Bussmann Series High Speed Fuses are current-limiting protective devices designed for the semiconductor and power electronics industry. These fuse-links, also known as ultra-rapid fuses or semiconductor fuses, are engineered to provide superior short-circuit protection for diodes, thyristors, IGBTs, and other power electronic components. Available in a wide range of amperages from 20 A to 1750 A and voltage ratings from 550 V to 2000 V AC, they come in various physical sizes including DIN 000 and size 3 formats. The range includes both aR (partial range) and gR (full range) characteristics, with single indicator functionality for quick visual identification of blown fuses. These high-speed fuses are characterized by their extremely low I²t values, ensuring minimal thermal and mechanical stress on protected components during fault conditions.
These high-speed fuses are essential in a variety of demanding industrial applications. They are commonly installed in variable frequency drives (VFDs), uninterruptible power supplies (UPS), rectifier units, DC power supplies, and soft starters. They also protect power converters, inverters for solar and wind energy systems, and welding equipment. In industrial automation, they safeguard servo drives and motor control centers. Their compact form factors allow for easy integration into existing fuse blocks and switchgear assemblies within control panels and distribution boards.
All Bussmann Series high-speed fuses comply with international standards including IEC 60269-4 and VDE 0636-4, ensuring global acceptance and reliability. They are fully compatible with standard fuse holders and bases from major manufacturers such as Eaton, Bussmann, and other leading brands. The aR and gR classifications guarantee appropriate coordination with upstream and downstream protective devices. These fuses are designed for use in AC circuits and are tested to meet rigorous performance criteria for semiconductor protection.
