Abstract
An overvoltage protection plug is provided, including at least one voltage-limiting component with an associated fuse element and a fail-safe device (6). The fuse element trips the fail-safe device (6) in the event of thermal overheating. The fail-safe device can optionally be upgraded with visual fail-safe signaling, wherein the voltage-limiting component is arranged with the associated fuse element and the fail-safe device (6) as an enclosed unit on a first printed circuit board (3) to which, optionally, the visual fail-safe signaling, which is arranged on a separate, second printed circuit board (10), can be assigned.
