Fuses

Fuses, also known as electrical safety devices, are designed to protect electrical circuits from damage by shutting off electric power when the current flow exceeds a certain level, preventing a potential fire hazard or damage to electrical components. The 0662002.HXLL electric fuse is one of the most commonly used type of fuse in industrial applications.

Application Field

The 0662002.HXLL electric fuse is primarily used in large-scale power distribution systems. Applications for the 0662002.HXLL fuse include power plants, substations, distribution systems, control/safety systems, and industrial machinery. This type of fuse is suitable for both AC and DC systems, and can be used as both a primary and a secondary protection device.

Working Principle

The 0662002.HXLL electric fuse is a thermal-magnetic type of fuse. It uses a combination of a metal strip, a heat-sensitive material, and a magnet to achieve its purpose. The metal strip conducts electric current and heats up when the current is too high. The heat-sensitive material melts when it reaches a certain temperature, breaking the electric connection. The magnet is used to help the strip return to its original position, allowing the fuse to operate the same cycle multiple times.

This type of fuse has two main operating characteristics: an overload current-limiting characteristic and a short-circuit current-interrupting characteristic. The overload current-limiting characteristic is the fuse’s primary purpose — to protect the circuit from an overload by limiting the current. The short-circuit current-interrupting characteristic is a secondary purpose — when a short-circuit occurs, the fuse will break the connection and stop the flow of current.

The 0662002.HXLL fuse is also designed to be fail-safe, meaning that if the fuse fails for any reason, it will remain open and no current will flow. This is to ensure that even if the fuse is not replaced, the circuit will remain safe.

Advantages

The 0662002.HXLL fuse has many advantages over other types of fuses, including higher current ratings, lower operating costs, lower installation costs, and a longer life span. The fuse can be used in a wide range of operating temperatures and is designed to be fail-safe, making it a reliable protection device.

Disadvantages

The 0662002.HXLL fuse is not without its drawbacks. It is not suitable for circuits with very high voltage, as the fuse may not be able to withstand the voltage and could fail prematurely. In addition, the fuse may not be suitable for circuits that require very fast response times, as the fuse takes time to operate.
