摘要： An accessory device for protection against permanent overvoltages in a low voltage power distribution line. The accessory device is aimed at coupling to a RCCB, which comprises:

a couple of a electrical contacts including a fixed contact and a movable contact, said movable contact being uncoupled from said fixed contact, during an opening operation of said RCCB; and
sensor means, suitable to generate one or more sensing signals, which are indicative of the presence of an imbalance current between the phase and/or neutral conductors of said power distribution line; and
release means, which are electrically coupled to said sensor means, said release means being operatively connected to said movable contact in order to uncouple said movable contact from said fixed contact upon activation by said sensor means.

The accessory device, comprises first electronic means, suitable to generate an electrical intervention signal, when the voltage value of the power distribution line exceeds a first preset threshold value. The electrical intervention signal is suitable to determine an opening operation of the RCCB, so as to provoke the interruption of the power distribution line.
