Issue: Are external motor overloads needed when running the motor with ATS46 softstart?
 
Product Line: ATS46
 
Environment: All
 
Cause: N/A
 
Resolution: The ATS46 has integrated motor thermal protection.
The thermal overload class can be adjusted to provide Class 2, 10, 10A, 15, 20, 25 or 30 overload protection as defined per IEC 947-4-2. The thermal overload protection may be turned off if external protection is provided.
External overload protection may be provided if there are multiple motors or if there is full voltage bypass available.
