K81BB57 is a special electronic product designed for protection against overvoltage and lightning. The primary purpose of K81BB57 is to limit transient overvoltage, generated by lighting strikes or other causes, by liberating the power of certain conventional overvoltage protection components. It has a unique structure and utilizes the combined effects of silicon and ferrite whose characteristics are complementary.

The application field of K81BB57 includes but is not limited to domestic electric equipment, machinery, communication devices, computer equipment, automobiles, and heavy machinery. Its features make it highly suitable for the protection of digital control computer boards, communication lines, digital and analog circuits, loop circuits, and electric machines.

K81BB57 works by first sensing the lightning or short circuit current and then automatically limiting its amplitude. This is followed by a rapid variation of intensity, accompanied by a sharp rising edge. The product has a time limiting element which acts in response to the rapid elevation of the voltage overshoot. The time delay of K81BB57 is adjustable in order to meet the exact response time of the specific overvoltage protection components.

K81BB57 is composed of several parts including a time-limiting element, varistor, high-voltage capacitance, safety resistor, and protective circuit. Its working principle is based on the combination of the silicon element and the effect of the ferrite which together form a series of chain reactions. When the lightning, or other overvoltage has been detected, this series of chain reactions come into effect and the device automatically starts limiting its amplitude. At the same time, the time-limiting element ensures that the overvoltage is not allowed to continue for too long.

The K81BB57 product can be used in a variety of industries as an effective form of protection against overvoltage and lightning due to its unique structure and working principle. In addition, the adjustable time delay feature makes it even more suitable for use in digital control computer boards, communication lines, digital and analog circuits, loop circuits, and electric machines. All in all, K81BB57 is an efficient and reliable piece of protection equipment.
