What are cartridge fuses? 

Cartridge fuses refer to a specific type of electrical safety device that is low cost and primarily designed for providing overload protection in electrical circuits. These types of fuses are cylindrical shaped and feature a contact point at both ends. Typically, a cartridge fuse is made with glass, ceramic or porcelain. 

Cartridge fuses are marked with different types of speed codes. Hence, choosing the right speed code is essential. The most common markings in cartridge fuses include:

• FF or Flink Flink (Very Fast Acting)
• F or Flink (Fast Acting)
• M or Mitteltrage (Medium Acting)
• T or Trage (Slow Acting) 
• TT or Trage Trage (Very Slow Acting)

How do cartridge fuses work?

Cartridge fuses are constructed with a piece of wire. When an excessive amount of electric current passes through the circuit, the wire melts and breaks the circuit, thus preventing any potential damage. As the fuse blows and the circuit breaks, the device will need a replacement to complete the circuit. 

Uses

Cartridge fuses have a multitude of uses across industrial, domestic and commercial applications. They are comparatively cheaper than other types of electrical safety devices and offer an effective and risk-free way of protecting electrical devices from short circuits. As such, they are commonly used in a ton of applications corresponding to industrial equipment, consumer electronics, domestic appliances, and more.
