Abstract

The invention relates to a power electrical contactor (13) comprising: - a breaking chamber (15), - at least one fixed contact (16.1, 16.2) disposed inside the breaking chamber (15), and - a movable contact (17) capable of moving between: - a closed position in which the movable contact (17) is in contact with the fixed contact (16.1, 16.2), - an open position in which the movable contact (17) is away from the fixed contact (16.1, 16.2), - an optical detector (20) disposed inside or near the breaking chamber (15), - an electrical breaking element (21), and - a control device (25) configured to activate the electrical breaking element (21) when the duration of an electric arc detected by the optical detector (20) exceeds the nominal opening response time of the power electrical contactor (13).
