Three phase self resetting six display overvoltage, undervoltage, overcurrent, phase loss protection, current limiter, adjustable delay
Undervoltage protector is a multifunctional monitoring and protection instrument for three-phase three wire power supply systems or three-phase electrical equipment. Integrating three-phase voltage display, overvoltage protection, undervoltage protection, phase loss protection (phase failure protection), three-phase voltage imbalance protection, and phase sequence protection (phase error protection). It can be used to monitor important parameters (voltage, phase sequence, phase loss, phase balance) in three-phase power supply systems. In case of abnormal situations that may endanger the safe and reliable operation of the power supply system and equipment alarm signals can be issued in a timely manner to enable the control system to take appropriate measures before the machinery and equipment are damaged, thereby maximizing the protection of the machinery and equipment and systems, improving their effectiveness.syi
