FIELD: mechanics.
SUBSTANCE: present group of inventions relates to automatic air circuit-breaker. The breaker contains a cam connected with rotating shaft; actuating arm with the possibility of rotation connected with the cam; breech closing spring connected with actuating arm performed with the possibility of compression at actuating arm rotation; many links performed with the possibility of transmitting the extension force appearing at breech closing spring tension towards switching arm connected with moving contact member. Note that at least one of many links has the structure in which many elements are connected between themselves.
EFFECT: improvement of service reliability of automatic air circuit-breaker and increase of its service life at the expense of abrasive wear prevention or links damaging during automatic air circuit-breaker operation.
