What is the difference between fuse holder and fuse link?
A fuse holder and a fuse link are two different components used in electrical circuits for overcurrent protection, but they have distinct characteristics and functions.
Fuse Holder:
A fuse holder is a device designed to hold and secure a fuse in place within an electrical circuit. It provides a mechanical and electrical connection between the fuse and the circuit.
The fuse holder typically has terminals or connectors where the fuse can be inserted and held securely. Fuse holders are available in various types and configurations, such as blade fuse holders, cartridge fuse holders, or plug fuse holders.
They allow for easy installation and replacement of fuses and provide a means to protect the circuit from overcurrent conditions.
Fuse Link:
A fuse link, also known as a fusible link, is the actual component that is designed to melt or blow when subjected to an overcurrent condition.
It is a short length of wire or strip of metal with a specific current rating. Fuse links are often found in older electrical systems or industrial applications. They are typically soldered or connected directly within the circuit and provide overcurrent protection by acting as a sacrificial element.
When the current exceeds the rated capacity of the fuse link, it will melt or blow, interrupting the circuit and preventing damage to the wiring and equipment. Unlike a fuse holder, a fuse link does not require a separate holder for installation.
In summary, a fuse holder is a device used to secure and hold a fuse, providing mechanical and electrical connections within an electrical circuit.
A fuse link, on the other hand, is the actual fusible element that melts or blows to interrupt the circuit and protect against overcurrent conditions. Fuse holders and fuse links work together to provide overcurrent protection in an electrical system.
The fuse link is the component that physically melts or blows, while the fuse holder holds the fuse in place and provides the means for installation and replacement.
