摘要： A circuit breaker having a set of electrical contacts, a first actuator in fluid communication with the set of electrical contacts, a second actuator in operable communication with the first actuator, and an operating mechanism in operable communication with the set of electrical contacts and the second actuator is disclosed. Pressurized gas created by separation of the set of electrical contacts acts on and drives the first actuator, which acts on and drives the second actuator, which effectuates tripping of the operating mechanism.

摘要： A pressure sensitive trip mechanism for actuating a circuit breaker operating mechanism to trip a circuit breaker includes a trip lever and a trip bar. The trip lever is rotatable about a first pivot. The trip bar is positioned proximate the trip lever. The trip bar is arranged to rotate about a second pivot in response to a predetermined level of pressurized gas created by separation of the pair of electrical contacts, thereby urging the trip lever to unlatch the circuit breaker operating mechanism. The pressure sensitive trip mechanism provides for very fast tripping of the circuit breaker in the event of a short circuit condition or an overcurrent fault condition within any one on the circuit breaker poles. In a multi-pole circuit breaker, the present invention provides for protection against single-phasing.

摘要： A circuit breaker rotary contact assembly employs a rotor assembly to operate the moveable contact arms. Separate pivots are provided to the rotor assembly and the moveable contact arms to ensure that the contacts close prior to complete rotation of the rotor assembly. The additional rotation force provided by the rotor assembly then translates into lateral displacement of the moveable contacts relative to the fixed contacts, resulting in contact wiping function. An alternate embodiment utilizes a common pivot for both the rotor assembly and the moveable contact arms, while providing post closure motion by means of a fixed contact compression spring.
