JKSSS+ Series - 2
JKSSS+ Series 2.3 - 4.2KV
1.2 Specifications (continued)
Two Stage Electronic
Overload Curves
Starting: Programmable for Class 5 through 30
Run: Programmable for Class 5 through 30 when "At-Speed" is detected.
Overload Reset
Manual (default) or automatic
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.
