Overload Curves
Starting: Programmable for Class 5 through 30
Run: Programmable for Class 5 through 30 when "At-Speed"
is detected.

Retentive Thermal Memory
Overload circuit retains thermal condition of the motor
regardless of control power status. Unit uses real time clock
to adjust for off time.
Dynamic Reset Capacity
Overload will not reset until thermal capacity available in the
motor is enough for a successful restart. Starter learns and
retains this information by monitoring previous successful
starts.
