Abstract (en)
[origin: EP2455961A1] An electrical switching device suitable for connecting/disconnecting an electrical distribution source and an electrical load connected to an electrical circuit with a line voltage, comprising: - a first pole (2) and a second pole (3), each having a pair of contacts (4,5,8,9) which are mutually coupled to/decoupled from each other; - a differential protection device (50) comprising actuation means adapted to cause decoupling between first pole and second pole contacts. The differential protection device is configured in such a manner as to apply a supply voltage depending on the line voltage to the actuation means after the detection of a differential current higher than the predetermined threshold. The differential protection device is configured in such a manner as to interrupt the application of the supply voltage after the contact decoupling, regardless of the fact that the electrical source is connected upstream or downstream with respect to the contacts.
