Lichtbogenlöscheinrichtung mit einem Aufsatz für Niederspannungs-Schaltgeräte

摘要

The invention relates to an arc extinguisher for low voltage switchgear, switching in air, with a universally applicable variable attachment for adjustment of the arc extinguisher chamber to meet increased demands. Said attachment (8) is in the form of a chimney-like arc extinguisher chamber extension, for increasing the volume of the arc extinguisher chamber and represents a moulded piece (10) with a lower outline (16) which exactly matches the outline of the arc extinguisher chamber cover (6; 7; 9), normally located on the arc extinguisher chamber and with an upper outline (17), identical to the upper outline of the switchgear housing for mounting the arc extinguisher chamber cover (6; 7; 9), whereby any number of attachments (8) may be used in a stacked manner.
