A suppression circuit, in particular for suppressing the noise of the wiper motor of a motor-vehicle, is provided with at least two capacitors ( ), which are situated between one common ( ) terminal and two separate terminals ( ), and it is provided with pulse limitation. For purposes of pulse limitation, each capacitor has connected to it in parallel the series circuit composed of the cathode-anode path of a diode ( ) and of the anode-cathode path of a Zener diode ( ). The suppression circuit according to the present invention, in one advantageous application, can be embedded as a suppression module in a suppression device, which is provided in a capacitor enclosure. The capacitor enclosure has three contact terminals, which stand in a fixed spatial relationship to each other, irrespective of the number of suppression components, and it can be block-like or cuboid in shape.
