Review: Perfect fit. - I had a fuse panel on an older boat that I needed to have new fuse holders for. These were a perfect replacement and worked great for me. I couldn't keep the fuses in the old ones anymore as the springs must have worn out so I was very pleased that these fit the panel perfectly and locked into place like they're supposed to. Review: Works with Both 1/4"x1-1/4" and 6x30mm Fuses - I bought this to replace a 5x20mm fuse holder rated at 15A, but got hot and lost 0.5+V at 10A. I tested this one and it held AGC/MDL, and 6x30mm fuses just fine. As others have written and Chinese influenced moron desertcart the fuse sizes are not the same. Some fuse holders can take both some cannot. It worked fine at 12V 10A with a 6x30mm SloBlo fuse (Chinese MDL semi-clone). 1/4" spade connectors held terminal fine as well. The plastic nut tightened down enough to smash the rubber gasket out. Had to readjust the nut to release the gasket. Overall, I am pleased with its performance. ## Features - Replaces fuse holder found in Contra Waterproof Fuse Panels - Easy to open - Withstands water exposures normally encountered in above deck applications: salt spray, rain, wash-downs ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000XBB8YI | | Best Sellers Rank | #15,571 in Automotive ( See Top 100 in Automotive ) #41 in Automotive Replacement Fuse Holders | | Brand Name | Blue Sea Systems | | Color | Black | | Customer Reviews | 4.6 4.6 out of 5 stars (1,743) | | EU Spare Part Availability Duration | 5 Years | | Global Trade Identification Number | 00632085050214 | | Included Components | Blue Sea 5021 Water Resistant Fuse Holder | | Item Dimensions | 5 x 3 x 1 inches | | Item Type Name | Blue Sea 5021 Water Resistant Fuse Holder | | Item Weight | 0.02 Pounds | | Manufacturer | Blue Sea Systems | | Material Type | Stainless Steel or Anodized Aluminum | | Maximum Current | 20 Amps | | Model | 5021 | | Mounting Type | Through-Hole Mount | | Part Number | 5021-BSS | | UPC | 632085050214 | | Unit Count | 1.0 Count | | Voltage | 32 Volts | | Warranty Description | Warranty | ## Product Details - **AC Adapter Current:** 20 Amps - **Brand:** Blue Sea Systems - **Item dimensions L x W x H:** 5 x 3 x 1 inches - **Material:** Stainless Steel or Anodized Aluminum - **Voltage:** 32 Volts ## Images ![5021 Panel Mount AGC/MDL Fuse Holder, Black - Image 1](https://m.media-amazon.com/images/I/51BPwld3SsL.jpg) ## Questions & Answers **Q: What size fuses does the blue sea systems panel mount agc/mdl fuse holder take ?** A: Fuse size 3AG, 6 X 30mm (1/4 inch by 1-1/4 inch) **Q: What is the amp rating?** A: It depends on the fuse you use.

Although the retaining nut was missing, it may have fallen off at the Amazon warehouse, but I had the original nut from the old fuse holder and it was a perfect fit. Mounted within a few minutes, soldered the wires into position and I was back milling parts without an issue. Yes, I would recommend this fuse holder. ## Frequently Bought Together - Blue Sea Systems 5021 Panel Mount AGC/MDL Fuse Holder, Black - BOJACK 6x30mm 15 A 15 amp 250 V 0.24x1.18 Inch Volt F15AL250V Fast-Blow Glass Fuses (Pack of 18) - BOJACK 5x20 mm 4 A 4 amp 125 V 125 Volt 0.2x0.78 Inch F4AL125V Fast-Blow Glass Fuses (Pack of 10) --- ## 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.kg/products/4021880-5021-panel-mount-agc-mdl-fuse-holder-black](https://www.desertcart.kg/products/4021880-5021-panel-mount-agc-mdl-fuse-holder-black) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-08*
