A surge absorber is a protective device which reduces the steepness of wave front of a surge by absorbing surge energy. Although both surge diverter and surge absorber eliminate the surge, the manner in which it is done is different in the two devices. The surge diverter diverts the surge to earth but the surge absorber absorbs the surge energy.
Let us explain surge voltages in greater detail. When an inductive load, such as a relay coil, is cut off from a circuit, the load generates a high voltage of hundreds to thousands of volts in the reverse direction to the source voltage. This voltage
