Feature: 1. With overcurrent, phase failure, overload underload protection. 2. Rail mounted method for easy installation. 3. Multiple reset methods for various needs. 4. Digital intelligent motor protector, digital display, more convenient to observe motor status. 5. Can better protect the safety of equipment. Specification: 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 * 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 .
