Abstract (en)
[origin: EP1107269A1] The three phase electrical apparatus has six polar compartments in an isolating material unit. The unit is formed of contact pairs (42) connected electrically by a bridge (70). A second bridge connects adjacent phase poles. Each of the polar compartments has magnetic compensation circuits (82) placed between one of the two bridge connections.
