Does the 9065 ST520, feature base unit, have ground fault detection?
Issue:
Do the solid state overload relays provide ground fault protection?

Product Line:
NEMA and Definite Purpose Contactors and Starters

Environment:
9065 SSOLR

Resolution:
Yes, the feature base units come with Class 2 ( equipment ) ground fault detection. The phase imbalance circuit will trip the overload within 3 seconds if the unbalance exceeds 25% of the Motor Full Load Current. The Ground Fault circuit will inhibit the trip if the Ground Fault value exceeds 9 to 12 times the maximum dial setting to allow the appropriate ground fault protection device to protect the system.
