Bussmann KBH-150 Fuses

The Bussmann KBH-150 fuse is a semiconductor protection device in Eaton’s Bussmann line, engineered to guard high-current power electronics by interrupting fault currents in a controlled, rapid manner and thereby minimizing damage to transistors, diodes, transformers, and other downstream components. Common applications include protection for rectifier modules, inverters, motor drives, switching power supplies, and other power-conversion circuits where fast fault clearing and reliability are critical for maintaining uptime in industrial, telecom, and energy-storage systems. As a member of the KBH family, the device emphasizes consistent form factor and predictable interruption behavior, enabling engineers to design protection schemes with interchangeable components across multiple Bussmann platforms and to simplify spare-parts inventories. The KBH-150 is designed to respond to overcurrent events in semiconductor loads without excessive nuisance tripping during normal transients, helping safeguard expensive power electronics while supporting safe disconnection from the source during faults.
