Fuses are highly important pieces of safety equipment used in a variety of electrical services to create an open circuit when an excess current flows and protect both the person and the equipment connected. The ABC-20-R is a type of mid-range electric fuse commonly used. This article will look into the application field and working principle of the ABC-20-R.

The ABC-20-R is popular due to its wide range of functionalities and applications. It is suitable for use in home and commercial buildings, on industrial equipment, in machinery, sub panels, and in marine vessels. It is also compatible with a variety of amperage scores, ranging from 1 Amp to 60 Amp, making it suitable for many of small and medium sized systems. Being UL listed with VDE, CSA, and TUV certifications, this fuse adheres to the highest standards of safety protocols.

The ABC-20-R comes in a variety of sizes that accommodate the different sorts of appliances and devices. These sizes include 10x38mm and 14x51mm tube fuses, 0.5x15mm fast-blow fuses, and 1.25x30 millimeter slow-blow fuses. It is an ideal replacement for older Edison fuses.

The ABC-20-R consists of an inner conductor that connects two metal ends to the end connections. The inner conductor forms a metal bridge between the insulation plates, the back of which is filled with a conductive material known as fuse wire. The amperage rating of the fuse affects the size of the metal bridge and the wire used. For example, a 10 Amp rated fuse will be made with thicker bridge material and a lighter fuse wire than a 30 Amp rated fuse.

When an overcurrent occurs, the heat generated by the excessive current causes the fuse wire to melt, breaking the connection between the metal ends and the inner conductor. This interrupts the flow of current from the source to the appliance, preventing the device from becoming damaged by an overcurrent. As the fuse wire has been melted, the fuse must be replaced in order to restore normal operation.

In conclusion, the ABC-20-R is a mid-range electric fuse which is suitable for use in a variety of applications. It is popular because of its wide range of functionalities and applications, as well as high safety standards such as TUV and UL certification. Its working principle is also quite simple, as the excessive current causes the fuse wire to melt, breaking the circuit and preventing damage from occurring.
