Review: Highest Quality - I have done several DIY solar projects. For safety, I always put a proper sized fuse at the battery. With this MRBF Terminal Fuse Block, I can simply mount the fuse right to the battery post. It is simple to mount, small and very high quality. I only needed a single fuse block, but they had a super special where the dual fuse block was way less expensive then a single fuse block. So I bought the double. This is a very well designed piece if equipment. The build quality is superb and it is made for harsh salt water environments. Review: Great Quality, high price. - This worked great on my 48v battery bank of 8 12v 280 AH ecoworthy batteries. Save so much wire and headaches with the bussbars. Note: do not get the cheaper bojack fuses as they have not been reliable in my experience. I did not like spending $18 for the better fuse but had to anyway… ## Features - Voltage Max Operating: 58V DC, Amps Max Operating: 300A per block, Terminal Fuses Avail.: 30A-300A, Terminal Stud Size: 5/16"-18 (8mm), Mounting Hole Size: #10 (5mm)3/8" - Compact, high-amp fuse—appropriate for DC Main, inverter, windlass, and bow thruster circuit protection - Weatherproof – suitable for small open-cockpit boats and other harsh environments - Insulating cap prevents accidental shorts - Ignition protected when used with MRBF fuses - Fuses sold separately ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002INJXO6 | | Best Sellers Rank | #7,896 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #2 in Fuse Blocks (Tools & Home Improvement) #6 in Fuse Blocks (Industrial & Scientific) | | Brand Name | Blue Sea Systems | | Color | Double Fuse | | Connector Type | Screw | | Current Rating | 300 Amps | | Customer Reviews | 4.7 out of 5 stars 249 Reviews | | Global Trade Identification Number | 00632085021511 | | Included Components | Item | | Item Dimensions W x H | 2.5"W x 3.5"H | | Item Type Name | fuse boxes | | Item Weight | 4.8 Ounces | | Manufacturer | Blue Sea Systems | | Material | Plastic | | Material Type | Plastic | | Model | 2151 | | Mounting Type | 3/8 inch threaded mount | | Number Of Contacts | 2 | | Number Of Poles | 2 | | Number of Positions | 2 | | Part Number | 2151 | | UPC | 632085021511 | | Voltage | 58 Volts (DC) | | Warranty Description | As labeled | ## Product Details - **Brand:** Blue Sea Systems - **Color:** Double Fuse - **Connector Type:** Screw - **Current Rating:** 300 Amps - **Manufacturer:** Blue Sea Systems - **Material:** Plastic - **Mounting Type:** 3/8 inch threaded mount - **Number Of Contacts:** 2 - **Product Dimensions:** 2.5"W x 3.5"H - **Voltage:** 58 Volts (DC) ## Images ![2151 - Image 1](https://m.media-amazon.com/images/I/61iQg3HoniL.jpg) ![2151 - Image 2](https://m.media-amazon.com/images/I/41aMH9iK-ZL.jpg) ## Available Options This product comes in different **Color, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Highest Quality *by S***E on March 11, 2026* I have done several DIY solar projects.

I made the switch from lead acid to LiFePO4 battery power with solar charging. I needed a compact device to provide a primary fused circuit breaker right at my 300 Sh battery. This does the job of providing protection at a reasonable cost. ## Frequently Bought Together - Blue Sea Systems 2151 Dual MRBF Terminal Fuse Block - 30 to 300A - Blue Sea Systems Terminal Fuses --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/10705401-2151](https://www.desertcart.ae/products/10705401-2151) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-07-09*
