Show original supplier description
The Blue Sea Systems 5026 ST Blade Fuse Block is engineered to manage and protect 12 individual circuits using standard ATO/ATC automotive blade fuses, rated from 1 to 30 Amps. This fuse block features tin-plated copper buses and fuse clips, ensuring a robust connection with a 30 Amp rating per circuit and a total capacity of 100 Amps for the block. It includes a ground bus for each circuit and accepts ATO and ATC fast-acting blade fuses. The unit comes with a clear, insulating polycarbonate cover that satisfies ABYC/USCG requirements and offers storage for two spare fuses. The cover also features label recesses for organization, and write-on labels are included. Installation is facilitated by screw terminals with captive lock washers to enhance vibration resistance. The #8 screw terminals are suitable for ring terminals. The product dimensions are 6.472" in height, 3.315" in width, and 1.518" in depth. It operates at a maximum of 32 VDC. Note that fuses are sold separately, and while one sample fuse is included, additional fuses should be purchased to complete the installation.
