Abrégé

A protection apparatus for protecting a surge protection device has a current-diverting circuit connectable between a surge protection device and a power distribution circuit, the current-diverting circuit comprising a main switch, a current sensor configured to generate a detection signal in response to detecting a current in the current-diverting circuit, and a controller configured to test a tripping condition and to open the main switch in response thereto, wherein the tripping condition is configured to avoid opening the main switch in response to the surge current. The current-diverting circuit further has a fuse element connected in series with the main switch, wherein the fuse element is rated to withstand the surge current and to melt into an open state in response to a high intensity current, in an urgent disconnection delay shorter than a time required by the controller to test the tripping condition.
