155.0892.6301 Circuit Protection

155.0892.6301 is a type of electrical specialty fuses that can provide protection for circuit from over-current or short-circuit. It is widely used in many areas and the working principle vary depending on the application.

A 155.0892.6301 fuse is composed of fusible body, connecting pin and a heat-sensitive element. The fusible body can be made of metal, ceramic, plastic or a mixture of various powder materials, depending on the application and current rating. The connecting pin is fixed on the end of the fusible body and it is used for connecting the fuse to the circuit. The heat-sensitive element is the most important part of the fuse, which can detect over-currents or short-circuits to protect the circuit components from excessive temperature or physical damage.

It can be used in many fields including but not limited to household appliances, computers, automotive, radio or television sets, electrical tools and industrial equipment. Its application can be divided into two major categories according to the operation principle.

The first type is known as the constant current fuse. It works on the principle of heat transfer. When an over-current is detected, the heat-sensitive element heats up and melts the connecting pin, thus opening the circuit. If the circuit is short-circuited, the current flowing in the circuit will cause further heating of the fuse wire, thus melting the fuse and thus opening the circuit. So this type of fuse will protect the circuit components from burning due to over-current or short-circuit.

The second type is the thermal-magnetic fuse, which works on the principle of heat and magnetism. It has two parts, a heat-sensitive element and a magnet. The heat-sensitive element can detect over-currents or short-circuits and produce heat. The magnet will sense the increase in temperature and will pull the connecting pin, thus opening the circuit. So this type of fuse can protect the circuit components from excessive temperature or physical damage due to over-current or short-circuits.

In conclusion, 155.0892.6301 is a type of electrical specialty fuses that provide protection for circuit from over-current or short-circuit. It is widely used in many areas and the working principle varies depending on the application. It can be divided into two major categories according to the operation principle, the constant current fuse and the thermal-magnetic type fuse.
