Abstract (en)

[origin: EP0920098A2] The overvoltage protection element (1) has a housing (5) enclosing a pair of spaced electrodes (2,3) defining a spark path (4). Each electrode has a termination arm (6,7) and a relatively angled spark horn (8,9). The first part of each spark horn extends at right angles to the termination arm, with its outer end curved for providing a curved or angled spark path.
