170M5813 Application Field and Working Principle

170M5813 electrical fuses are a type of low-voltage AC fuses that are commonly used in many electrical applications. The versatile design of this product makes it suitable for use in numerous environments. In this article, we will explain the main applications of the 170M5813, as well as its working principle.

Application Fields

The 170M5813 is a type of Class CC fuse, which is a type of Low Voltage AC fuse with a size of 0.250 x 0.625 inches. This size makes it suitable for various applications, such as overcurrent protection circuits, control equipment protection circuits, and industrial control panels. Moreover, its wide amperage-range of 5.1 A to 40 A makes it suitable for many different applications. For example, they can be used in motors of up to 10 horsepower, and in the protection of inductive loads. Additionally, its UL listing (the UL Standard 4248 Issue 2) makes it suitable for installation in enclosures, making it an ideal choice for applications where space is an issue.

Working Principle

The 170M5813 works on the principle of fusing. This means that when an excessive current passes through the fuse, the current melts the metal wire inside the fuse, resulting in an open circuit. This open circuit prevents the current from flowing, thus protecting the device from damage due to excess current. To reset the fuse, the metal wire needs to be replaced.

The 170M5813 is designed to handle a wide range of overcurrents caused by excessive voltage, short circuit, and inrush current. In order to ensure safe operation, the fuse is designed to trip when an inrush current of up to 1.5 times its rated current (6 to 60 Amps) is present. In addition, the trip time is designed to be 80% of the I²t rating, which is determined by the combination of the current and time constants.

Conclusion

In conclusion, the 170M5813 is a type of electrical fuse that is suitable for use in a wide variety of applications due to its versatile size and amperage-range. Its UL listing makes it an ideal choice for enclosed equipment, and its low voltage AC characteristics make it suitable for use in overcurrent protection circuits, as well as control equipment protection circuits. Furthermore, its fusing mechanism ensures that the fuse trips within the I²t rating of the fuse, and this prevents the device from being damaged due to an excessive current.
