$OC{P}_{(MAX)}$ Maximum overcurrent protection rating

3 Terms and definitions
3.11 rated current of overcurrent protection (OCP) device
current rating of fuse or circuit breaker according to EN 60269-6

4.3 Mandatory information
4.3.2 Electrical, including wiring, information
Overcurrent protection devices with a 1hr, 1,35 $I_R$ overload rating, where $I_R$ is the rated value of the overcurrent protection device, are recommended.

Annex C (informative)
Electrical characteristics for PV power plant design
C.2 Temperature corrections
With the provided temperature coefficients $T_C$ electrical parameters $y$ given for a reference temperature $T_{Reference}$ can be calculated to other operating temperatures $T$:
$y=y_{reference}\cdot [1+T_C\cdot (T-T_{reference})]$
