Abstract
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.
