Product Description

Current interruption in vacuum
The vacuum circuit-breaker does not require an interrupting
and insulating medium. In fact, the interrupters do not contain
ionisable material.
In any case, on separation of the contacts an electric arc
is generated made up exclusively of melted and vaporised
contact material.
The electric arc remains supported by the external energy
until the current is cancelled in the vicinity of natural zero. At
that instant, the rapid reduction in the load density carried
and the rapid condensation of the metallic vapour, leads to
extremely rapid recovery of the dielectric characteristics.
The vacuum interrupter therefore recovers the insulating
capacity and the capacity to withstand the transient recovery
voltage, definitively extinguishing the arc.
Since high dielectric strength can be reached in the vacuum
