Bussmann KAB-70 Fuses

Bussmann TRON KAB-70 fuses are 70-amp, high-speed rectifier fuses designed for fast, reliable protection in power conversion and rectifier circuits. These cartridge-style fuses are part of Bussmann’s TRON semiconductor fuse family, typically configured in North American style panel installations for quick replacement in demanding electronic power systems. A closely related model in the same family, the KAC-70, is specified at 70 A with a 600 V AC rating and an interrupt capacity of 200 kAIC, underscoring the level of fault protection these fuses provide in high-current rectifier and switching applications. When used in power supplies, inverters, or other high‑current loads, the KAB-70 family aims to combine fast protection with robust endurance, helping to prevent damage from short circuits while tolerating normal transient events.
