Cooper-Bussmann IXL770F250 Semiconductor Fuse

Cooper Bussmann IXL70F250 semiconductor fuse is a high-speed protective device rated for 250 A with a maximum 700 VAC and 700 V DC operating voltage, designed to interrupt fault currents rapidly in power-electronic circuits and thereby limit damage to switching devices and power conversion stages. As a member of Bussmann's IEC High Speed semiconductor fuse family, the IXL70F250 is specified for fast fault clearance in applications where dense switching, high dv/dt, and sensitive semiconductor devices need precise protection, such as DC links in inverters, motor drives, and power-supply modules. The 250 A current rating and 700 V rating make it well suited for protective roles in industrial equipment that handles significant current and voltage, helping to protect enclosures, boards, and wiring harnesses while enabling selective coordination with other protection devices in a system. Typical use cases include industrial power supplies, variable-frequency drives, solar inverters, rectifier modules, and telecom power equipment, where fast-acting protection against short circuits can prevent cascade failures and extend the life of expensive semiconductors.
