摘要 The switch comprises a differential current converter (7) which is connected over an evaluation- and trigger circuit (6) with an operating current release (3). The operating current release operates main contacts (10) in monitored conductors (L1, L2, L3, N) over a switching lock (5). A line supply of the evaluation- and trigger circuit and/or the operating current release is connected, electrically separable over auxiliary contact devices (8) with at least two of the monitored conductors. The switch comprises a differential current converter (7) which is connected over an evaluation- and trigger circuit (6) with an operating current release (3). The operating current release operates main contacts (10) in monitored conductors (L1, L2, L3, N) over a switching lock (5). A line supply of the evaluation- and trigger circuit and/or the operating current release is connected, electrically separable over auxiliary contact devices (8) with at least two of the monitored conductors, whereby the line supply of the evaluation- and trigger circuit and the operating current release can be interrupted independently of the connections of the main contacts to the line supply or the load, while an operation is still guaranteed at an interruption of one or two conductors.
