Heavy-Duty ANL Fuse Block with Cover, 300A Capacity Fuse Holder

Build Your Ultimate Line of Defense with Professional-Grade Circuit ProtectionWhen it comes to wiring high-power inverters, marine battery banks, or competition-level car audio systems, cutting corners on your fuse block is not an option. The Weasch Heavy-Duty 300A ANL Fuse Block is meticulously engineered from the ground up to provide a rock-solid, zero-voltage-drop connection for your most demanding 12V, 24V, and 32V DC electrical systems.Engineered with Uncompromising Materials Unlike cheap, standard fuse holders that use standard plastics, our base is constructed from an industrial-grade PA+GF (Polyamide + Glass Fiber) blend, paired with a transparent PC (Polycarbonate) safety shield. Both components strictly adhere to the UL 94 V-0 flame-retardant standard. This means in the event of an extreme electrical surge, the block will self-extinguish and safely contain the heat, rather than melting or fueling a fire.Maximum Conductivity, Zero Bottlenecks Power delivery is everything. We upgraded the hardware to heavy-duty carbon steel featuring a premium imitation-gold/nickel plating. This advanced plating not only resists marine salt spray and rust but guarantees minimal electrical resistance. The included M8 (approx. 5/16") threaded studs, along with carbon steel spring lock washers and hex nuts, ensure your terminal lugs stay securely clamped even under severe road or engine vibration.Precision Fit & Pro-Level Installation Designed for universal compatibility, this holder features a precise 61.5mm (approx. 2.4") center-to-center stud spacing to seamlessly accept any standard bolt-on ANL fuse. The transparent snap-on cover allows for instant visual inspection of the fuse status without exposing live wires.

• 【FLAME-RETARDANT CONSTRUCTION】Safety is engineered into every detail. Both the rugged PA+GF (Polyamide + Glass Fiber) base and the transparent PC (Polycarbonate) cover are manufactured to the strict 94 V-0 flame-retardant standard. This ensures the holder will self-extinguish and will not melt or feed a fire under severe electrical faults
• 【CLEAR SAFETY SHIELD】Features a transparent PC cover that allows for instant visual inspection of the fuse status without disassembly. This shield effectively insulates live connections, preventing disastrous short circuits caused by dropped wrenches. Recommended mounting torque: 5Nm. (Please Note: ANL Fuse is NOT included)
• 【300A CAPACITY】Rated for DC 32V 300A and AC 220V 300A. Designed specifically for heavy-gauge cables requiring ultra-high current protection. It provides a rock-solid foundation for battery and alternator connections in 12V 24V and 32V RVs, marine vessels, and custom automotive builds
• 【M8 THREADED STUDS】Take the guesswork out of your installation. This block features universal M8 (approx. 5/16") threaded studs, complete with carbon steel hex nuts and spring lock washers. The imitation-gold/nickel plating guarantees maximum conductivity while preventing nuts from loosening due to engine or road vibration
• 【UNIVERSAL ANL FUSE】Engineered for a perfect fit. Features a standard 61.5mm (approx. 2.4") center-to-center stud spacing to seamlessly accommodate all standard bolt-on ANL fuses, 137.5mm mounting hole distance. Perfect for DIY off-grid solar enthusiasts, professional automotive audio installers, and marine electricians
