Description 

 

 

 

Motor Load Curr.

  

90 % of  FLC 

 

 

 
Motor current as a percentage of Motor FLC.   
Range: 0 - 1200% of  Motor FLC. 
 

Equivalent Curr.

  

90 % of  FLC 

 

 

Equivalent Motor current (increased by unbalance according to Unbalance K 
Factor) as a percentage of Motor FLC.   
Range: 0 - 1200% of Motor FLC. 

Unbalance Curr.

 

0% 

 

Unbalance current. The ration between Positive Sequence current to 
Negative Sequence current. If Motor Load is less than 100% then the above 
ration is multiplied by the factor (Motor Load / 100) to prevent nuisance 
tripping 

Thermal Capacity 

30% of Capacity 

Thermal Capacity used. Simulates motor’s winding temperature according to 
the selected Thermal Overload Curve, to Unbalance Bias and to RTD Bias. 

Trip Level = 100% 

Time to Trip-O/L 

No Trip Expected 

 
 
Time to Start 

0 Sec. 

Expected time to trip at the present current value which is above Overload 
Pickup. 
Range: No Trip Expected - 18 Hours. 
 
Expected time to start, displayed in one of the following cases: 

•

  After "Thermal Trip". This is the expected time of the Thermal Capacity to 

decay to 50% of the maximum "Thermal Capacity". 

•

  After "Too Many Starts" Trip. In this case, maximum value of "Time to 

Start" equals "Start Inhibit" Time.         

 Range  After "Thermal Trip":        0 - 166  minutes 
             After "Too Many Starts" :  1 - 60    minutes 

 
"Time to Trip"

 The expected time until motor trips. (i.e. the time to reach 100% of Thermal Capacity if 

the present current value is maintained). This value is calculated and displayed on the LCD. The host 
computer may read this value through the serial link, and try to take some corrective actions. 

 
"Time to Start"

 The expected time until it is possible to re-start after Thermal Trip  (i.e. the time to 

reach 50% of Thermal Capacity) or after Too Many Starts. This value is calculated and displayed on 
the LCD. 
 

Reset of the Thermal Capacity

 

If Emergency Restart switch is closed, then Thermal Capacity is automatically reset when motor is 
stopped, to allow immediate restart of a hot motor.
