Electrical components provide power to many aspects of life, as well as serving as a safety measure to protect against the hazards of electricity . Specialty fuses are among the most important of these components, and the LA130URD70LI0125 is an example of such a vehicular fuse. In order to properly explain the application field and working principle of the LA130URD70LI0125, the various characteristics, functions, and components of the fuse must be discussed.

Characteristics of the LA130URD70LI0125

The LA130URD70LI0125 is a midget vehicular fuse produced by Littelfuse Company, with a rating of 70A at 32 volts DC. Its UL listing feature means it can be used in many automotive applications, and it is compatible with any fuse panel. Additionally, the blade/blade construction ensures that it has a secure fit that is resistant to shock and vibration. Its Ni-plated tin blade terminals are corrosion resistant and provide high low-resistance electrical connections. The fuse measures 13/32" x 1 1/4" and weighs only 0.02 lbs.

Functions and Components of the LA130URD70LI0125

The primary function of the LA130URD70LI0125 is to protect electrical systems and circuits from being damaged by excessive current flow. It is placed in the electrical circuit and will blow or deactivate if the current flow exceeds the rated amperage level. This prevents burning out of components and eliminates the possibility of a fire hazard.

The actual component of a fuse consists of several pieces. The metal shell, or enclosure, is the outermost layer and provides protection and insulation to the internal fuse media. The fuse links are titanium or copper strips that connect the fuse ends together. The terminals connect the fuse to the circuit, and a safety window is usually included to alert the user to a blown fuse. Finally, the fuse media is the element that prevents current flow when heated, usually by a metal strip placed between the ends of the fuse.

Application Fields for the LA130URD70LI0125

The LA130URD70LI0125 is suitable for use in a wide variety of automotive applications. This includes fuse boxes, starter circuits, power windows, door locks, and heated window motors. The midget fuse is perfect for vehicles that require a high-amperage system and low voltage holds, such as generators, alternators, and starter switches. Additionally, the fuse may be used in other applications that involve low voltage, such as small fluid-control systems.

Working Principle of the LA130URD70LI0125

The LA130URD70LI0125 works on the principle of detecting when an excessive amount of current is passing through it and then deactivating. This prevents further damage from occurring to the equipment and thus acts as a protective measure. The actual fuse is constructed of a metal enclosure that holds the internal fuse links and media. When current flow exceeds the rated amperage, the fuse strip heats up and melts, thus breaking the connection between the two ends of the fuse. This prevents any further current flow and signals a blown fuse.

The LA130URD70LI0125 is an important example of specialty fuses that provide protection for a wide variety of electrical systems and circuits. Its UL listing allows it to be safely used in most automotive applications, and the blade/blade construction provides a secure fit that is resistant to shock and vibration. The working principle of the fuse is to detect excessive current flow and deactivate, thus preventing further damage to the equipment. The LA130URD70LI0125 provides a level of safety and protection that helps ensure the safe operation of many systems.
