The invention relates to a device for stunning an animal for slaughter, for instance a pig which device comprises: transporting means (1) for transporting an animal for slaughter through the device; at least two head electrodes (3,4) for placing against the head of the animal; at least one body electrode (5,35) for placing against the head of the animal, first electrical means connected to the head electrodes for carrying through the brain of the animal a first current pulse; and second electrical means connected to the body electrode for carrying through the body of the animal a second current pulse. The device is characterized in that said first current pulse comprises an alternating current component with a first basic frequency f1 of at least 100 Hz; said second current pulse comprises an alternating current component with a second basic frequency f2 which is lower than f1 and which begins a maximum of 8 s after the start of the first current pulse, and during the contact between the electrodes and the animal for slaughter the relative velocity between the electrodes and the animal for slaughter is substantially zero.
