A disk-shaped insulator contains a conductive block and an insulating body, wherein the conductive block is located in a central region of the disk-shaped insulator. The radial dimensions of the insulating body are adapted to those of a flange used for connecting. Multiple holes are distributed over an edge region of the disk-shaped insulator, and the edge region is covered by a conductive coating.

An arc chamber for a circuit breaker has first and second mounting bodies. The mounting bodies are disposed at the ends of an electrically insulating insulation section of the arc chamber. The insulation section is formed of at least two shell-shaped partial sections. The partial sections are curved concavely relative to a longitudinal axis of the arc chamber. A gap is formed between the edges of the bodies of the partial sections.
