operating condition.
The Blue Sea Systems 5104 is a 175A MEGA®/AMG® fuse for circuit-protection systems in marine, automotive, and RV applications. It installs into a compatible MEGA®/AMG® fuse block rather than serving as a standalone terminal connection. Use it in battery and power-distribution circuits where the electrical design calls for a 175A fuse rating. The MEGA®/AMG® format is part of a fuse family covering 100–300A circuit protection, allowing the rating to be matched to the protected circuit. Ignition protection supports use in applicable vehicle and marine electrical environments, while the stated 70V DC maximum and 2,000A interrupt capacity at 32V DC define its verified electrical limits.
