Cooper Bussmann HVU-2 High Voltage Fuse Assembly

The HVU-2 High Voltage Fuse Assembly from Bussmann (Cooper Bussmann, now Eaton Bussmann) is a replaceable fuse cartridge rated at 2 A and 5 kV AC, designed to protect high‑voltage circuits in industrial power distribution and control applications. It is intended for use with Bussmann HVU fuse blocks and assemblies, serving as a dedicated high‑voltage protection link where standard low‑voltage fuses would be unsuitable. As part of the HVU family of high‑voltage fuses, the HVU‑2 reflects Bussmann’s approach to reliable protection in equipment operating at elevated voltages, with a compact cartridge form factor that fits into compatible HVU holders across industrial installations. When selecting a high‑voltage fuse for an HVU application, engineers align the 2 A current rating with the protected circuit’s fault-current characteristics and ensure the 5 kV AC voltage rating matches the service voltage. The HVU‑2 is a recognized option in distributors’ catalogs and is listed under the Cooper Bussmann line, representing a standard, commercially available high‑voltage fuse cartridge for applications requiring precise high‑voltage protection.
