PARAFOUDRE AND SELF PROTECTED ELECTRICAL ASSEMBLY COMPRISING SUCH A PARAFOUDRE AND A CIRCUIT BREAKER

摘要

The present invention relates to a lightning arrester comprising a modular block provided with a housing receiving at least one cassette lightning arrester (330). According to the invention, said modular block houses a shaft (190) with at least one locking element (191), this shaft being movable so that its displacement is connected to the movement of an opening and closing device (230) of a circuit breaker (200), in order to take a first safety position corresponding to the closed state of the circuit breaker, in which each locking element cooperates with a complementary portion (334) of a lightning arrester, so as to prevent the withdrawal and / or the insertion of that - latter, and a second access position corresponding to the tripped state of the circuit breaker, in which each locking element leaves free the complementary part of the cassette lightning arrester, so as to allow the removal and / or the insertion of that - ci.
