摘要： 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.

摘要： A trip actuator reset assembly for a circuit breaker includes a cradle assembly, a reset lever, a trip actuator, and a rigid element. The cradle assembly is pivotably coupled to the circuit breaker pole shaft, and includes a number of springs. A pivot pivotably couples the reset lever to the circuit breaker housing. In response to a trip condition, an actuating element of the trip actuator moves a first end of the reset lever. The rigid element is pivotably coupled to the housing proximate a second end of the reset lever. To reset the trip actuator, a guide member guides the cradle assembly into engagement with the rigid element which pivots the reset lever. The first end of the reset lever then resets the trip actuator. After reset, if the cradle assembly continues to move, then the springs accommodate the additional motion.

摘要： A trip actuator assembly is provided for a circuit breaker including a housing having a mounting surface, separable contacts enclosed by the housing, and an operating mechanism structured to open and close the separable contacts. The trip actuator assembly includes a trip actuator cooperable with the operating mechanism, and a planar member having first and second ends, first and second edges, and an aperture. The trip actuator is at least partially disposed within the aperture and is further disposed between the planar member and the mounting surface of the housing. The first edge of the planar member is removably coupled to the mounting surface, thereby removably coupling the trip actuator to the housing. The circuit breaker may include an accessory tray which is insertable on and is removable from the mounting surface. When inserted, the accessory tray abuts the body of the trip actuator enclosure further securing the trip actuator.

摘要： A heat sink is for an integrally fused low-voltage power air circuit breaker including a line terminal and electrical bus work coupled to a current limiter. The line terminal, electrical bus work, and current limiter contribute to the formation of a thermal dam. The heat sink includes a heat exchanger structured to be coupled to the line terminal at or about the current limiter in order to expel heat from the thermal dam. The heat exchanger comprises at least one conductive member having a first end, a second end, and a plurality of bends therebetween. The heat exchanger includes heat reduction features, such as, for example, two conductive members having a number of air gaps therebetween to facilitate heat convection, a dark coating to expel heat, materials having a high thermal conductivity, and surface-enlarging mechanisms such as fins, flanges and apertures.

摘要： A position indicator assembly is provided for a levering assembly of an electrical switching apparatus, such as a circuit breaker. The levering assembly includes a drive shaft and a racking member movably coupled to the circuit breaker housing. The drive shaft cooperates with the racking member to facilitate racking the circuit breaker into and out of a cassette. The position indicator assembly includes a number of indicator gears cooperating with the drive shaft, an indication rack cooperating with the indicator gears, and an indicator cooperating with the indication rack to provide a visual indication indicative of the position of the circuit breaker with respect to the cassette. When the circuit breaker is moved with respect to the cassette, the drive shaft pivots. In response, the indicator gears move, thereby moving the indication rack and the indicator in order to provide the visual indication.
