Function
The protection OP trips when the active supplied rises above the set threshold.
If the active power rises above the activation threshold, the protection trips within a fixed time
set by the user.

Description
Activates/deactivates the protection.
Defines the active power value above which the protection is
activated (in reference to the curve, it is the part parallel to the
ordinate).
It is represented both as an absolute value (kW) and a relative
value (Sn, referring to the rated voltage set on the release).
The delay time between the exceeding of the P26 threshold and
the sending of the opening command (in reference to the curve, it
is the part parallel to the abscissa).
Description
Activates/deactivates the protection.
Defines the active power value below which the protection is
activated (in reference to the curve, it is the part parallel to the
ordinate).
It is represented both as an absolute value (kW) and a relative
value (Sn, nominal value defined on the release).
The delay time between the exceeding of the P23 threshold and
the sending of the opening command (in reference to the curve, it
is the part parallel to the abscissa).
