Blue Sea Systems 5029 ST Blade Fuse Block, 12 Circuit with Cover, 100 Amp

The Blue Sea Systems 5029 is a 12 circuit ST Blade fuse block built for organized, high capacity DC power distribution aboard boats, RVs, work trucks, and custom 12/24 volt electrical systems. Each of the twelve circuits accepts standard ATO or ATC fast acting blade fuses (fuses sold separately) and is rated for up to 30 amps per circuit, with the block rated for a total of 100 amps at up to 32 volts DC. A positive distribution bus with a #10-32 stud feeds all twelve circuits from a single source, while screw terminal connections at #8-32 with captive star lock washers give a secure, vibration resistant wire termination.

A clear, snap on insulating cover protects the terminals from accidental shorts and debris, and doubles as onboard storage with recesses for two spare fuses and space for write on circuit labels (20 included) so every circuit stays identified at a glance. The push button latch makes the cover easy to open for inspection or fuse changes without tools. Terminals accept ring or spade type connectors, and the fuse block mounts with #8 (M4) screws for a stable, panel mounted installation. Backed by a lifetime warranty, the Blue Sea Systems 5029 is a durable, professional grade choice for consolidating multiple 24-hour or switched circuits behind one protected, easy to service panel.
