Abstract
An arc quenching device for an air-switching low-voltage switching device includes quenching plates, which are arranged between and attached to parallel insulating walls, as well as a cover. A separate cooling device may be introduced into the space between the quenching plates and the cover. The cooling device is in the form of an insert cartridge and contains deionization technology for switching gases. Attachment pins on the cooling device and corresponding holding openings on the inside of the cover make it possible to fit the cooling device to the cover before this cover engages with the insulating walls.
