Bussmann FWH-200B

Bussmann FWH-200B

Overview

The Bussmann FWH-200B is a high speed cylindrical fuse engineered for semiconductor protection in demanding industrial applications. Rated at 200 A with a voltage capacity of 500 V AC/DC, it delivers reliable overcurrent protection for DC common bus systems, power converters, rectifiers, and variable speed drives.

With a 200 kA breaking capacity and a Class aR utilization category, the FWH-200B ensures safe interruption of fault currents while minimizing energy let-through. Its ceramic body and stud-mount blade connections provide durability and secure installation in harsh environments.
