| 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. |
