5MT 100 Application Field and Working Principle

As an electrical and mechanical device, 5MT 100 is used to protect circuits from excessive current and overvoltage. As a fuse, 5MT 100 is categorized in four different types according to its application field and working principle.

Slow-Blow Fuses/Time-Delay Fuses

Slow-Blow Fuses, also known as Time-Delay Fuses, are rated to withstand short-term current overloads that can occur in a brief period of time. They are commonly used in motor starting circuits and when circuits are exposed to in-rush current due to the charging of capacitators. This type of fuses will open when the current exceeds the rating, however, they are designed to respond slower than standard fuses. This feature allows them to protect the circuit from in-rush current without interruption.

Fast-Acting Fuses

Fast-Acting Fuses are engineered to respond quickly when encountering with short circuits, overcurrent, or other overloads. They are commonly used for power supplies, control and instrumentation, lighting circuits, and motors where a fast response is required to prevent equipment and cabling damage. The operating time of Fast-Acting Fuses are less than 1/20th of a second and usually, the current response of Fast-Acting Fuses are below 6A.

High-Voltage Fuses

High-Voltage Fuses or HRC Fuses are designed to provide overcurrent protection for applications which operate at high voltages. They have been designed specifically for high voltage AC or DC power circuits, motors, transformers, cable circuits and other electrical installations where high combusting resistance is required and high-voltage circuit protection is necessary. 5MT 100 High-Voltage Fuse has melting point at 810°C and is able to deliver good melting performance in over-voltage conditions.

High-Speed Fuses

High-Speed Fuses are designed to offer superior current-limiting performance at amperages from 10A to 200A. It is suitable for applications that experience prolonged overcurrent such as motors or transformers. It also offers superior overload protection for high-power semiconductor circuits. This type of fuses can continue to operate itself at a temperature range between -40°C to 125°C. Compared to other types of fuses, High-Speed Fuses can provide better physical protection and are even able to withstand high humidity and vibration.

How Does 5MT 100 Fuse Work?

Fuses are designed to open circuits and protect them from damages due to overcurrent. The 5MT 100 Fuse is constructed with a metal strip connected in series with the line. When the current through the fuse exceeds its rated amperage, the metal strip will heat up and eventually melt, disconnecting the line and thus, protecting it from excessive current.

The 5MT 100 Fuses comes with a variety of features, such as extended temperature range, high current carrying capacity, and it is UL approved, making it suitable for industrial and consumer applications alike.

Conclusion

In short, the 5MT 100 Fuse is a great choice for general-purpose circuit protection due its varied application fields and working principles. It can be found in a wide range of industrial and consumer applications.
