Fuses:

Fuses are electrical safety devices that protect circuits and components from damage caused by excessive current. The 0034.1521.PT fuse is a high-current time-delay fuse that is designed to protect equipment from electrical overloads and help reduce fire risks. In this article, we will discuss the application field and working principle of the 0034.1521.PT fuse.

Applications:

The 0034.1521.PT fuse is designed to protect a wide range of electronic appliances, including air conditioning units, refrigerators, and washing machines. It is also suitable for use in industrial applications, such as electric motors, transformers, welding sets, and filling engines. The fuse can be applied to voltages ranging from 250V to 500V AC. The long time-delay function of the 0034.1521.PT fuse makes it well suited for protecting load circuits from momentary surges or accidental overloads.

Working Principle:

The 0034.1521.PT fuse is a thermal-magnetic device that uses both heat and magnetism to protect equipments from electrical faults. The fuse consists of a metal strip that has been wound into a helix shape. The metal strip is connected to an encasing that holds the fuse elements. The heat element is made from a composite material that is designed to heat up when there is an excessive current running through it. When the temperature inside the fuse reaches a certain level, the heat-sensitive material will expand, breaking the electrical circuit and thus protecting the equipments.
