This bolt-down fuse adopts bolt-on stud mounting with high-temperature PPS + ceramic composite housing, delivering reliable overload and short-circuit protection for energy storage battery systems, supercapacitors, new energy vehicles and industrial DC busbars. With stable arc-extinction performance and fast clearing speed, this bolt-down fuse effectively protects power semiconductor devices from surge damage.<\/p>\n<h2>Key Features of Bolt-Down Fuse ANL-B150BSF51<\/h2>\n<ul>\n<li>Rated DC voltage: 150V; current range: 100A to 700A<\/li>\n<li>20kA high short-circuit breaking capacity, adaptable to circuits with L\/R \u2264 25ms<\/li>\n<li>High-temperature PPS + ceramic composite housing for excellent arc quenching<\/li>\n<li>Compliant with UL248-1 safety standard<\/li>\n<li>Operating temperature range: -40\u2103 to +125\u2103, suitable for harsh outdoor and vehicle environments<\/li>\n<li>Compact bolt-down structure for easy installation on copper busbars<\/li>\n<\/ul>\n<p>Under 20kA short-circuit conditions, this bolt-down fuse reduces both melting and arcing energy for faster breaking speed and less impact on power devices. Its overload threshold and voltage drop remain stable, and long-term current-carrying capacity is not affected by short-circuit levels.<\/p>\n<h2>Main Electrical Specifications<\/h2>\n<table style=\"border-collapse: collapse;
