Can you put a breaker alone without fuses on the line side of the Altivar ATV16 unit or do you need both in series?

Issue:
Wondering if you can you put a breaker alone without fuses on the line side of the Altivar ATV16 unit or do you need both in series?

Product Line:
ATV16

Environment:
All

Cause:
N/A

Resolution:
We do not recommend that a circuit breaker be used without the fuses. The units have been tested and coordinated, with the fuses, we recommend. The circuit breaker alone may not adequately protect the unit.
