The voltage restrained characteristic is shown in figure below.
Figure 3-30: Voltage restraint characteristics
Voltage controlled characteristics
In this case the overcurrent protection operates only if the voltage is below the “U_lowlimit”
value and the current is above the
“SatrtCurrent” value. (No ope
ration is expected if the
voltage is above the U_lowlimit” value.)
