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