Voltage Protector
Voltage protector is a multifunctional three-phase three-wire power supply system or monitoring and protection instrument for three-phase electrical equipment. It integrates three-phase voltage display, overvoltage protection, undervoltage protection, phase failure protection (phase failure protection), three-phase voltage imbalance protection, and phase sequence protection (phase dislocation protection). It can be used to monitor the important parameters (voltage, phase sequence, phase loss, phase balance) in the three-phase power supply system. It can send alarm signals in time for the abnormal conditions of the three-phase power supply that may endanger the safe and reliable operation of the power supply system and equipment, so that the control system can properly handle before the machine equipment is further damaged.

Product Features
Automatic reset
This series of circuit breaker accessories are specially designed for use in conjunction with DAB7 (63 frame) circuit breakers and are not intended to be used alone.
Flame retardant material
The four accessories are installed on the left side of DAB7-63 miniature circuit breakers, the DAB7-OF, DAB7-FB, DAB7-QY are fixed with screws, the DAB7-FL is fixed to both sides with tape, and at the same time can be installed with the guide rail.
Overvoltage and overcurrent protection
The mechanical connection between the circuit breaker and DAB7-, DAB7- FB, DAB7- FL, DAB7-QY transmission shaft should be flexible and compatible with the rest of the equipment.
Over current Power Off Time: 1-30s/1-400s
After DAB7-QY circuit breaker has been installed, it can only be closed when press the test button. And installer should shut off the circuit breaker and release the test button immediately, thus ensure the installation safely and correctly. Besides, the rated voltage should pass through the undervoltage trip at same time.
