Abstract: A device of protection against transient electrical overvoltages, including two voltage-limiting passive components, disconnectors sensitive to the state of these components and adapted to individually disconnect each end of life component therefrom, the components are joined in parallel between a first and a second terminal of the device, where the reference voltage of the first component is inferior to the reference voltage of the second component.
