Abstract (en)

[origin: WO2010106411A1] The invention relates to the device for overvoltage protection comprising a terminals for connection to protected circuit, while between the terminals there is arranged a current path in which a protective element is connected, while in the current path is created a place (X) for purposeful cutting-off of the current path and to the place (X) of purposeful cutting-off of the current path there is assigned the device for signalling of protection status. In the place (X) of purposeful cutting-off of the current path there is formed an additional fusible thermal stop with pre-set parameters of melting-down, while the elements of current path being purposefully disconnected are connected by means of first solder (21) and the additional fusible thermal stop is formed by a second solder (22), while the second solder has the same or approximately the same temperature of melting as the first solder (21) and the second solder (22) has a lower value of thermal conductivity than the first solder (21).
