Littelfuse BMZF Battery Mount ZCASE® Forged Fuse Holders feature a forged-brass design that is rugged and well-suited for heavy-duty applications. Littelfuse BMZF Fuse Holders provide an integrated battery clamp that allows for high-current fusing to be mounted directly to a post-style battery terminal without additional mounting hardware. BMZF features a cost-effive, compact design that eliminates additional cables, separate high-current fuse holders, and the required labor to assemble and install traditional fuse holders into crowded spaces. Littelfuse BMZF series accepts Littelfuse M10 ZCASE fuses that are available in ratings from 80A to 600A and that have characteristics similar to those of the MEGA fuse. For fuses rated 80A to 250A, circuits are protected from damage due to prolonged overload current conditions. At ratings from 300A to 600A, the ZCASE acts as a short circuit protector, allowing high inrush currents but protecting from system faults.
