An electric household appliance comprising low-voltage capacitive power means (10) connected to the electrical power network (3) and designed to generate a low-voltage (S2, V2), characterized in that said low-voltage capacitive power means (10) comprise a capacitive dividing circuit (28) comprising a first (30) and second input terminal (31) connected to a first and second power line (3) at a first (V 1 ) and second (V REF ) predetermined potential respectively; a first output terminal (32) adapted to generate said low-voltage enabling signal (S2); first (37) and second charge-accumulating means (38) connected between said first and second input terminal; and at least one voltage limiter (40) connected parallel to said second charge-accumulating means (38) and designed to switch from a non-conducting to a conducting state when subjected to a voltage above a predetermined breakdown voltage (VZ); said first (37) and second charge-accumulating means (38) being so designed that the voltage (V c2 ) at the terminals of said second charge-accumulating means (38) is below said predetermined breakdown voltage (VZ).
