3RT10 2. contactors for switching motors
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.
2)Test conditions in acc. with IEC 60 947-4-1.
Unwelded 3RT11 contactors, see Chapter 5 (overload and short-circuit protection only with the 3RV10 circuit breaker).
