Abstract: A method is provided for managing a fault event in a network for distributing low-voltage or high-voltage electrical energy, which comprises at least one voltage source and a load. The method includes performing at least one step of a first procedure for detecting the existence of fault conditions in the load and performing at least one step of a second procedure for determining, on the basis of the evolution in time of the derivative of the instantaneous current in the load, the state of execution of an interruption manoeuvre started by at least one protection device adapted to interrupt locally the passage of current in the load. An electronic protection unit is also provided that is able to execute the aforesaid method.

Abstract: The present invention relates to a switching device, in particular an automatic switch, a disconnector or a contactor, with high dependability, for use preferably in low voltage electrical systems. In particular the invention relates to a single-pole or multi-pole double break switching device for low voltage systems comprising, for each pole, at least a first pair of contacts and at least a second pair of contacts. Each pair comprises a stationary contact and a movable contact which can be reciprocally coupled/decoupled at the level of a first breaking cavity and a second breaking cavity respectively. Said cavities are defined inside a casing which comprises a first surface with respect to which an internally hollow portion protrudes, said internally hollow being integrally made with at least one portion of the casing. The hollow portion defines, for each pole, one or more discharge channels each of which has a first section communicating with the corresponding first breaking cavity and a second section communicating with the environment outside the casing to permit the discharge of gas from the inside of the first breaking cavity.
