Littelfuse® L50S series high speed fuses are designed to protect today's equipment and systems and are manufactured with Littelfuse® developed technology that sets tomorrow's standards for accuracy, consistent quality, reliability and predictable performance. Littelfuse® engineers have redefined high speed fuse technology by using advanced metallurgical, polymer and materials research, mathematical modeling and computerized statistical analysis.
- Applications
- Features
| For supplementary protection of semiconducting devices such as silicon controlled rectifiers (SCR's), diodes, thyristors, triacs, transistors and similar solid state devices, power equipment including variable speed drives, power rectifiers, UPS systems, DC power supplies and in a wide range of electronic equipment, electrical and industrial applications |
| 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 |
