Abstract (en)
[origin: WO2016008729A1] Disclosed is an electric switching device (1, 1') comprising at least two conductor elements (6) which can be placed at a distance from one another and contacted using a moving mechanism (9), and a housing (3) which defines a circuit breaker chamber (5), is made of an insulator (2), and at least partly surrounds the conductor elements (6); at least one face of the housing (3) is provided with a resistive coating (15) which is made of a matrix material filled with a filler, has a sheet resistance between 108and 1012 ohm at the operating field strength, and is conductingly connected to the conductor elements (6).
