Abstract
A switching chamber insulation arrangement and a circuit breaker having such a switching chamber insulation arrangement are provided. The switching chamber insulation arrangement provides improved heat dissipation in the area of the contact areas of switch contact poles. The switching chamber insulation arrangement includes a strut arrangement having a plurality of struts. Each strut has a first foot area, a second foot, area and a center area which is located between the first foot area and the second foot area, respectively. The struts are arranged along a circumference around a longitudinal extent axis of the strut arrangement. The strut arrangement has a first mechanical coupling area on a side of the first foot areas for coupling to a first pole of a circuit breaker, and a second mechanical coupling area on a side of the second foot areas for coupling to a second pole of a circuit breaker.
