5ST 2.5-R

Fuses are common devices used to protect electrical circuits from overloads and short circuits. They are designed to quickly break the circuit when the current exceeds a certain predetermined level, usually by melting a metal element inside the assembly. 5ST 2.5-R Fuses are one of the most popular types of fuses due to their small size, economical price, and easy installation. The 5ST 2.5-R Fuses are used in a wide array of electrical applications, such as automotive, consumer, and commercial applications.

Application Field:

• Automotive - Used in car and other motor vehicles to protect against short-circuit.
• Consumer - Used in household products such as TVs, air-conditioners, toaster, and irons.
• Commercial - Used in large electrical appliances such as motors, transformers, electric appliances.

Working Principle:

The 5ST 2.5-R Fuse is composed of a fusible element, a body, and a pair of terminal caps. The terminal caps are made of electrically conductive material, usually copper or brass, and provide the electrical connection between the fuse and the circuit. The fusible element, which is typically made of a thin metal strip or wire, acts as a switch, and when the current in the circuit exceeds the level that the fusible element is rated to handle, the element will heat up and melt, breaking the circuit and preventing damage to the entire circuit.

The 5ST 2.5-R Fuse is rated for a specific current level, which is usually visible on the fuse\'s body. The fuse must be replaced with one of the same amperage rating if it is to continue to serve its purpose as a circuit protector. When a fuse is in use, it acts as a current limiting device and helps to protect the circuit from over voltages and reduces the risk of electrocution.
