Product Details

The Blue Sea Systems 2151 Double Battery Terminal Fuse Block provides circuit protection directly at the battery terminal without requiring wire cutting. This innovative design allows you to attach the fuse block directly to your battery post, select the appropriate fuse (30A-300A), and connect your conductors—ideal for space-constrained installations.

Key Features:

  • Isolated stud design uses standard 5/16" hardware and permits stacking of terminals
  • Dual fuse positions for protecting two separate high-amperage circuits
  • Perfect for DC main, inverter, windlass, and bow thruster circuit protection
  • Weatherproof construction suitable for harsh marine environments and open-cockpit boats
  • Ignition protected for safe installation in gasoline-powered boat engine rooms
  • Insulating cap prevents accidental short circuits and terminal contact
  • Compact design delivers high current protection in tight spaces

Specifications:

  • Maximum amperage: 300A
  • Voltage rating: 58V DC
  • Terminal stud size: 5/16"
  • Number of fuse positions: 2
  • Compatible with 5/16" or 3/8" ring terminals

This double fuse block is engineered for marine and RV applications where reliable circuit protection and space efficiency are critical. Fuses sold separately.

We ordered a cover for a pickup truck bed and were so pleased that it was shipped so quickly. The price was the lowest that we found on the internet or in any of the stores where we looked. We were notified by e-mail as soon as it shipped. We will definitely shop this site again.
