OPERATING MECHANISM OF A MINIATURE ELECTRICAL CIRCUIT BREAKER |
摘要 |
An operating mechanism of an electrical circuit breaker comprises a handle coupled to a transmission rod to form a toggle, a movable contact support device having a plate mounted with rotation on a pivot, and a mechanical link breakable by the action of a trip lever. The link is formed by a retaining catch of the trip lever cooperating with a latch pivotally mounted on a spindle of the plate. The rod is coupled directly to the latch, the assembly constituting a gearing-down stage enabling the tripping force to be reduced. The bimetal strip is connected to the trip lever by a rotating tie-rod with uni-directional transmission.
