摘要：@ A circuit interrupter comprises a pair of separable contacts 16, 18 and anoperating mechanism for opening and closing the contacts. The operating mechanismincludes a latch lever 44 pivotally mounted on the movable arm 36, and a toggle linkmechanism 58 connected at one end to an operating handle 32 and the other end of

which Is directly engageable with the movable contact arm and the latch lever. Themovable contact arm has a latch surface 72, and the latch lever has a latching end 80, 82which, in cooperation with the latch surface, releasably catches the other end of thetoggle link mechanism. A roller may be mounted on the other end of the second togglelink for quick and smooth operation of the operating mechanism. When tripped, the latchmember 44 is moved away from the latch surface 72 to release the second toggle linkand thereby allow the contact arm 36 to move to its open position.
