Rated operational voltage (Ue)

A rated operational voltage of an equipment is a value of voltage which,

combined with a rated operational current, determines the application of the

equipment and to which the relevant tests and the utilization categories are

referred to.

Rated insulation voltage (Ui

)

The rated insulation voltage of an equipment is the value of voltage to which

dielectric tests voltage and creepage distances are referred. In no case the

maximum value of the rated operational voltage shall exceed that of the rated

insulation voltage.

Rated impulse withstand voltage (Uimp)

The peak value of an impulse voltage of prescribed form and polarity which the

equipment is capable of withstanding without failure under specified conditions

of test and to which the values of the clearances are referred.

Rated frequency

The supply frequency for which an equipment is designed and to which the

other characteristic values correspond.

Currents

Rated uninterrupted current (Iu)

The rated uninterrupted current of an equipment is a value of current, stated by

the manufacturer, which the equipment can carry in uninterrupted duty.

Rated residual operating current (I∆n)

It is the r.m.s. value of a sinusoidal residual operating current assigned to the

CBR by the manufacturer, at which the CBR shall operate under specified

conditions.

Performances under short-circuit conditions

Rated making capacity

The rated making capacity of an equipment is a value of current, stated by the

manufacturer, which the equipment can satisfactorily make under specified

making conditions.

Rated breaking capacity

The rated breaking of an equipment is a value of current, stated by the

manufacturer, which the equipment can satisfactorily break, under specified

breaking conditions.
