    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 pole shaft assembly for a circuit breaker includes a receiving portion disposed on the exterior side of the housing, a pole shaft pivotably disposed within the receiving portion and including at least one protrusion, a number of cover members overlaying the pole shaft and the receiving portion, at least one first seal disposed between the receiving portion and a corresponding protrusion, and at least one second seal disposed between such protrusion and a corresponding one of the cover members. The seals resist undesired entry of debris between the receiving portion and the pole shaft, and control the discharge of arc gases from the circuit breaker. The first seal is formed by the interaction between the receiving portion and the corresponding protrusion. The second seal is formed by the interaction between the protrusion and the corresponding one of the cover members.
