Issue:Is an external thermal overload protection needed to be installed with an ATS01?
Product Line:
ATS01, Altistart 01
Environment:
All
Cause:
N/A
Resolution:
The ATS01 softstart does not provide motor overload protection. Separate overload thermal protection should be added to the power circuit. This typically is done with a motor starter upstream of the ATS01.
