Abstract

The present invention discloses a surge / spike protection device. This device includes a varister, a thermal cut-off (TCO) element and a ceramic case. The ceramic case is not filled with insulated package material and the TCO element is not packaged with insulated package material. Accordingly, the circuit is protected by fusing the TCO element if the varistor is overheated due to surge / spike.
