Detailed Description

HonNiu Electric Co.,Ltd Products Off Phase Sequence Protection Relay Click to enlarge image Origin China Detailed Description Protect function: Over-pressure protecting, Low voltage protecting, phase-failure protect, phase sequence protect, voltage imbalance protect. Over Voltage Protecting: 380 to 460, 220 to 260, 1 to 5s(adjusting) Low Voltage Protecting: 300 to 380, 180 to 220, 0.5 to 5s(adjusting) Phase-failure protect and phase sequence protect: < 0.1s At three-phase AC motor in has made under-voltage, open-phase protection and irreversible transmission device for phase sequence protection, with reliable performance, wide application and easy to use and so on. The family protector according to Fig access the power control loop, which can play a protective effect, three-phase circuits of any one fuse or open circuit Open-phase power supply line when there is immediate action CW-3 control to cut off the main circuit contactor AC contactor coil power supply, so as to achieve the main contactor AC contactor moves off of the motor phase protection. When irreversible three-phase equipment (such as pumps, fans, air compressors, elevators, electrical, etc.) that the phase sequence at after repair or alteration of power lines and the original phase sequence that mistake next time, CW-3 series with same ability to discern Preface reliable job, and stop on the circuit power supply to achieve the purpose of protective equipment
