Abstract
The invention relates to a resistance switch-in device for switching in only when a circuit breaker closes, said switch-in device including a moving arcing contact in an interrupter chamber. The device is characterized in that the switch-in contacts (2 and 3, 32 and 33) are disposed in the interrupter chamber (1) of the circuit breaker and that since at least one (2,32,33) of said switch-in contacts is a moving contact, it moves on a path parallel to that of the moving arcing contact (5). The invention applies in particular to connecting a load to long-distance high-tension circuits that are unloaded.
