MEGA/AMG fuses provide 150-amp circuit protection for marine, RV, automotive, and other high-current DC electrical systems using a compatible fuse block.

This Blue Sea Systems 5103 fuse is rated at 150 amps and fits Blue Sea Systems MEGA/AMG fuse blocks. It provides economical protection for circuits in the 100–300 amp range, helping limit damage from excessive current. The fuse is ignition-protected and rated for systems up to 70V DC.

  • 150A rating: Provides circuit protection for high-current DC applications.
  • MEGA/AMG configuration: Fits compatible Blue Sea Systems MEGA/AMG fuse blocks for straightforward replacement.
  • Ignition-protected design: Suitable for compatible installations where ignition protection is required.
  • 2,000A interrupt capacity at 32V DC: Helps interrupt high fault currents in supported 32V DC systems.
  • Broad application range: Supports marine, RV, automotive, and other 100–300 amp circuit-protection setups.

Use the Blue Sea Systems 5103 as a replacement or service fuse in a compatible MEGA/AMG fuse-block installation. Its 150-amp rating suits high-current circuits commonly found in boats, recreational vehicles, and automotive electrical systems.

The fuse installs into a MEGA/AMG fuse block rather than serving as a standalone connection point. Confirm the fuse-block configuration, circuit requirements, conductor rating, and manufacturer guidance before installation or replacement.

With ignition protection and a maximum voltage rating of 70V DC, the 5103 supports appropriately specified low-voltage DC systems. Always match the replacement fuse to the required circuit rating and use a qualified installer when working on energized or complex electrical systems.
