摘要： A circuit breaker and a method of developing the current limiting circuit breaker are described. The circuit breaker includes a carrier assembly to supply current to a circuit through a fixed contact in a first operative state. The carrier assembly includes a latch pin to move responsive to a force transferred to the latch pin as a result of a fault condition in the circuit, a cam assembly in contact with the latch pin to move responsive to movement of the latch pin, and a movable contact coupled to the cam assembly, the movable contact breaking the physical contact with the fixed contact to put the circuit breaker in a second operative state. The circuit breaker also includes a mechanism to move the carrier assembly responsive to a signal indicative of the fault condition to put the circuit breaker in a third operative state.

摘要： A circuit breaker and a method of forming a current limiting circuit breaker are described. The circuit breaker includes a carrier assembly to supply current to a circuit through a fixed contact in a first operative state, a movable contact in physical contact with the fixed contact of the circuit, and a contact arm coupled to the movable contact, the contact arm including a pivot point. The contact arm moves about the pivot point responsive to a force transferred as a result of a fault condition in the circuit and the movable contact breaks the physical contact with the fixed contact of the circuit to put the circuit breaker in a second operative state. The circuit breaker also includes a mechanism to move the carrier assembly to put the circuit breaker in a third operative state responsive to a signal indicative of the fault condition.
