Class T fuses are the type most often recommended by inverter manufacturers because of their high speed response to short circuits, making this block a common choice for protecting inverter feed cables and other heavy-gauge circuits up to 320 amps at up to 160 volts DC.\u003c\/p\u003e\u003cp\u003eThe block uses a four stud design that provides ample access around the connecting stud, so large cable lugs can be installed without obstruction from the fuse itself. Stainless steel studs resist corrosion and hold up to high torque, while one-piece stainless flange nuts keep connections safe and secure. The stud design ensures the fuse mounts securely even under high heat, and the base is rated UL 94-V0 for resistance to high heat. A clear insulating cover satisfies ABYC\/USCG insulation requirements, and cover breakouts allow wire to exit in any direction for flexible installation. Terminal studs are 3\/8 inch-16 and accept ring terminals for wire up to 4\/0 AWG. Note that the Class T fuse itself is sold separately.\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 5502\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 320 Amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 160 Volts DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Stud Size:\u003c\/strong\u003e 3\/8 inch-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Size Capacity:\u003c\/strong\u003e Up to 4\/0 AWG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Panel Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Material Rating:\u003c\/strong\u003e UL 94-V0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 3 x 9 x 7.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e Four stud design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCover:\u003c\/strong\u003e Insulating cover, satisfies ABYC\/USCG insulation requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the amp rating of the Blue Sea Systems 5502 fuse block?\u003c\/strong\u003e The Blue Sea Systems 5502 is rated for 320 amps and is designed to accept Class T fuses in that range.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 5502 fuse block include the fuse?\u003c\/strong\u003e No, the Class T fuse is sold separately from the 5502 fuse block.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat voltage is the 5502 fuse block rated for?\u003c\/strong\u003e The 5502 is rated for use on DC systems up to 160 volts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat wire size can I use with the 5502 fuse block?\u003c\/strong\u003e The 5502 has 3\/8 inch-16 terminal studs that accept ring terminals for wire up to 4\/0 AWG.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy do inverter manufacturers recommend a Class T fuse block like the 5502?\u003c\/strong\u003e Class T fuses provide a high speed response to short circuits, which is why the 5502 is the type most often recommended by inverter manufacturers for protecting heavy-gauge inverter cabling.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the four stud design on the 5502 for?\u003c\/strong\u003e The four stud design on the Blue Sea Systems 5502 gives ample access around the connecting stud so large cable lugs can be installed without the fuse getting in the way.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 5502 fuse block covered for safety?\u003c\/strong\u003e Yes, the 5502 includes a clear insulating cover that satisfies ABYC\/USCG insulation requirements, with breakouts that allow wire to exit in any direction.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material are the studs and hardware made from on the 5502?\u003c\/strong\u003e The 5502 uses stainless steel studs for corrosion and torque resistance, along with one-piece stainless flange nuts for secure connections.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Blue Sea Systems 5502 fuse block weigh?\u003c\/strong\u003e The 5502 weighs 1.1 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 5502 fuse block?\u003c\/strong\u003e The 5502 measures 3 x 9 x 7.25 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the 5502 fuse block mounted?\u003c\/strong\u003e The 5502 is a panel mount fuse block.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the base of the 5502 fuse block rated for?\u003c\/strong\u003e The base of the 5502 is rated UL 94-V0 for resistance to high heat.\u003c\/p\u003e","brand":"Blue Sea Systems","offers":[{"title":"Default Title","offer_id":48989504471259,"sku":"BSS-5502","price":61.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/5502.jpg?v=1784507110","url":"https:\/\/www.goodvibesmarina.com\/products\/blue-sea-systems-5502-class-t-fuse-block-225-400a-160v-dc-marine-inverter-fuse-holder-with-3-8-16-studs","provider":"Good Vibes Marina","version":"1.0","type":"link"}
