RS PRO 5x20mm kārtridžu ātri ~ lēni izpūsti drošinātāji ar svinu

Funkcija, material and characteristics of 5x20mm Cartridge Fast~slow Blown Fuses: The origin of the name of the fuse is a vivid reflection of its function and value.

Drošinātājs: refers to the protected electrical, which plays the role of overcurrent safety protection and risk avoidance. It is generally presented in the form of wire or strip, so it is called a fuse.

In terms of material, fuses are generally of two types: pure metal and alloy. The fuses we usually use are generally lead-antimony alloy, aluminum-magnesium alloy, gold wire, utt..

No matter what type of fuse, it plays the role of overload protection under the influence of these two factors and characteristics.

The first characteristic is resistivity. When the current is large, it can generate a large amount of heat in a short time, which promotes fuse protection.

The second characteristic is the melting point, which needs to be lower than the temperature that the protected electrical appliances and circuits can withstand to fuse.
