Setting options
You can influence the 3 tripping functions via different settings.
1.
Inverse-time delayed overload release (electronic)
–
Select the tripping current as the setting current in accordance with the load to be
protected. The compact starter offers a wide setting range in the ratio 1:4 for this
function. In accordance with IEC 60947-6-2, the response value is between 1.05 times
and 1.2 times the value of the current setting.
–
For selecting trip CLASS 10E or CLASS 20E.
2.
Short-time delayed overcurrent release (electronic)
–
Like the inverse-time delayed overcurrent release, the short-time delayed overcurrrent
release is also dependent on the selected setting current. The reponse value is 12
times the setting value and is also variable in the ratio 1:4 in accordance with the wide
setting range.
3.
Instantaneous short-circuit release
–
The instantaneous short-circuit release is set to a fixed value in the individual device
versions. This value corresponds to 14 times the value of the rated operationalcurrent
I
e
of the device.
–
Exception: The device versions with the rated operational currents 0.4 A and 1.25 A
have the same response value as the device version with 4 A.
