Fuse Characteristics: CLASS T

t600 lt 0100A to t600 lt 0350A

Fuse time-current characteristics, voltage ratings, interrupting capacity, and current-limiting classification by fuse class (UL 248 and IEC 60269). Also includes per-rating let-through current (peak A) and I²t (A²s) data from IEEE Std 3004.3-2020 for arc-flash and short-circuit coordination studies, covering Classes RK1, RK5, J, T (300V/600V), L, CC, G, CF, CD, C, CA, CB, mine-duty, and semiconductor fuse voltage derating.
