ABSTRACT:
A circuit breaker apparatus is provided with remote controlled opening and closing of its circuits and with supports for the mobile and fixed contacts which are adapted so as to promote repulsion forces which produce a limitation of the short circuit currents, in combination with a small mass of the mobile parts, the one supporting a retractable fixed contact being associated by an extension with a slide which is moved by the remote control electromagnet.
