Fuseholders are key components in electrical systems, designed to protect circuits from damage by excessive current. The LJ60030AC fuseholder is a heavy-duty holder for use with MIL-Spec Fuses, providing secondary protection for Aircraft power systems and other electrical systems. In this article, we will discuss the application fields and working principle of the LJ60030AC fuseholder.

Application Fields

The LJ60030AC fuseholder is designed to accept and hold MIL-fuses in circuits located in aircraft and other high-voltage industrial applications. This holder is compliant with MIL-PRF-5404F Type 2A/2B and is qualified to Mil-STD-202F test standard. The LJ60030AC is especially suitable for high-vibration environments, such as those found in aircraft power systems. The holder’s solid-state technology eliminates the possibility of accidental arcing of fuel, aiding in the prevention of explosive fuel mixtures. Additionally, the holder can accept and hold both standard and custom designs MIL-fuses, which makes the LJ60030AC an ideal choice for customizing a protective circuit or power system.

Working Principle

The LJ60030AC works according to Ohm’s law. It can limit the current that flows through the circuit when a short circuit or overload occurs. The fuse operates on the principle of Electrical Thermodynamics. When the current exceeds the rating of the fuse, the thermal resistance of the fuse quickly melts the contact points. This dissipation of heat due to the current rapidly alters the resistance of the conductor, allowing the current to flow and protect the circuit from damage.

The LJ60030AC fuseholder is designed with Crimp electrical connections, making installation and removal easier and more efficient. The holder also features a rugged glass-filled thermoplastic body and a Tin-plated tube to increase mechanical strength and protection against corrosion. To ensure safety and reliability, the holder is equipped with redundant contacts designed to reduce the possibility of accidental contact between the fuse and its enclosure. Finally, the holder comes with a vented cover so that the heat produced during operation can escape more efficiently.

Conclusion

The LJ60030AC fuseholder is a reliable and highly-resistant holder for use in MIL-spec fused circuits. The holder’s robust construction and redundant contacts make it ideal for use in aircraft power systems and other industrial applications. The holder works according to Ohm’s law and can limit the flow of current when an overload or short circuit occurs, protecting the system from damage. With its Crimp electrical connections and vented cover, the LJ60030AC ensures operational safety and reliability.
