Issue: 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

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.
