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.
