If the over current is below cold load pickup current and overcurrent pickup current, protection
functions are not operated during a period of Restore minimum Time (RMT), (Refer the Inrush
Current 2 in “Figure 7-5. The Restore Minimum Time Characteristic”). After RMT, the
protection functions are operated. However, if the over current is dropped below overcurrent
pickup current during the RMT, the cold load pickup function is reset after reset time (Refer the
Inrush Current 3 in “Figure 7-5. The Restore Minimum Time Characteristic”).
Figure 7-5. The Restore Minimum Time Characteristic
If high current trip and high current lockout functions are activated and the fault current is higher
than the current setting of High current trip and high current lockout, the high current trip and
high current lockout functions will be operated prior to the cold load pickup function.
