TR225R - 225 Amp Fuse Description
TR225R - 225 Amp Fuse
When you're protecting a high-current electrical system, choosing the right fuse is about more than matching the amp rating. Motors need room for normal startup current. Transformers can draw a substantial surge when energized. When a serious short circuit occurs, the protective device must be able to interrupt the available fault current. The Mersen TR225R 225 Amp Class RK5 Time-Delay Fuse is designed to address these demands in compatible industrial and commercial electrical applications.
