Industrial 800A ANL Fuse Block, Open Air Heavy Duty Fuse Holder

Unleash Extreme Power with Industrial-Grade Circuit Protection When you are pushing massive currents through a 48V off-grid solar array, a heavy-duty marine battery bank, or a commercial power distribution system, standard plastic fuse holders simply cannot survive. The Weasch Industrial 800A Open-Air Fuse Block is purpose-built from the ground up to handle extreme electrical loads and brutal environments without breaking a sweat. Heat-Proof Bakelite Foundation Heat is the enemy of high-amperage circuits. That is why we abandoned standard thermoplastics and engineered our base entirely from premium Black Bakelite. As a heavy-duty thermosetting material, Bakelite provides unparalleled thermal stability. It will not melt, warp, or deform even under the continuous heat generated by massive 800A loads. 304 Stainless Steel Hardware A fuse block is only as good as its connections. Every single piece of metal hardware on this block—including the bolts, hex nuts, spring lock washers, and spacers—is precision-machined from genuine 304 Stainless Steel. This guarantees a rock-solid, zero-rust, and corrosion-proof connection that thrives in harsh saltwater marine and RV environments. Furthermore, the entire assembly is strictly RoHS Certified, ensuring eco-friendly and safe integration. Compact & Universal Design Designed to accommodate standard bolt-on ANL, CNN, and CNL fuses , this block features a precise 62.00mm center-to-center stud spacing. Despite its monstrous 800A DC48V rating , it maintains an ultra-compact 86.50mm overall length, making it the perfect space-saving solution for tight electrical panels and dedicated battery compartments.

• 【800A EXTREME CURRENT CAPACITY】Engineered for the most demanding power setups. Rated for up to DC48V 800A and AC220V 800A. This block is the ultimate foundation for massive battery banks, heavy-duty alternators, and 48V off-grid solar inverters where standard holders would fail
• 【THERMAL-PROOF BAKELITE & OPEN-AIR DESIGN】Built with an industrial-grade Bakelite base. Unlike standard thermoplastic blocks that melt under high continuous loads, Bakelite is a thermosetting material that withstands extreme heat without deforming. The purposeful open-air architecture ensures maximum passive heat dissipation for 800A currents
• 【304 STAINLESS STEEL & RoHS CERTIFIED】True marine-grade reliability and strict safety compliance. Every piece of hardware is forged from premium 304 Stainless Steel for a rust connection. Furthermore, the entire assembly is fully RoHS Certified, ensuring it is free from hazardous materials and completely safe for enclosed RV or marine environments
• 【COMPACT YET POWERFUL】Despite its massive 800A rating, the block features a highly compact footprint (86.50mm overall length) ideal for tight electrical panels. It features a standard 62.00mm center-to-center stud spacing to flawlessly accommodate all bolt-on ANL fuse
• 【PROFESSIONAL INTEGRATION】Designed for serious DIYers and professional electricians. Due to its open-air, extreme-amperage design, we highly recommend installing this block inside an enclosed electrical panel or dedicated battery compartment. (Please Note: ANL Fuse NOT included)
