Also known as inverse time overcurrent protection characteristics. That is, the greater the current flowing through the fuse, the shorter the fuse break time.
Inverse time overcurrent protection refers to the protection that the operating time automatically decreases with the increase of short circuit current.
Inverse time overcurrent protection is mainly used in the power industry, mostly used in power plant motor protection, the use of inverse time overcurrent protection on the power line, can be faster to cut the fault of the protected line head.

The amp-second characteristic, also known as the protection characteristic, is mainly used to characterize the relationship between the current flowing through the overload protection device and the operation time of the protection device.
