1) Corresponds to section from IEC 60 947-4 (VDE 0660 Part 102):
Coordination type "1":
The destruction of the contactor and the overload relay is permissible. The contactor and/or overload relay must be replaced, if necessary.
Coordination type "2":
The overload relay must not be damaged. Contact welding on the contactor is permissible, if it can be easily
separated again from the contactor.
