Abstract
An exemplary magnet arrangement improves the running characteristics of a switching arc generated upon the interruption of a current circuit in a pre-chamber of a low-voltage circuit-breaker, in which the switching arc is directed between two electric arc running rails. The exemplary arrangement includes an open magnetic circuit having a magnetic material and at least one permanent magnet that delivers magnetic flux to the magnetic circuit, with magnetic induction generated in a vicinity of the pre-chamber acting upon the switching arc. The magnetic material can be configured as a U-section sheet metal plate which extends along the length of the pre-chamber and includes a material recess which extends through this pre-chamber metal sheet and is arranged to contain the at least one permanent magnet. The exemplary arrangement is of a simple construction and permits adjustment of magnetic induction acting in the pre-chamber of the low-voltage circuit-breaker.
