- 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
- 100 kA RMS, 20 kA interrupt rating
