摘要： Disclosed is a PTC (Positive Temperature Coefficient) current limiting device for limiting a current by use of PTC characteristics, which includes a PTC element having the PTC characteristics; a pair of electrode units arranged on both sides to face each other with the PTC element being interposed therebetween; and a molding part prepared around the PTC element and the electrode units to surround at least an interface region between the PTC element and the electrode units, the molding part being made of elastic insulating material. The molding part is made of an elastic insulating material or any insulating materials selected from vacuum, gas and oil. Thus, this device may effectively restrain an arc generated while limiting overcurrent or short circuit current, and also prevent flashover between electrodes.

摘要： Disclosed is a PTC (Positive Temperature Coefficient) current limiting device, which limits a current using PTC characteristics. The device includes a PTC element having the PTC characteristics; and upper and lower contact electrodes arranged to face each other with the PTC element being interposed therebetween, wherein, assuming that a distance from an end of the upper contact electrode to an end of the PTC element is a1, a distance from an end of the lower contact electrode to the end of the PTC element is a2, a thickness of the PTC element is b, and L=a1+a2+b, the following equations are satisfied: V/L
