170M4247 Application Field and Working Principle

The 170M4247 is a high current auto fuse, which belongs to the class of auto fuses. 170M4247 has high current rating and time-delay, which make it ideal for a number of applications.

The 170M4247 has a rated current of 40A and a rated voltage of 32V. It is a time-delay auto fuse which is characteristic of 170M4247 that it can delay the current so that the protection devices can respond in time effectively. The melting time of the fuse is 8 seconds at 150 percent of rated current, and the melting time is 30 seconds at 200 percent of rated current.

170M4247 has two uses – it can be used as an isolator and as a current-limiting device. As an isolator, the 170M4247 can effectively block the current overload and short-circuit which may damage the protected equipment. As a current-limiting device, the 170M4247 can effectively limit the current from a high current to a level that can be absorbed by the protected equipment，ensuring that the protected equipment is not destroyed by the large inrush current.

170M4247 is also used as a switch and it can be used to disconnect the power supply fast when necessary. The operating temperature of the 170M4247 is -40 degrees Celsius to 125 degrees Celsius and the storage temperature is -25 degrees Celsius to 85 degrees Celsius,which is suitable for a majority of applications.

Conclusion

The 170M4247 is a high current auto fuse. It has a rated current of 40A and a rated voltage of 32V. The melting time of the fuse is 8 seconds at 150 percent of the rated current and 30 seconds at 200 percent of the rated current. It is an ideal choice for applications that required high current with time-delay.
