Auxiliary switch arrangement for a withdrawable circuit breaker insert

摘要

The invention is based on the object of creating a mounting device for auxiliary switches of a withdrawable circuit breaker insert, which device makes it possible for the auxiliary switch to interact with a contact link support which is arranged movably in the withdrawable insert support, by means of which the main electrical connections are produced between the withdrawable insert device and the busbars. This object is achieved according to the invention in that the auxiliary switches (3) are accommodated in a housing (1) which is mounted on the withdrawable insert support, and in that the auxiliary switches (3) are controlled via a slide (2) which is hinged on the contact link support. The invention is used in the case of withdrawable circuit breaker inserts having auxiliary switches which are arranged in a fixed position in the withdrawable insert support and are controlled as a function of the OFF-TEST-ON operating positions of the switch. <IMAGE>
