CLP Summary

The user-set Cold Load time and Cold Load Multiplier are protection settings, only the Cold Load Status/Time is an operator setting.
-
Only the protection elements that are selected, Phase, Earth, SEF, and NPS, are affected by the Cold Load Multiplier.
-
Definite Time settings are not affected.

CLP cannot be used if normal load currents are expected to drop below 2.5 A.
NOTE: It is possible for Cold Load and Inrush Restraint to be applying
multipliers at the same time.
In this situation, Inrush will use the Operational Cold Load Multiplier if it is the higher.
