Study Notes
Fuse Basics
- A fuse is an essential safety device that protects electrical circuits from overcurrent conditions
Fuse Casing Materials
- The materials used for fuse casing are ceramic, glass, or plastic
- These materials provide insulation, mechanical strength, and resistance to environmental factors
Fuse Components
- A fuse consists of two main parts: the fuse element and the fuse casing
- The fuse element is the conductive material that melts or breaks when the current exceeds a certain threshold
- The fuse casing provides mechanical protection and insulation for the fuse element
Fuse Element Characteristics
- The materials used for fuse elements have high melting points, high conductivity, and low temperature coefficient of resistance
- Examples of fuse element materials include zinc, silver, copper, and tin
Fuse Parameters
- The characteristic parameters of a fuse include the ampere rating, voltage rating, and operating temperature range
- These parameters determine the fuse's ability to protect electrical circuits from overcurrent conditions
