Operating conditions and setting range
Action time
Overload (definite time limit)
The running current exceeds the set value
0.560s
Setting range: 0.316A, 3160A, 10999A.
Overload (inverse time limit)
Operating current exceeds the set value
15 tripping curve inverse time limit
Setting range: 0.316, 3160A, 10999A
Underload
The operating current is lower than the set value. Put in after startup.
0.560s
The setting range is the same as the overload. Note: The underload value must be less than the overload value.
Phase failure
Current imbalance rate exceeds 50percent
2s
Current imbalance
The current imbalance rate exceeds the set value. Setting range: 1050percent
5s
* Unbalance rate = phase current I average current maximum I average current * 100percent
Start delay
During the startup of the motor, the protector will shield against overload, underload, lockedrotor, and unbalance protection. Note: A countdown will occur during the boot process.
0200s
Lockedrotor
The running current exceeds the set overload factor and is put into operation after the start of the start.
3s
Setting range: 1.58 times overload current.
Short circuit
The operating current exceeds 10 times the set overload factor.
less than 50MS
Leakage
The zero sequence current exceeds the set value. Setting range: 30ma2.5A.
1S
A 5A10mA zerosequence current transformer must be connected.
Overvoltage
Operating voltage exceeds the set value, the return difference is 5percent
5S
Setting range: 65690V
Undervoltage
Operating voltage is lower than the set value, the difference is 5percent
5S
Setting range: 65600V
