eaton:country/north-america/us Thanks Dave, I was looking for the correct calculation to determine the fuse size. The two fuses are connected in series, and are coordinated so that the current-limiting fuse operates only upon internal equipment failure. The T Fuse has a small footprint, roughly 1/3 the size of a comparable Class R fuse. ELSP:
