- Applications
- Features
| Protection of Semiconductors |
| Very-Fast Acting |
| Reliable interruption of all overcurrents meets present and future system requirements |
| Extremely current limiting - low i2t and peak let-through currents meet most semiconductor requirements |
| Low watt losses - means less heating and power consumption in circuit |
| Controlled transient overvoltages - all circuits are subject to transient overvoltages during fault current interruption |
| These transient overvoltages (arc voltages) start when fuse links melt or circuit breaker contacts part and subside when circuit is interrupted |
| Semiconductors are very sensitive to overvoltages |
| Littelfuse® semiconductor fuse designs keep transient overvoltages to low levels and help reduce semiconductor failure |
| May be used wherever extremely fast acting, current limiting fuses with no time delay are required |
| VAC 100 kA RMS VDC, 20 kA interrupt rating |
