Abstract
An overvoltage protection element, with a housing, at least one overvoltage-limiting component in the housing, two connecting elements for electrical connection of the overvoltage protection element to the path to be protected, and an electrically conducting disconnection element in electrically conductive contact with the first connecting element at one end and with a solder connection to the overvoltage-limiting component at another end, the solder connection separating when a temperature threshold of the overvoltage-limiting component is exceeded so that a resulting disconnection point, formed electrically isolates it. Reliable isolation of a defective overvoltage-limiting component and high puncture strength and resistance to creepage are ensured in by a second disconnection point, formed between the first end of the disconnection element and the first connecting element, which interrupts electrically conductive contact between the first end of the disconnection element and the first connecting element when the first disconnection point has opened.
