<p>The device (1) has two connection terminals (2, 3) for electrically connecting the device to an electrical installation. A circuit electrically connects the terminals and comprises two branches (4, 6) connected in series, where the branches respectively comprise small dimension spark gaps (5, 7) formed by thyristors. A triggering unit (10) passes the gaps from a blocking state, where the gaps oppose current circulation in the branches, to a passing state, where the gaps permit a fault current to flow in the branches. Independent claims are also included for the following: (1) a method for protecting an electrical installation against surges (2) a method for fabricating an electrical installation protection device.</p> |
