ELECTRICAL SWITCHING APPARATUS, AND CHARGING ASSEMBLY AND INTERLOCK ASSEMBLY THEREFOR

摘要

An interlock assembly (200) is provided for a circuit breaker charging assembly (100). The charging assembly (100) includes a cam shaft (102), a latch mechanism, such as a D-shaft (104), a latch assembly (106), and a charging handle (120). The charging handle (120) pivots the cam shaft (102). The D-shaft (104) is pivotable between first and second positions corresponding to the D-shaft (104) latching and unlatching the latch assembly (106), respectively. The interlock assembly (200) includes a lever (202) coupled to and pivotable with the D-shaft (104), and a latch interlock (204) pivotably coupled to the circuit breaker housing (4). The latch interlock (204) moves between locked and unlocked positions corresponding respectively to the first end (206) of the latch interlock (204) moving the lever (202) to position the D-shaft (104) in the second position and the first position. Unless and until the stored energy mechanism (10) is substantially fully charged, the latch interlock (204) is disposed in the locked position and the latch assembly (106) is.. movable with respect to the D-shaft ( 104).
