Low voltage switch pole

A switch pole for a low voltage switching device, the switch pole comprising:

• an insulating casing defining an internal space with a contact area and an arc-extinguishing area of said switch pole;
• a fixed contact assembly and a movable contact assembly positioned in said contact area and including, respectively, one or more fixed contacts and one or more movable contacts, which can be mutually coupled or uncoupled;
• and
• an arc chamber positioned in said arc-extinguishing area and comprising a plurality of arc-breaking plates,
• wherein said insulating casing comprises an insulating wall partially separating said contact area from said arc-extinguishing area, said insulating wall arranged in said internal space in an opposite position relative to said fixed contact assembly and extending from an outer wall of said insulating casing towards said fixed contact assembly,
• wherein said insulating wall includes a channel passing through said insulating wall and connecting said contact area to said arc-extinguishing area, and
• wherein said switch pole comprises an additional arc-breaking element anchored to said insulating wall and partially inserted in said channel, said additional arc-breaking element in electrical connection with a terminal arc-breaking plate arranged in a distal position from said fixed contact assembly as compared to other arc-breaking plates of said arc chamber.
