    • A transient voltage surge suppression device includes a varistor assembly having a compact thickness, and two different disconnect elements responsive to distinct overvoltage conditions to disconnect a varistor assembly prior catastrophic failure thereof. The varistor element (134) assembly comprises an insulating base plate (132) mounted stationary in the housing, the insulating plate having opposed first (160) and second sides (162); and a varistor element (134) having opposed first (150) and second sides (152), one of the opposing first and second sides of the varistor being surface mounted to one of the opposing sides of the plate (132) and the varistor element is operable in a high impedance mode and a low impedance mode in response to an applied voltage. Further, the varistor element is a metal oxide varistor and the insulating plate is a ceramic plate (alumina).
