This is the voltage value which, in conjunction with the rated operational current, determines the use of the contactor or starter, and on which the corresponding tests and the utilisation category are based.
For 3-phase circuits it is expressed as the voltage between phases.
For 3-phase circuits it is expressed as the voltage between phases.
Apart from exceptional cases such as rotor short-circuiting, the rated operational voltage Ue isless than or equal to the rated insulation voltage Ui.
