Abstract:
A switchgear device having a single-pole breaking unit which includes one of a pair of stationary contacts connected to a line-side current conductor, a movable contact bridge for closing and opening the stationary contacts, a line-side panel, a load-side panel opposite the line-side panel and two opposing lateral-side panels, which panels surround the stationary contacts and contact bridge, and form arc extinguishing chambers with a stationary contact within each chamber, an opening volume between chambers, and a quenching gas exhaust channel connected to a chamber, and opening through the line-side panel, which is opposite another load-side panel for contact with a trip device.
