Electronic switching protection apparatus without generating an electric arc

An electronically switched protection device:

• at least one phase current line and one neutral current line,
• at least one current sensor that is able and intended at least to measure the current flowing through said at least one phase current line or the differential current between the at least one phase current line and the neutral current line and to emit an acquisition signal that is representative of an image of the current flowing through said at least one phase current line or an image of the differential current between the at least one phase current line and the neutral current line,
• an electronic protection tripping device that is electrically connected to said current sensor and is able and intended at least to process said acquisition signal and where appropriate to emit a protective tripping control signal that is representative of the occurrence of a fault,
• an actuator that is electrically connected to said electronic protection tripping device,
• a galvanic isolation mechanism comprising at least a first pair of contacts with a first fixed contact and a first mobile contact that are arranged on the phase current line and a second pair of contacts with a second fixed contact and a second mobile contact that are arranged on the neutral current line, said galvanic isolation mechanism being able and intended to be actuated by a control mechanism of lever type designed to open or close the first and second pairs of contacts or by said actuator,
• wherein said electronically switched protection device comprises:
• an electronic switching unit comprising at least one power electronic switching component that is respectively arranged on said at least one phase current line, said electronic switching unit being able and intended to be made to trip by said protective tripping control signal that is representative of the occurrence of the fault so as to open said at least one electronic switching component,
• an electrical power supply that is configured to supply power to the electronic protection tripping device and to the electronic switching unit,
• in that the actuator is configured to actuate the opening of the first and second pairs of contacts consecutively with the opening of said at least one electronic switching component,
• and in that the electronically switched protection device comprises a housing in modular format.
