CIRCUIT BREAKER

摘要

The invention relates to a circuit breaker comprising two contact elements (2a, 2b, 2c, 2d, 2e, 2f), which at their ends pointing at each other are connected to at least one contact member (8a, 8b) each, wherein the contact elements (2a, 2b, 2c, 2d, 2e, 2f) are mobile relative to one another such that the respective contact members (8a, 8b) can be brought in contact with one another, wherein at least one of the contact elements (2a, 2b, 2c, 2d, 2e, 2f) is at least partially made of a carbon fiber material (3a, 3b, 3c, 3d, 3e, 3f), which at a temperature of 20 degrees Celsius has a thermal conductivity of more than 400 W/m-K, at least in one direction.
