Functions
6.5 Overload protection
The following trip classes can be parameterized according to IEC 60947-4-2:
● CLASS OFF
● CLASS 5 (10 A)
● CLASS 10
To protect the switching elements in the main circuit against impermissible operating states,
an integrated intrinsic device protection is provided in the upper load range. At overload
currents greater than 65 A, shutdown becomes effective earlier than with the motor
protection function (intrinsic device protection model).
The setting range of the overload protection is 1:3.
You can find more information about intrinsic device protection in chapter Device protection
model (Page 95).
