In a device for disconnecting and/or connecting m phases (u, v, and w) of an alternating voltage providing source ( 1 ) from n phases (n 1 , n 2 , n 3 ) of a load ( 3 ), each of the m phases (u, v, w) of the source ( 1 ) independently is connected by a power switch ( 9 ) with each of the n phases in a mxn matrix. First measuring devices ( 4 ) for monitoring the m phases (u, v, w) of the source ( 1 ) as well as 2nd measuring devices ( 5 ) for monitoring the n phases (n 1 , n 2 , n 3 ) of the load ( 3 ) are provided, and a switching unit ( 6 ) is provided, which controls the switching state of the switches ( 9 ) depending on the state of the m phases (u, v, w) of the source ( 1 ) and of the n phases (n 1 , n 2 , n 3 ) of the load ( 3 ). This construction allows a particularly quick connection and/or disconnection for increased stability.
