摘要： A movable arm assembly is for an electrical switching apparatus including a stationary contact and an operating mechanism. The arm assembly includes a biasing member and an arm member having a first end, an opposite second end, a pivot point therebetween, and a portion having a longitudinal axis. A movable contact is disposed at or about the first end. The arm member engages a crossbar member at or about the pivot point such that the arm member can pivot from a first position to a second position. The biasing member engages the arm member at a point between the pivot point and the second end and includes a portion that engages and biases against a housings of the crossbar member. The longitudinal axis of the portion of the arm member is oriented generally parallel to the portion of the biasing member when the arm member is at the first position.

摘要： An arc chamber barrier for a circuit breaker is provided. The arc chamber barrier has a body with a first interlock component that is structured to engage a second interlock component disposed in the circuit breaker primary cover. The arc chamber barrier body is further structured to be disposed in an elongated contact chamber at the interface of an arc chamber portion and an operating mechanism portion. In this configuration, the arc chamber barrier first interlock component resists displacement of the arc chamber barrier body when a pair of separable contacts moves between the second, closed position and the first, open position.

摘要： A microprocessor-based circuit breaker includes a chip that defines the current rating or ground fault current for the breaker. Thus, the maximum current rating and/or ground fault current can be set after manufacture using the chip that is electrically connected to the microprocessor. The breaker includes mechanical components that trip to disconnect the load terminal from the line input. The mechanical components include a floating breaker arm, trigger and tripper lever that cooperate to control the tripping of the breaker. A spring between the breaker arm and trigger, together with cam surfaces defined in the breaker switch cooperate to form a floating linkage to control the position of the breaker arm during on/off activation and current fault conditions. The circuit breaker also includes multiple indicia to provide a visual indication of the type of fault condition sensed by the breaker.
