It accepts 18 to 4 AWG wire, with terminals that connect from either the sides or the bottom of the block, giving installers flexibility when running wire in tight panel spaces. The block is rated for a maximum voltage of 32 VDC and is built from reinforced polycarbonate, a material chosen for its resistance to corrosion and impact in a marine environment. A snap-on cover insulates the conductive terminals from accidental contact, helping the installation meet ABYC and USCG requirements. The FS81080 meets SAE J1171, the SAE standard for marine electrical devices. It is commonly used as a central distribution point for high-current circuits such as bilge pumps, windlasses, and battery feeds where a Maxi fuse is the appropriate overcurrent protection. Because it is a single-position block, one FS81080 protects one circuit; multiple blocks or a fuse block bank are used for boats with several high-current circuits. The compact housing measures 0.39 x 0.39 x 0.39 inches and weighs 0.26 pounds, making it easy to mount within existing electrical panels or battery compartments.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e FS81080\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Maxi Fuse Block\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Marine Fuse Blocks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Type Accepted:\u003c\/strong\u003e Maxi fuses, 30-80 Amp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Voltage:\u003c\/strong\u003e 32 VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Acceptance:\u003c\/strong\u003e 18-4 AWG, from sides or bottom\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard Met:\u003c\/strong\u003e SAE J1171\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Reinforced polycarbonate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.26 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size fuses does the Sierra FS81080 fuse block accept?\u003c\/strong\u003e It is built for Maxi-style fuses rated from 30 to 80 amps, the larger blade-style fuses used for high-current marine circuits.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the maximum voltage rating of this fuse block?\u003c\/strong\u003e The FS81080 is rated for a maximum of 32 VDC, suitable for standard 12-volt and 24-volt marine electrical systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat wire sizes can be connected to the FS81080?\u003c\/strong\u003e It accepts wire from 18 AWG up to 4 AWG, and terminals can be wired from either the sides or the bottom of the block.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the fuse block made of?\u003c\/strong\u003e The Sierra FS81080 is made of reinforced polycarbonate, a durable plastic chosen for its impact resistance in marine electrical panels.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the FS81080 meet marine safety standards?\u003c\/strong\u003e Yes, it meets SAE J1171, the SAE standard governing marine electrical and electronic devices, and its snap-on cover supports ABYC and USCG compliance for insulated conductive parts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs there a cover over the terminals?\u003c\/strong\u003e Yes, the FS81080 has a snap-on cover that insulates the conductive terminals from accidental contact.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many circuits does one FS81080 fuse block protect?\u003c\/strong\u003e The FS81080 is a single-position Maxi fuse block, so it protects one circuit; boats needing multiple high-current circuits protected would use additional blocks.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions and weight of this fuse block?\u003c\/strong\u003e The Sierra FS81080 measures 0.39 x 0.39 x 0.39 inches and weighs 0.26 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the FS81080 fuse block?\u003c\/strong\u003e It is black.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat typical marine circuits use a Maxi fuse block like the FS81080?\u003c\/strong\u003e High-current circuits such as bilge pumps, windlasses, and main battery feed lines typically use Maxi fuses in the 30 to 80 amp range that the FS81080 is designed to hold.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988454158555,"sku":"SIE-FS81080","price":29.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/FS81080__13868.1722497397.500.750.jpg?v=1785188201"},{"product_id":"sierra-fs79370-marine-boat-fuse","title":"Sierra Fuse FS79370 for Boat Electrical Systems","description":"\u003cp\u003eThe Sierra FS79370 is a replacement fuse designed for marine electrical systems, providing circuit protection for boat wiring and onboard electronics.

Keeping a set of spares on board is a simple way to restore power to a dead circuit without diagnosing a wiring fault first.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sea-Dog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 445103-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Type:\u003c\/strong\u003e ATO\/ATC Blade Fuse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e 3 Amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Quantity:\u003c\/strong\u003e 5 fuses\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Through-Hole Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Ceramic, Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 3.75 x 1.88 x 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.026 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 035514446365\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eHow many fuses come in this pack?\u003c\/strong\u003e Sea-Dog part number 445103-1 is sold as a 5-pack, giving you five 3-amp ATO\/ATC blade fuses per package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat amperage is this fuse rated for?\u003c\/strong\u003e Each fuse in this Sea-Dog 445103-1 pack is rated at 3 amps, intended for light-duty circuits such as gauges, indicators, and small electronics.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat style of fuse holder does this fit?\u003c\/strong\u003e This is a standard ATO\/ATC blade-style fuse, so it fits any ATO\/ATC fuse holder or fuse block, marine or automotive.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the fuse body made of?\u003c\/strong\u003e The Sea-Dog 445103-1 fuse uses a ceramic body with copper terminals, a common and durable construction for blade-style fuses.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this fuse suitable for marine use?\u003c\/strong\u003e Yes, Sea-Dog markets the 445103-1 fuse for boat electrical systems, and its ATO\/ATC blade format is widely used in marine fuse panels.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is this fuse mounted?\u003c\/strong\u003e The 445103-1 fuse uses a through-hole mount, meaning its two blade terminals push directly into the receptacle contacts of a compatible fuse holder.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the fuse package?\u003c\/strong\u003e The 445103-1 5-pack measures 3.75 x 1.88 x 0.75 inches as packaged.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this fuse pack weigh?\u003c\/strong\u003e The Sea-Dog 445103-1 fuse pack weighs 0.026 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use this fuse to replace a blown 3-amp fuse in my boat's panel?\u003c\/strong\u003e Yes, because it is a standard 3-amp ATO\/ATC blade fuse, the 445103-1 can replace any blown fuse of the same ATO\/ATC style and amperage rating.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for this product?\u003c\/strong\u003e The UPC for the Sea-Dog 445103-1 fuse 5-pack is 035514446365.\u003c\/p\u003e","brand":"Sea-Dog","offers":[{"title":"Default Title","offer_id":48988814246107,"sku":"S-D-445103-1","price":2.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/5174.jpg?v=1784429595"},{"product_id":"sea-dog-445105-1-atc-ato-blade-fuse-5-amp-pack-of-5-tin-plated-copper-marine-fuse","title":"Sea-Dog ATC\/ATO Automotive Fuse, 5 Amp, Pack of 5 (445105-1)","description":"\u003cp\u003eThe Sea-Dog 445105-1 is a standard ATC\/ATO blade-style automotive fuse rated at 5 amps, sold in a pack of 5.

Because it ships without a negative (ground) bus, it is intended for installations where each circuit's return path is wired independently rather than tied to a shared common bus bar, giving the installer full control over how negative connections are routed. Each of the six positions accepts standard ST (mini) blade fuses and is rated to carry up to 30 amps per circuit, making the block suitable for a wide range of accessory, lighting, pump, and electronics circuits. Screw-type connectors secure the incoming and outgoing wiring at each position for a solid, vibration-resistant termination. The block is molded from plastic with an upper temperature rating of 125 degrees Celsius, and the included cover helps shield the live terminals and fuses from accidental contact and stray splash. Compact at 2 inches wide by 1.5 inches high, the 5028 mounts to a bulkhead or panel surface, keeping fuse blocks and circuit wiring tidy in tight helm, console, or engine compartment spaces.

Sea Systems 5063 Heavy Duty In-Line AGC\/MDL Fuse Holder, IP66 Water-Resistant Panel Mount","description":"\u003cp\u003eThe Blue Sea Systems 5063 is a heavy duty in-line fuse holder built for AGC\/MDL style fuses in demanding marine electrical installations. It mounts directly to a panel and is rated IP66, meaning the front of the holder is protected against powerful water jets, making it suitable for exposed or wet locations onboard. The holder accepts 12-18 AWG wire and supports fuse amperages up to 20 Amps, giving installers flexibility when protecting a range of circuits from lighting and pumps to accessory wiring. Installation is straightforward: the holder mounts through a 0.50 inch (12.70 mm) panel hole, allowing a clean, secure fit without extra brackets or hardware. The housing is molded from durable plastic in a beige finish, sized at 5 x 2 x 1 inches, and is built to withstand the vibration and moisture typical of marine environments. The fuse itself is sold separately, so buyers should have their appropriate AGC\/MDL fuse on hand before installation. This fuse holder is a straightforward, reliable way to add in-line overcurrent protection to a DC circuit without the bulk of a full fuse block, and its water-resistant rating makes it a practical choice anywhere the circuit run is exposed to spray or splash.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Blue Sea Systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 5063\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Type:\u003c\/strong\u003e AGC\/MDL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Fuse Amperage:\u003c\/strong\u003e 20 Amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Style:\u003c\/strong\u003e Panel Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Resistance Rating:\u003c\/strong\u003e IP66 (front-protected against powerful water jets)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hole Diameter:\u003c\/strong\u003e 0.50 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Gauge:\u003c\/strong\u003e 12-18 AWG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 5 x 2 x 1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Beige\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.03 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat fuse type does the Blue Sea Systems 5063 fuse holder use?\u003c\/strong\u003e The Blue Sea Systems 5063 accepts AGC\/MDL style fuses, which are sold separately from the holder.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 5063 fuse holder waterproof?\u003c\/strong\u003e It carries an IP66 rating on the front, meaning the Blue Sea Systems 5063 is protected against powerful water jets, making it suitable for exposed marine locations.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size mounting hole does the 5063 fuse holder require?\u003c\/strong\u003e A 0.50 inch (12.70 mm) panel hole is needed to mount the Blue Sea Systems 5063 in-line fuse holder.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat wire gauge works with this fuse holder?\u003c\/strong\u003e The 5063 fuse holder accepts 12-18 AWG wire.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the maximum fuse amperage for the Blue Sea Systems 5063?\u003c\/strong\u003e 20 Amps is the maximum fuse amperage rating for the 5063 fuse holder.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 5063 come with a fuse included?\u003c\/strong\u003e No, the fuse is sold separately from the Blue Sea Systems 5063 fuse holder; only the holder itself is included.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 5063 fuse holder made from?\u003c\/strong\u003e The housing is molded from plastic in a beige finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Blue Sea Systems 5063?\u003c\/strong\u003e The 5063 fuse holder measures 5 x 2 x 1 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 5063 fuse holder weigh?\u003c\/strong\u003e The Blue Sea Systems 5063 weighs 0.03 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the 5063 fuse holder mounted?\u003c\/strong\u003e It is a panel mount design, installed through a 0.50 inch hole in the panel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 5063 fuse holder be used in exposed or wet locations on a boat?\u003c\/strong\u003e Yes, its IP66 rating protects the front of the Blue Sea Systems 5063 against powerful water jets, so it is designed for exposed marine installations.\u003c\/p\u003e","brand":"Blue Sea Systems","offers":[{"title":"Default Title","offer_id":48989500637403,"sku":"BSS-5063","price":6.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/5063.jpg?v=1784507488"},{"product_id":"blue-sea-systems-5056-st-blade-water-resistant-4-circuit-fuse-block-32v-dc-80a-ato-atc-fuses-circuit-breakers","title":"Blue Sea Systems 5056 ST-Blade Water-Resistant 4 Circuit Fuse Block, 32V DC","description":"\u003cp\u003eThe Blue Sea Systems 5056 is a water-resistant ST-Blade fuse block that provides circuit protection for up to four separate circuits in a compact footprint.

It accepts wire from 12 to 18 AWG and comes supplied with 12 AWG pigtail leads on each end, ready to be spliced or crimped into an existing circuit. Maximum fuse amperage is 30 Amps, so it is sized for lighting circuits, pumps, electronics, and other moderate-draw accessory loads rather than high-current feeds. The fuse itself is sold separately, so pick the ATO or ATC amperage rating that matches the circuit you are protecting.
