0157004.DRT

The 0157004.DRT application field and working principle pertain to fuses.

A fuse is a type of electrical device used to help protect appliances and equipment from excessive voltage and current, thereby preventing a fire, electric shock, and equipment damage. By utilizing the principle of “melting alloy”, when the current running through a circuit exceeds a certain value, the built-in metal melting wire in the fuse can be short-circuited to achieve the purpose of protection. The so-called "0157004.DRT" refers to a type of fuses.

In general, a 0157004.DRT fuse contains a metal alloy or two layers of metal rods with different melting points. It will be connected between the circuit and the power supply, and its main function is over-current protection. When the current flowing through the wire exceeds the normal operating range, the metal melting wire melts due to excessive heat generated by the current, so that the circuit between the two metal rods is cut off and the current is broken off. Therefore, the electric appliance is not damaged due to excessive current, and the overall safety of the entire system is ensured.

At the same time, in order to ensure the safety of people and property, the 0157004.DRT fuses must be temperature-resistant and anti-aging, retain insulation performance when operating at high temperatures, be waterproof and oil-resistant, and keep good contact performance and low contact resistance without oxidation. In addition, in order to meet different needs, a variety of specifications and models of 0157004.DRT fuses are available.

The 0157004.DRT fuses are mainly used in home appliances, as well as in small motors, transformers, electronic circuits, and industrial electrical circuits to protect against overloads, short circuits, or loss of zeroes. This makes the 0157004.DRT fuse an indispensable part of various electrical devices.
