Product Details

The Blue Sea Systems 5026BSS is a professional-grade ST blade fuse block designed for marine and automotive DC electrical systems.

Key Features:

  • 12 independent fuse positions for ATO/ATC blade fuses
  • Common source design with single positive feed distribution
  • Integrated negative bus bar for consolidated ground connections
  • 32 Volt DC rated system with 100 amp block capacity
  • 30 amp maximum per individual circuit
  • Protective cover included to shield fuses from moisture and accidental contact
  • Tin-plated copper bus bars for corrosion resistance
  • Clear cover allows visual fuse inspection without removal

This fuse block is ideal for organizing and protecting electrical circuits in boats, RVs, and specialty vehicles.
