•
Residual voltage that is higher than the setting
•
Residual current that is higher than the setting
•
The phase difference of the residual current and the residual voltage is at a level where the
residual current is within the working range.

The residual current's activation level is 100% and the reset level is 95%. The residual voltage's
activation level is 100% and the reset level is 95%. The reset is instantaneous.
The accuracy of the operation time is equal to the preset time plus a maximum of 30 ms.
The operation area of the directional adjusted to an operation angle of 90º and a semi-cone angle of
60º is graphically shown below.
