Tripping current (average)
The current-time curves for 3-pole symmetrical load show the
relationship between the release time from cold and multiples of
the operational current.
If the device is pre-loaded with 100 % of the current setting, the
tripping times are reduced.

Tripping current (average)
In the case of 2-pole loading (failure of one phase) or current
unbalance > 40 % of the current setting, the tripping times are
reduced, because the heat generated due to the unbalanced
loading of the motor rises.
