1)Corresponds to section from IEC 60 947-4 (VDE 0660 Part 102):
Coordination type "1": Coordination type "2"
The destruction of the contactor and the overload relay is permissible. The overload relay must not be damaged.
The contactor and/or overload relay must be replaced, if necessary. Contact welding on the contactor is permissible, if it can be easily
separated again from the contactor.
2)Test conditions in acc. with IEC 60 947-4-1
3)Resistance-heated industrial furnaces and electric heating appliances, etc. (increased current consumption at startup of heating taken into account).
