Abstract: Circuit breakers with handles have common trip cams with an integrated spring and trip cam base. The integrated spring directly contacts the armature in lieu of having the trip cam base formed to do so thereby allowing the use of alternative trip cam base configurations and materials from conventional relatively expensive materials.

Abstract: A magnetic trip mechanism for a circuit breaker includes an electrically conductive strap having a first wall portion and a second wall portion that define an interior space therebetween. Also included is a flux block disposed at least partially within the interior space, and movable in response to a short circuit condition of the circuit breaker. Further included is a trip lever operatively coupled to the flux block. Yet further included is a trip latch moveable between a latched condition and an unlatched condition with a handle, wherein rotation of the trip lever occurs in response to the short circuit condition and causes movement from the flux block to actuate the trip latch to the unlatched condition.

Abstract: A circuit breaker assembly includes a housing, a trip mechanism, a vent channel, and a chamber. The trip mechanism is positioned within the housing can causes a movable contact to separate from a second contact in response to detection by the circuit breaker assembly of an electrical fault. The vent channel is formed in the housing and positioned to exhaust gas and debris produced as the movable contact separates from the second contact during the electrical fault to an aperture in the housing. The chamber has a chamber housing coupled to the housing adjacent the aperture such that the chamber receives the gas and debris exiting the aperture.

Abstract: The present invention provides for an electrical switching apparatus operating mechanism opening assembly wherein the toggle assembly stop/kicker pin has been separated into a kicker pin and a stop pin. By separating the functions of the stop/kicker pin into separate pins, the kicker pin may now be located at the pivot point of the associated link. Further, the kicker pin and the stop pin are now disposed upon a cradle assembly as opposed to an elongated link. The cradle assembly further supports one of the toggle assembly links. Thus, rotation of the cradle assembly causes the toggle assembly to move. The operating mechanism opening assembly is configured so that, when an associated latch assembly latch plate assembly is released, the cradle assembly rotates so that the toggle assembly is moved away from a closing assembly closing device.

Abstract: An apparatus and method for restricting auxiliary latch movement within a tripped circuit breaker. An auxiliary latch is held in a closed state and is biased into an open state. When the trip bar is activated in response to an overload condition, it releases the auxiliary latch which pivots to the open state. The cradle is released and pivots to disengage the breaker contact. Tabs on the cradle and auxiliary latch cooperatively interlock to limit auxiliary latch movement until the latch is properly reset.

Abstract: A lever arm assembly is provided for a circuit breaker trip actuator reset assembly including a cradle assembly pivotably coupled to the circuit breaker pole shaft, a reset lever pivotably coupled to the circuit breaker housing, and a trip actuator including an actuating element, which moves the reset lever in response to a trip condition. The lever arm assembly includes at least one linking element including a first end pivotably coupled to the cradle assembly, a second end, a pivot, and a deflection assembly having a deflection member. When the cradle assembly moves from a first position toward a second position, it moves the linking element, thereby moving the deflection member into engagement with the reset lever. This pivots the reset lever to reset the trip actuator. After the trip actuator has been reset, the deflection assembly is deflectable to accommodate excess motion of the cradle assembly.

Abstract: A circuit breaker includes a housing and an operating mechanism having a cross bar supported by a first housing surface and moving in an arcuate path between open/tripped and closed positions, a pivotally mounted cradle including a latch, and pivotally mounted primary and secondary latches. The primary latch includes a pivot, an opening and a free end. The cradle latch rests within the opening when the contacts are not tripped open. The secondary latch includes a pivot and a surface. The latches are between a second housing surface and the cross bar in a first position. The cross bar is offset from the latches in a second position. The secondary latch surface and pivot are between the second housing surface and the primary latch pivot. The secondary latch surface engages the primary latch free end when the contacts are not tripped open and maintain the cradle latch within the opening.
