Abstract
Improvements in contact protection devices of pneumatic circuit breakers with tubular exterior shape and symmetrical with respect to the contact plane whose opening is produced by the action of compressed air and closing by the action of a spring, characterized in that one of the contacts at least it comprises an auxiliary contact which slides telescopically in relation to said contact, projecting with respect to this contact in the open position and sinking at the time of closing against a sufficiently powerful spring to brake the action of the closing spring.
