Fuse Characteristics: CLASS_G
Fuse time-current characteristics, voltage ratings, interrupting capacity, and current-limiting classification by fuse class. Covers UL 248 classes (J, RK1, RK5, CC, T, L, G, H, K) and IEC 60269 types (gG, gM, aR, aM). Includes melting and clearing I2t let-through energy ranges, peak let-through current, conventional fusing/non-fusing current factors, rejection feature type, and application guidance.

|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| CLASS_G | g_480v | 60 | 0.1 | Class G 480VAC 0.1-60A; glass tube body with rejection feature; used in lighting panels small branch circuits; lower interrupting capacity 100kA vs other CL classes; tube diameter selected by current rating | 1.35 | 0.9 | current_limiting | glass_tube_13_32in_or_9_16in | G | 100 | Class G limited to 60A max and 480V; tube diameter 13/32in (up to 15A) or 9/16in (16-60A); lower interrupting capacity 100kA; rejection by tube size prevents Class CC or midget substitution | rejection_glass_tube_size | fast_acting | UL_248-5 | 480 |
