What Should We Do After The PTC Electric Fuse Is Blown?
After the ptc electric thermal fuse is blown, its performance parameter rated voltage is the high voltage that it can withstand after the blow is blown. When the fuse is connected, the voltage on both ends of the fuse is much less than its rated voltage. There are many types of fuse. Common fuses are mainly divided into glass tube fuses (low resolution), and ceramic tubes made of PPTC plastic polymer. There are three types of fuses (high resolution capability) and polymer self-recoverable fuses. In general, when selecting a fuse for the rated voltage of a high-temperature fan, its temperature adjustment depends on its own material characteristics, so the product is much larger than other products. The required circuit voltage is greater than. The rated current is a fuse that can be used for a long time and high current.
When the protection current is Ir, the rated current of the fuse should be selected as the fusing rate of different specifications. As the ambient temperature rises, the operating temperature of the fuse rises and its life shortens. It should be emphasized that the air temperature around the fuse should not be confused with the temperature and temperature of the room. PTC ceramic heating furnace has low cost and long life. There is no need for special thermostats, thermal resistance thermocouples and other temperature sensors used to control the heating of the heater.
