Fuse Characteristics: CLASS_CC
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.
| fuse class | record id | amp rating max (A) | amp rating min (A) | application | conventional fusing current factor (dimensionless) | conventional nonfusing current factor (dimensionless) | current limiting | dimensions ferrule blade | fuse type | interrupting rating kA ac (kA) | notes | rejection feature | time delay | ul standard | voltage rating V (V) |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| CLASS_CC | cc_600v_fast | 30 | 0.1 | Class CC 600VAC 0.1-30A only; fastest-acting smallest body current-limiting fuse; rejection feature on ferrule body prevents larger fuses from being installed; common in industrial control panels | 1.35 | 0.9 | current_limiting | 1.5in_x_0.41in_ferrule | CC | 200 | Class CC limited to 30A maximum; very high current limitation; often used in control circuits 120/240/480VAC; CD class extends 35-60A range; 200kA interrupting | rejection_ferrule_1.5in_tube | fast_acting | UL_248-4 | 600 |
| CLASS_CC | cc_600v_td | 30 | 0.1 | Time-delay Class CC; dual element; 10s at 500%; used for small motor branch circuits in IEC-style machines; NEC 430.52 compliant at 175% TD setting | 1.35 | 1.1 | current_limiting | 1.5in_x_0.41in_ferrule | CC_time_delay | 200 | Bussmann LP-CC Littelfuse KLDR; 10s minimum carry at 500% rated current; common choice for motor starters and IEC-style disconnect switches | rejection_ferrule_1.5in_tube | time_delay | UL_248-4 | 600 |
