An electrical system having at least one load that is protected by a protective device, where a tripping parameter, i.e., a tripping current of the protective device can be set. A control unit is provided to which a measured current value of the current consumed by the at least one load is supplied, where the control unit generates a limit value, which is provided to the protective device for setting a tripping parameter as a function of the characteristic curve of the measured current value. The control unit thus permits ongoing adjustment of the tripping parameters, i.e., the release current, according to the actual operating conditions.
