A device and method for protection of an electrical apparatus against touch currents, the device configured to be connected between a source of electrical power and a device onboard a motor vehicle, and including a circuit for detecting leakage currents and for estimating touch currents, configured to be connected to the electrical connection lines of the apparatus, a circuit measuring frame current, and a mechanism controlling operation of the apparatus according to the estimated level of the touch currents and the measured level of the frame current. The device and method can in one embodiment be used to protect against leakage currents during recharging of a hybrid or electrically driven motor vehicle.
