In the event of internal failure or aging at the end of the capacitor's operational life, an increasing number of self-healing breakdowns may cause rising pressure inside the capacitor element.
To prevent it from bursting, each capacitor element is designed with internal pressure sensitive interrupter(Protective Device). With rising pressure the cover will bulges to disconnect copper taps at weak points from the cover, and the current path is interrupted irreversibly to avoid the relative disaster.
It is widely used for air-conditioners, refrigerators, generators, illuminating lamps, etc.
