Abstract (en)
A contact assembly (105) for a load break switch (100) including:a stationary contact unit (110); anda movable contact unit (120) configured to move between a closed position and an open position, whereinan electric current i) flowing along a current path (140) through the stationary contact unit (110) and the movable contact unit (120) and ii) including an electric arc (142) between the stationary contact unit (110) and the movable contact unit (120) is adapted to generate a magnetic field enabling a Lorentz force (144) to act on the electric arc (142), whereiniii) a structure (122) of the movable contact unit (120) is adapted to form the current path (140) or iv) a structure (112) of the stationary contact unit (110) and a structure (122) of the movable contact unit (120) are adapted to form the current path (140), such that in both cases iii), iv) the Lorentz force (144) enlarges a path of the electric arc (142), to facilitate quenching or extinguishing the electric arc (142), andin the closed position, the structure (122,112) is configured to allow the current flowing through the movable contact unit (120) and the stationary contact unit (110) to flow along a current path (140) that is unaffected by the structure (122,112).
