ST-Blade Fuse Blocks

Consolidates branch circuits and in-line fuses

The ST Blade Fuse Block was designed with fastener terminals to comply with ABYC Recommended Practices, and are built with tin-plated copper components for improved conductivity and lower operating temperatures. An optional cover protects the conductive surfaces from accidental shorting, labels each circuit, and stores spare fuses.

The ST Blade Fuse Block is ideal for use as a sub-panel in the DC distribution system. This solves the problem of using large and expensive circuit breaker panels as circuit protection for electronics and other branch circuits. With most circuit breaker panels a circuit breaker and an inline fuse are used for to protect electronic devices. By instead utilizing Blue Sea Systems ST Blade Fuse Block as a sub-panel, fuses more appropriate for electronics can be used, removing the need for inline fuses while only utilizing one position on the panel. This reduces the size of the panel needed and lowers the overall system cost.

  • Independent and/or Common Source fuse block
  • Fastener terminals for securing wires accept terminal rings
  • One-piece stainless flange nuts ensure safe and secure connections
  • Clear insulating cover with label recess satisfies ABYC/USCG insulation requirements
  • Accepts ATO and ATC fast acting blade fuses (sold separately)
  • Some models ignition protected or ingress protected
