trip. If an overload trip occurs and automatic reset mode is selected, the E300
Electronic Overload Relay will automatically reset when the value stored in %
Thermal Capacity Utilized (Parameter 1) falls below the value stored in

E300 Overload Relay can be manually reset after the % Thermal Capacity
Utilized is less than the OL Reset Level.
