The device has an electromechanical switch (20) connecting electrical input terminals (13-15) of a rotating electromechanical permanent magnet machine (10) to a dissipative-type resistive braking torque producing device (22) in a secure manner. A bipolar assembly of a dissipative resistor (122) forms a common flow terminal bipolar electric load for the terminals. Diodes (120) convert currents from the terminals into single current delivered at two terminals of the assembly, where the diodes are not provided with active power switches.
