Abstract: The surge protection element comprises an inert gas-filled protective device with electrodes inserted between two line input terminals, these terminals being connected respectively to branch terminals of an installation to be protected. The surge protection element also comprises initial protection apparatus, intended to be inserted between the terminals of the installation to be protected, and having a response time and a voltage threshold below that of said protective device, and also decoupling apparatus connected in series between the terminals of the protective device and those of the initial protection apparatus. The decoupling apparatus are capable of causing the voltage to rise at the terminals of the protective device when the current strength passing through the initial protection means increases, whereby the protective device can be tripped and can take over from the initial protection apparatus.
