Protection Item
Operating conditions and setting range
Action time
Overload (definite time limit)
The running current exceeds the set value
0.5-60s
Setting range: 0.3-16A, 3-160A, 10-999A.
Overload (inverse time limit)
Operating current exceeds the set value
1-5 tripping curve inverse time limit
Setting range: 0.3-16, 3-160A, 10-999A
Underload
The operating current is lower than the set value. Put in after startup.
0.5-60s
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 50%
2s
Current imbalance
The current imbalance rate exceeds the set value. Setting range: 10-50%
5s
* Unbalance rate = phase current - I average current maximum / I average current * 100%
Start delay
During the start-up of the motor, the protector will shield against overload, underload, locked-rotor, and unbalance protection.
Note:
A countdown will occur during the boot process.
0-200s
Locked-rotor
The running current exceeds the set overload factor and is put into operation after the start of the start.
3s
Setting range: 1.5-8 times overload current.
Short circuit
The operating current exceeds 10 times the set overload factor.
≤50MS
Leakage
The zero sequence current exceeds the set value. Setting range: 30ma-2.5A.
1S
A 5A/10mA zero-sequence current transformer must be connected.
Overvoltage
Operating voltage exceeds the set value, the return difference is 5%
5S
Setting range: 65-690V
Undervoltage
Operating voltage is lower than the set value, the difference is 5%
5S
Setting range: 65-600V
