Blue Sea Systems ST Blade ATO/ATC Fuse Blocks
ST Blade ATO/ATC fuse blocks consolidate branch circuits and eliminate the tangle of in-line fuses for electronics and other appliances. Their robust design makes them ideal for marine and vehicle DC electrical systems.
All buses and fuse clips are tin plated copper for corrosion resistance and optimal electrical conductivity.
All ST Blade fuse blocks utilize a specialized fuse clip that is designed to hold fuses in place in the harshest conditions.
All fasteners are stainless steel. Screws contain a captive star lock washer for a faster more secure installation. Studs utilize flange nuts for a simpler and safer installation. Fuses sold separately.
