Sold individually, this larger amperage blade-style fuse uses tin-plated connector blades that resist corrosion in the marine environment, helping maintain a reliable electrical connection over time. The fuse body provides visible indication of a blown condition, so a quick visual check tells you whether the fuse has tripped without needing to remove it or use a meter. Its through-hole mount design fits standard MAXI fuse holders and blocks used throughout boat wiring systems. Constructed of plastic in a beige housing, the 5138 measures 5 x 3 x 1 inches and is built for straightforward swap-in replacement when a circuit needs a 30 amp rating. This is an economical option for boat owners maintaining battery, bilge pump, windlass, or other higher-draw circuits that call for MAXI-style fuse protection rather than smaller blade fuses.\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 5138\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e 30 Amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Style:\u003c\/strong\u003e MAXI blade-style fuse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Blades:\u003c\/strong\u003e Tin-plated for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlown Fuse Indication:\u003c\/strong\u003e Visible\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 Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Beige\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 5 x 3 x 1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRetail Pack Quantity:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat amperage is the Blue Sea Systems 5138 fuse rated for?\u003c\/strong\u003e The 5138 is rated for 30 amps, making it suitable for circuits that require a MAXI-style fuse at that amperage.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if the fuse has blown?\u003c\/strong\u003e The 5138 provides visible indication of a blown condition, so you can tell at a glance whether the fuse has tripped without removing it from the holder.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat style of fuse is this?\u003c\/strong\u003e It is a MAXI blade-style fuse, a larger-format blade fuse used for higher-amperage circuits than standard automotive blade fuses.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the 5138 mounted?\u003c\/strong\u003e This fuse uses a through-hole mount design, fitting standard MAXI fuse holders and fuse blocks built for that mounting style.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the fuse body made of?\u003c\/strong\u003e The Blue Sea Systems 5138 has a plastic housing in a beige color.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of this fuse?\u003c\/strong\u003e The 5138 measures 5 x 3 x 1 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 5138 fuse weigh?\u003c\/strong\u003e It weighs 0.04 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy are the connector blades tin-plated?\u003c\/strong\u003e Tin-plated connector blades on the 5138 resist corrosion, which helps maintain a reliable connection in the marine environment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many fuses come in a package?\u003c\/strong\u003e The 5138 is sold in a retail pack of 1, so each package contains a single 30 amp MAXI fuse.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAre other amperage ratings available in this same fuse line?\u003c\/strong\u003e Yes, Blue Sea Systems offers this same MAXI fuse style in other amperage ratings including 40A, 50A, 60A, 70A, and 80A versions for higher-draw circuits.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat circuits is a 30 amp MAXI fuse typically used for?\u003c\/strong\u003e A 30 amp MAXI fuse like the 5138 is commonly used for boat circuits requiring MAXI-style overcurrent protection, such as battery or accessory feeds rated at that amperage.\u003c\/p\u003e","brand":"Blue Sea Systems","offers":[{"title":"Default Title","offer_id":48989502832859,"sku":"BSS-5138","price":5.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/5138.jpg?v=1784507515","url":"https:\/\/www.goodvibesmarina.com\/products\/blue-sea-systems-5138-maxi-fuse-30a-blade-style-marine-fuse-with-tin-plated-blades","provider":"Good Vibes Marina","version":"1.0","type":"link"}
