Off-phase sequence protection relay
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.

Features

Due to the uptight electricity supply, inadequate power supply and unstable voltage of part area in domestic and foreign countries, great inconvenience is caused to the use of electric power in the family then directly affected the safely of using electricity at home. to tackle this situation, we organized a strong research and development team and successfully developed the latest generation of automatic over/under voltage protection! It solves the problem of electricity safety in the family directly and effectively, and protects the power control reasonably of power lines to the secondary circuit and prevents form the damage of electrical appliances resulting from various factors!

The automatic over/under voltage protector complies with modular design standards. the circuit boards of products adopt imported electronic components with reliable performance. when the power situation is unstable. its protection function will be automatically activated. once the voltage exceeds the limited range of products, it will automatically cut off so as to protect the safely of electrical equipment and persons. When the voltage returns to normal indic ators on the panel show very intuitive work states, first indicator (red) is shinning to show that product is in the state of over voltage, power can break au tomatically, and the second indicator (green) is shinning when power is normal supply, the third indicator (red ) is shinning when under voltage state, when the fourth indicator (yellow) is shinning, power of product re-supply for 2-3 minutes.
