5.2.1 Rated voltages
5.2.1.1 Rated operational voltage
The rated operational voltage (hereafter referred to as “rated voltage ” ) of an RCD is the value of voltage, assigned by the manufacturer, to which its performance is referred.
5.2.1.2 Rated insulation voltage
The rated insulation voltage of an RCD is the value of voltage, assigned by the manufacturer. to which dielectric test voltages and creepage distances are referred.
Unless otherwise stated, the rated insulation voltage is the value of the maximum rated  operational voltage of the RCD. In no case shall the maximum rated operational voltage exceed the rated insulation voltage.
