MAXI fuse for 80-amp circuit protection in marine, automotive, and RV electrical systems, with visible status indication for faster troubleshooting.

The Blue Sea Systems 5143 is an 80A MAXI fuse for protecting compatible DC branch circuits from excessive current. Tin-plated connector blades help resist corrosion in damp operating environments. Its visible blown-fuse indication makes inspection easier without relying solely on electrical testing.

  • 80A MAXI fuse: Provides the specified fuse rating for compatible circuit-protection applications.
  • Tin-plated connector blades: Help resist corrosion in marine, automotive, and RV environments.
  • Visible blown-condition indication: Makes it easier to identify a failed fuse during maintenance.
  • Marine and vehicle electrical use: Fits common fuse-replacement needs in boating, automotive, and RV systems.

Use the Blue Sea Systems 5143 as a replacement MAXI fuse in a compatible 80-amp circuit-protection application. MAXI fuses are commonly used in higher-current DC branch circuits found in boats, recreational vehicles, and automotive electrical systems.

The tin-plated connector blades are suited to electrical installations where moisture and corrosion are concerns. When the fuse opens, its visible indication helps technicians locate the failed protection device before testing or replacing it. Confirm the equipment manufacturer’s required fuse type and rating before installation, and replace only with an equivalent 80A MAXI fuse.
