摘要
A multipole low-voltage circuit breaker with an insulating material housing and arc quenching chambers. By a new mechanical design, the installation of the arc quenching devices is to be facilitated. All arc quenching chambers of a switchgear are arranged in a quenching chamber housing which is subdivided by partitions and is fastened to the insulating material housing of a circuit breaker. The quenching baffles are fastened directly to the walls of the arc quenching chambers. A low- voltage circuit breaker with an insulating material housing of compact design is thus provided.
