Bussmann KBC175- Rectifier Fuse

The Bussmann KBC-175 North American style rectifier fuse is a fast-acting semiconductor fuse designed to protect diode bridges and other power‑electronics circuits. It is rated for 600 V AC operation and 175 A, with a high interrupt rating of about 200 kAIC, and it comes in a cartridge‑body, bolt‑down/stud‑mount format suitable for secure installation in rectifier assemblies. Some listings also specify a 1 kV DC rating for this series, highlighting suitability for DC link and high‑voltage rectifier applications. UL‑recognized and part of Bussmann’s high‑speed semiconductor fuse family, the KBC‑175 is commonly used to rapidly isolate faults in rectifier networks, protecting diodes and power‑electronic components in switch‑mode power supplies, welding power supplies, and large motor drives where fast overcurrent protection is required.
