3404.2465.11

Fuses serve a vital safety role in electrical systems, by protecting the circuits against excessive currents. In the 3404.2465.11 series manufactured by Littelfuse, fast-acting fuses are provided with electrical ratings up to 10A, 300V UL, CSA, and VDE for braid and sliding blade type (KDD). This series is ideal for applications such as powering up a laptop computer, home appliance safety circuitry, and automotive electrical systems.

Working Principle

When the current in a circuit exceeds the fuse rating, the links which form a bridge within the fuse will heat up rapidly until they melt. This opens the circuit breaking the passage of current. The current is interruped, but the materials that conform to the fuse will continue to act as an insulation barrier protecting against the buildup of possible electric shocks.

Features

• UL Recognized - File # E96734 (3404.2465.11)
• Excellent temperature and moisture stability
• High breaking capacity
• Low contact resistance design
• Mechanically compatible
• High repeatability

Design Considerations

Fuses come in various physical and electrical configurations. Most importantly, the fuse must be rated at a value that is higher than the expected maximum current in the circuit it is placed in. Typically, the rated current of the fuses should be 1.5times to 2 times greater than the maximum current in the circuit. In addition, the size of the fuse body should be considered to ensure that it will fit in the given physical space for mounting.

Applications

The 3404.2465.11 series of fuses are generally suitable for safety purpose in medium-current low-voltage circuits. These fuses, in particular can be used in applications such as powering up computers or home appliances, automotive security and safety systems, and other similar applications.

Conclusion

The 3404.2465.11 series of fuses provide the ideal solution for applications requiring high-current, low-voltage protection. With features such as UL recognition, excellent temperature and moisture stability, and low contact resistance design, this series from Littelfuse proves to be a reliable and safe solution.
