摘要:
The circuit breaker is characterized by separable contacts (27B, 28B) operable between a closed and an open position a contact arm (46) having a latching surface (46D) and a latch (40) arranged to engage the latching surface (46D) when the contacts (27B, 28B0 are blown-open under short-circuit conditions. The arrangement of the latch (40) allows for a positive lock under high magnitude short circuit levels while minimizing the force required by a mechanism to unlock the arm.

断路器的特征在于可分离触点(27B,28B),其可在闭合位置和打开位置之间操作,具有锁定表面(46D)的接触臂(46)和设置成接合锁定表面(46D)的闩锁(40) 触点(27B,28B0)在短路条件下被吹开,闩锁(40)的布置允许在高大小短路电平下进行正锁定,同时最小化机构解锁臂所需的力。 >
