In this respect, it is even thought that the actual functioning of this device is questionable. Indeed, the single mobile part of short-circuit in the device of the application WO 99/21255 could enlarge the holes of the terminals, towards a flared global shape, during its projection through these terminals. This would result from a phenomenon that is well known in ballistics.

These movable contacts 61 to 63 are further connected to the fixed contact 60, which is connected to the earth by a driver not shown for the sake of clarity.

  • the short-circuiter 1 is also able to resist for periods of 100 to 500 ms to short circuits whose current has an intensity of between 10 kA and 150 kA rms. It follows that the short-circuiter 1 is particularly suitable for the protection of a high power electrical installation, although it may also be suitable for another installation, such as a medium power installation.
  • the short-circuiters of the prior art fail to short-circuit the phases of a three-phase installation in about 20 ms at best, the short-circuiter 1 has the advantage of being extremely faster, since it can short-circuit the phases of a polyphase installation in less than 1 ms.
