The Blue Sea 5026 fuse block is rated for a total capacity of 100 amps, with support for up to 30 amps per circuit when used with standard ATO or ATC blade fuses. Durable tin‑plated copper buses and fuse clips provide superior conductivity and corrosion resistance, ensuring reliable power distribution in harsh marine and mobile environments. A clear, snap‑on insulating cover protects terminals from accidental short circuits and includes built‑in storage for spare fuses along with recessed labeling areas for quick circuit identification. Designed for long‑term performance, the Blue Sea Systems 5026 is a trusted solution for professional‑grade DC fuse protection and power management." Review: A Go-To Fuse Block – I've Installed Several and Will Keep Coming Back to This One - A Go-To Fuse Block – I've Installed Several and Will Keep Coming Back to This One The Blue Sea Systems 5026 ST Blade Fuse Block is a flat-out outstanding product that earns every bit of 5 stars, and having installed several versions of it across different projects I can say with complete confidence that it is the fuse block to use. The 12-circuit layout with integrated ground and cover is thoughtfully engineered and makes for a clean, professional installation every time. The 100-amp capacity handles demanding electrical loads without any concerns, and the individual circuit fusing keeps everything properly protected and organized. The build quality is exactly what you expect from Blue Sea Systems—solid, marine-grade construction that holds up to vibration, heat, and the demands of vehicle, RV, boat, and off-grid solar applications equally well. The transparent cover protects the fuse connections from moisture and debris while still allowing a quick visual inspection of all circuits without removing anything. Labeling circuits is straightforward, wiring is clean and accessible, and the overall installation experience is as professional and reliable as the end result looks. For anyone building out a 12V electrical system on an RV, boat, truck, or solar setup, this is the fuse block I recommend without hesitation every single time. If you want to do your electrical system right, start here. Highest possible recommendation. Review: Great price and quality - Well built and designed fuse panel. I bought this to replace the power center in my A-Frame pop up trailer. I would prefer that the wire ends had a little more coverage as they leave the unit, but any wiring there should be properly terminated (crimped, soldered, and adhesive heat shrink applied) so that there are no chances for exposed conducting wires. Will have this installed in another week, looking forward to the final product that this is contributing to - well worth the price. ## Features - TWELVE CIRCUITS WITH GROUND: Supports twelve ATO or ATC fused branch circuits with integrated negative bus - 100 A MAXIMUM CAPACITY: Rated for up to 100 amps total capacity and supports up to 30 amps per circuit when used with standard ATO or ATC blade fuses, suitable for higher‑demand DC systems - INSULATING COVER: Clear protective cover features a secure push‑button latch, integrated spare fuse storage, and recessed label areas for simple circuit identification and maintenance - CORROSION RESISTANT: Tin‑plated copper buses and durable fuse clips resist corrosion and ensure long‑term conductivity in harsh automotive or marine environments - FLEXIBLE INSTALLATION: Accepts ring or snap fork terminals; suitable for twenty four hour circuits ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001P6FTHC | | Best Sellers Rank | #945 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1 in Fuse Blocks (Tools & Home Improvement) #1 in Fuse Blocks (Industrial & Scientific) | | Brand Name | Blue Sea Systems | | Color | With cover | | Connector Type | Screw | | Current Rating | 100 Amps | | Customer Reviews | 4.8 out of 5 stars 6,814 Reviews | | Global Trade Identification Number | 00632085050269 | | Included Components | Fuse Block, Cover, 20 write on circuit labels | | Item Dimensions W x H | 3.31"W x 1.5"H | | Item Type Name | boating-electrical-equipment | | Item Weight | 0.1 Kilograms | | Manufacturer | Blue Sea Systems | | Material | Polycarbonate (PC), Tinned plated copper | | Material Type | Polycarbonate (PC), Tinned plated copper | | Model | 5026 | | Mounting Type | screw mount | | Number Of Contacts | 12 | | Number Of Poles | 24 | | Number of Positions | 12 | | Part Number | 5026-BSS | | Specification Met | ISO 9000, SAE | | UPC | 632085050269 | | Unit Count | 1.0 Count | | Voltage | 32 Volts (DC) | ## Product Details - **Brand:** Blue Sea Systems - **Color:** With cover - **Connector Type:** Screw - **Current Rating:** 100 Amps - **Material:** Polycarbonate (PC), Tinned plated copper - **Mounting Type:** screw mount - **Number Of Contacts:** 12 - **Number Of Poles:** 24 - **Product Dimensions:** 3.31"W x 1.5"H - **Voltage:** 32 Volts (DC) ## Images ![Blue Sea Systems ST Blade Fuse Block 12 Circuit with Ground and Cover, 100 Amps, 5026 - Image 1](https://m.media-amazon.com/images/I/71vlKyD5mWL.jpg) ![Blue Sea Systems ST Blade Fuse Block 12 Circuit with Ground and Cover, 100 Amps, 5026 - Image 2](https://m.media-amazon.com/images/I/81u78rKcnnL.jpg) ![Blue Sea Systems ST Blade Fuse Block 12 Circuit with Ground and Cover, 100 Amps, 5026 - Image 3](https://m.media-amazon.com/images/I/71MOaA-Zq9L.jpg) ![Blue Sea Systems ST Blade Fuse Block 12 Circuit with Ground and Cover, 100 Amps, 5026 - Image 4](https://m.media-amazon.com/images/I/91Ef-cG4R5L.jpg) ![Blue Sea Systems ST Blade Fuse Block 12 Circuit with Ground and Cover, 100 Amps, 5026 - Image 5](https://m.media-amazon.com/images/I/61VnH+1ixAL.jpg) ## Available Options This product comes in different **Color, Style** options. ## Questions & Answers **Q: What size ring connector is needed to attach wire to terminals?** A: They are #8 as described in the description. Hard to find #8 rings in heat shrink connectors. #10 worked just fine for the terms and it seems all manufacturers sell this size. **Q: Can I run +/- from batt to 100 amp breaker then +/- to fuse box so I can kill power to fuse box?** A: Yes you can. The fuse box will be powered off breaker. I used a toggle switch panel instead of a main breaker. **Q: Product page says this can handle 100 amps per block, does that mean 100 amps on the left 6, and another 100 on the right?** A: No, it means 100a peak draw for the entire block...30a peak per circuit. The main positive in should be fused at 125 per the specs from BlueSea. **Q: Does this block come with a positive and a negative bus? I don't want to have to daisy chain the positive lead to each lead on the panel...** A: Yes, it does indeed come with both a positive (fused) bus and a negative bus. Very nice unit, as with all Blue Sea products. I would and have bought again after purchasing mine. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A Go-To Fuse Block – I've Installed Several and Will Keep Coming Back to This One *by J***N on April 13, 2026* A Go-To Fuse Block – I've Installed Several and Will Keep Coming Back to This One The Blue Sea Systems 5026 ST Blade Fuse Block is a flat-out outstanding product that earns every bit of 5 stars, and having installed several versions of it across different projects I can say with complete confidence that it is the fuse block to use.
