Initial temperature rise after restart
When the device is switched on, an initial temperature rise of
70 % is used. Depending of the actual current, the calculated
temperature rise then starts to approach the final value.
Alarm function
The thermal overload stage is provided with a separately
settable alarm function. When the alarm limit is reached the
stage activates its start signal.
Figure 2-10 Example of the thermal model behaviour.
