Bussmann IXL70F150 Semiconductor Fuse

IXL70F150 is a Bussmann/Eaton high-speed semiconductor fuse designed for board-mount protection in power-electronic equipment. It is rated for 150 A with a voltage rating of 700 V AC and 700 V DC, and it comes in a compact 39 x 129 mm package suitable for fuse-board installations; the device is UL-listed for semiconductor protection. This fuse interrupts fault currents quickly to protect downstream semiconductor devices in systems up to 700 V, making it a common choice in high‑voltage power‑electronic applications where precise protection coordination with other protective devices matters. Some listings describe a variant with an integral indicator to show trip status, aiding diagnostics in complex assemblies.
