Abstract
A circuit breaker includes a housing equipped with a first switchgear region, in which a quenching chamber device and a sliding contact device having movable contacts are located, the contacts lying opposite fixed contacts, and equipped with a second switchgear region, in which a current release assembly consisting of a short-circuit release and an overload release are located. In an embodiment, a continuous ventilation channel is formed within opposing housing walls along the fixed contacts, the channel acting as a first convective air-flow through the circuit breaker in order to dissipate the heat.
