Fuses are electrical devices that protect electrical systems from overcurrents and short circuits, and the 0674006.DRT4P is one of them. In terms of application field and working principle, each has its own uniqueness and this article provides a concise introduction.

Application field

The 0674006.DRT4P fuse is mainly used in transformer protection, motor circuits, distribution circuits and other parts of power systems. It is also suitable for the protection of household electrical appliances, electronic instruments, computer monitors and microwave ovens. In addition, its overload and short circuit protection capability far exceeds that of ordinary molded case circuit breakers, so it can provide more reliable protection.

Working principle

The 0674006.DRT4P fuse consists of two components, the main fuse element and the support. The main body of the fuse element is composed of an aluminum alloy strip or copper-coated ceramic, which is filled with an arc extinguishing material. Through this simple structure, when the circuit current exceeds the set current value, the fuse element melts quickly and the current is cut off.

At the same time, in order to prevent the fuse element from correcting the power supply when it melts, the support of the fuse element is filled with colophony, gypsum and other materials to absorb the arc and quickly reduce the current. When the current is lowered, the arc is extinguished and the circuit is opened.

Advantages

The 0674006.DRT4P fuse has many advantages. First of all, its high breaking capability can protect important lines and equipment from damage caused by abnormal overcurrent. In addition, the response speed of the fuse element is fast, at milliseconds level, and the accurate fuse element can effectively prevent the circuit from tripping. Finally, the fuse element is made of high-temperature materials and does not increase the other components in the line current.

Conclusion

The 0674006.DRT4P fuse is suitable for use in transformer protection, motor circuits, distribution circuits and other parts of power systems. It is composed of an aluminum alloy strip or copper-coated ceramic main fuse element and a support filled with colophony, gypsum and other materials, and can quickly cut off the circuit when the set current value is exceeded. In addition, this fuse has many advantages, such as high breaking capability, fast response speed and accurate fuse element.
