Bussmann WFFH0160A Fuse

Bussmann WFFH0160A is a high-voltage, 3.6 kV AC, 160 A cartridge fuse from Eaton’s Bussmann series, engineered for medium‑voltage motor protection and motor‑starter circuits. The glass‑body, high‑rupturing‑capacity (HRC) fuse is a bolt‑on cartridge device with a 76 mm × 356 mm footprint and is non‑indicating, so it shows no built‑in fault indicator. It provides up to 50 kA breaking capacity at rated voltage, ensuring rapid interruption of severe faults in HV motor feeders, switchgear, and control circuits. Used where motors operate at 3.6 kV, this fuse links with Bussmann MV protection schemes to guard against overcurrents while tolerating normal starting transients. The WFFH0160A’s design emphasizes visibility of the fuse element through its glass body and compatibility with standard Bussmann high‑voltage protection hardware, making it a precise replacement for existing 3.6 kV, 160 A motor‑protect fuses in appropriate equipment. Typical applications include protecting motors connected to 3.6 kV distribution or motor feeders in industrial facilities.
