TRIP LATCH ASSEMBLIES FOR CIRCUIT BREAKERS AND RELATED CIRCUIT BREAKERS |
摘要 |
Circuit breakers that include and/or a trip latch assembly that is configured to maintain open and closed energy status of the breaker. The trip latch assembly can include: a first stop cam held on a cam shaft; a second stop cam held on the cam shaft axially spaced apart from the first stop cam; a drive cam held on the cam shaft; a trip-open latch held on a trip latch shaft, (typically above) in cooperating alignment with the first stop cam; a trip-close latch held on the trip latch shaft above and in cooperating alignment with the second stop cam; a follower residing below and in communication with the drive cam; and a linkage attached to the follower and to a main shaft to open and close the breaker responsive to the position of the drive cam. |

1. A trip latch assembly for a circuit breaker, comprising:
a cam shaft; a drive cam attached to the cam shaft adapted to communicate with a follower that directs an actuator to move between open and close positions of a circuit breaker; at least one stop cam on the cam shaft, and at least one latch member in cooperating alignment with a respective at least one stop cam, wherein the latch member cooperates with the stop cam to maintain the actuator in the open position and/or close position to thereby maintain open and closed energy status of the circuit breaker. |
