Abstract (en)

[origin: EP2509092A1] An electric switching device (1) for a low voltage electric circuit, comprising: - at least a first pole (2) having a first moving contact (4) which can be coupled to/decoupled from a corresponding first stationary contact (5), and a second pole (3) having a second moving contact (6), which can be coupled to/decoupled from a corresponding second stationary contact (7); - first detection means adapted to detect a differential current between said first and second poles (2, 3), said first detection means being configured to operate independently from the voltage of said electric circuit. The switching device comprises second detection means, which are adapted to detect an overcurrent flowing in at least one of said first and second poles (2, 3), and which comprise at least a current transformer (50) operatively connected to said at least one of said first and second poles (2, 3).
