TVSS Surge suppressor

Correct application for a specific surge suppressor

When a surge causes the voltage to exceed its normal value, the surge arrester holds or ``clamps`` the voltage.  At the same time, the surge arrester dissipates and diverts the transient current until the surge passes.  After the surge, no parts need to be replaced or reset on the surge arrester.
