  • 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
