161.475200B

Fuses are a type of electrical component used to protect circuits from damage due to overvoltage, overload, or short circuit conditions. The purpose of a fuse is to interrupt the circuit in case of a dangerous electrical situation, thus preventing electrical fire or other damage. The 161.475200B is a glass tube-style fuse used for high-voltage applications.

Construction

The 161.475200B is a cylindrically shaped, glass tube fuse with an integral kernel of fine metal particles or wire. The metal particles, or fusible element, is embedded in a heat-conductive body which is completely sealed in the glass tube. The outside diameter is 5.5mm, with a length of 32.5mm and an amperage rating of 40A. Fuses are color-coded to indicate the amperage rating.

Working Principle

The working principle of the 161.475200B is fairly simple. In the event of an overload or short circuit, the metal particles or fusible element embedded in the center of the fuse will heat up rapidly. This results in an increase in resistance in the circuit. The more current that passes through the circuit, the hotter the metal particles will get and the greater the resistance.

As the temperature of the metal particles increases, so does the resistance and the voltage will eventually drop to zero. When the voltage drops to zero, the arc created by the metal particles is extinguished and the circuit is interrupted. This prevents any further current from flowing through the circuit and thus preventing any damage from occurring.

Application Fields

161.475200B fuses are typically used in high-voltage applications where protection against power surges, overloads, or short circuits is necessary. They are commonly used in high-voltage power supplies, industrial motors, electrical automotive systems, and electrical heating systems. These fuses are also ideal for equipment that requires low voltage but high current or power ratings.

Advantages

One of the advantages of 161.475200B fuses is that they are relatively inexpensive compared to other types of fuses. They are also fairly easy to install and maintain. In addition, they are designed to safely trip in the event of a dangerous electric situation and thus preventing any electrical fire or other damage.

Fuses are also much safer than circuit breakers as they can trip much faster than circuit breakers and are designed to trip in the event of an overload or short circuit condition. This ensures that the circuit is protected even in the event of an unexpected power surge.
