Item Type Motor Protector
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 x 100%
Start delay During the start-up of the motor, the protector will 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 startup. 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
