3412.0115.24 Circuit Protection

Fuses

A fuse is a type of electrical component designed to protect an electrical circuit against overcurrent, overvoltage or short circuit by providing a connection point that temporarily disrupts the flow of current when it exceeds a certain amperage value. Fuses are widely used in industrial, commercial, and residential applications. Amongst the most common types of fuses are air-break fuses, cartridge fuses, plug fuses, and surface mount fuses.

3412.0115.24 Application Field and Working Principle

The 3412.0115.24 Fuse is a two-way circuit-breaker designed to protect home appliances from overcurrent, overvoltage, and short circuit. Unlike air-break or cartridge fuses, the 3412.0115.24 Fuse is designed to be self-resetting after an electrical surge. This means that once the fuse trips and the current is cut off, it will automatically reset itself, allowing the appliance to resume working in normal conditions.

The 3412.0115.24 Fuse is primarily used on medium-sized household appliances such as TVs, DVD players, and microwaves. It is also used in light industrial applications, such as small-scale manufacturing lines that contain many small electric motors. The fuse can also be used on medical electronic equipment, such as home blood pressure machines.

The 3412.0115.24 Fuse works by having two elements, an inner and an outer element, housed in a ceramic body. When current flows through the fuse, the inner element heats up and expands, eventually breaking contact between the two elements and effectively cutting off the flow of electricity. When the surge is over, the inner element cools and contracts, allowing the two elements to come back into contact and resume the flow of electricity. This process allows the fuse to reset itself and protect the circuit from further damage.

In addition to providing protection against overcurrent, the fuse also acts as a visual indicator. When the fuse trips, the opening of the ceramic body is visible, allowing users to identify the cause of the electrical outage simply by inspecting the fuse.

The 3412.0115.24 Fuse is a versatile and reliable safety device that provides essential protection in industrial and domestic applications. By detecting overcurrent quickly and providing a self-resetting protection system, the fuse ensures that the appliance is not harmed by the sudden surge.
