  • Patent number: 9472359
    Abstract: 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.

  • Patent number: 9443668
    Abstract: A torque regulator assembly is for a stored energy assembly of an electrical switching apparatus. The torque regulator assembly includes: a drive assembly including a gear and a transfer assembly disposed on the gear, the gear being structured to be cooperable with at least one charging mechanism of the stored energy assembly; and a shaft extending through the gear. The drive assembly is structured to move between a driving position and a non-driving position. In the driving position, the gear is cooperable with the transfer assembly to drive the shaft. In the non-driving position, the gear rotates independently with respect to the transfer assembly.

  • Patent number: 9373456
    Abstract: Spring operated actuator devices for an electrical circuit breaker and/or electrical switching device include at least one clock spring comprising a disc shaped body with gear teeth and a spiral spring, a cam shaft holding the at least one clock spring with an inner end portion of the spiral spring attached to the cam shaft, and a drive cam held by the cam shaft adapted to be in communication with a follower that directs an actuator to open or close a mobile contact to maintain open and closed energy status of the electrical circuit. The at least one clock spring is configured as a closing spring of the spring operated actuator.
