170M3982

The 170M3982 is a type of specialty electrical fuse designed for motor protection applications. This fuse has an interrupt capability of up to 269kA rms symmetrical and can be used in the control circuits of various types of motor drives. Due to its unique features, the 170M3982 can provide efficient motor protection, even in extreme environments that require critical accuracy and protection for various types of motors.

Application Field

The 170M3982 is primarily used to protect single-phase, three-phase, or multi-speed motors from over current, overload, or short-circuit conditions. This fuse is also designed to protect motor control circuits from overvoltage and reverse phase conditions. The 170M3982 is used in applications such as drives, starters, converters, controllers, and motor controllers. Some applications include pumps, fans, machine tools, compressors, electric generators, and electric vehicles. Other applications include industrial processes, marine equipment, agricultural equipment, and electrochemical and plating equipment.

Working Principle

The 170M3982 functions by opening up an electric circuit when a maximum current is passed through it. This is done by melting the metal conductor in the fuse when the current passes through it. This cuts off the power, thus preventing any further electric current from flowing through the circuit. When the current exceeds the prescribed level, an internal element within the fuse melts, and a gap is created between the two ends of the fuse, interrupting the electric current flow. The 170M3982 is designed to hold the current within the prescribed tolerance until the electric current is reduced below the threshold value. After the current is reduced below threshold, the fuse is re-energized and the electrical circuit resumes its normal course.

Conclusion

The 170M3982 is a specialty electrical fuse that is designed to protect single-phase, three-phase, and multi-speed motors from over current, overload, or short-circuit conditions. It can be used in applications such as drives, starters, converters, controllers, and motor controllers, and is suitable for extreme environments that require critical accuracy and protection. The 170M3982 functions by melting the metal conductor in the fuse when the current exceeds the prescribed level. This causes a gap to be created in the circuit, which prevents any further electric current from flowing through the circuit. After the current returns to a normal level, the fuse is re-energized and the electrical circuit is restored.
