Abstract
A circuit breaker including a first and a second contact movable relative each other between an open position, in which the contacts are at a distance from each other, and a closed position, in which the contacts are in electrical contact with each other. The first contact includes one or more contact elements adapted to be in electrical contact with the second contact when the contacts are in the closed position, and a mesh made of metal arranged in thermal contact with the contact elements. The mesh is arranged to at least partly surround the contact elements to allow heat to conduct from the contact elements to the mesh.

A circuit breaker including a first contact and a second contact movable relative to each other between an open position, in which the first contact and the second contact are at a distance from each other, and a closed position, in which the first contact and the second contact are in electrical contact with each other, and the first contact includes:
- one or more contact elements adapted to be in electrical contact with the second contact when the first contact and the second contact are in the closed position, and
- a mesh made of metal arranged in thermal contact with the contact elements, wherein the mesh surrounds and defines a space that receives the contact elements therein to at least partly surround the contact elements.
