Abstract (en)
[origin: CA2333483A1] A first and a second line (L1, L2) conduct the input direct voltage (Ue) to the load. A fuse (S) is connected in series in the first line. The switching contact (K11) of a first relay (K1) is also connected in series in the first line and is opened during a disconnecting operation. The switching contact (K21) of a second relay (K2) is connected in parallel between the first and second line after the first relay and is closed during a disconnecting operation, after the first relay has been opened. The inventive device is ve ry fault-tolerant, even with usual commercial relays.
