Air circuit breaker and link thereof

摘要

An air circuit breaker comprising: a cam (22) connected to a rotational shaft (21) to be rotated; a driving lever (24) connected to the cam to be rotated; a closing spring (25) connected to the driving lever to be compressed by the rotation of the driving lever; and a plurality of links (29,34,35) for transferring a tensile force generated when the closing spring is tensioned to a switching shaft connected to a movable contact, wherein at least one (29) of the plurality of links has a structure that a plurality of members are coupled to one another, whereby operation reliability of the air circuit breaker can be enhanced and a lifetime thereof can be elongated by preventing abrasion or damage from being occurred on the links during the operation of the air circuit breaker.
