OUPA DGGQ3-63 self-recovery protector

DGGQ3-63 self-recovery over-voltage andunder-voltage protector(hereinafter referred to as the protector) is suitable for load line with ACvoltage single-phase 230V/three-phase 400V,frequency 50/60 Hz, rated operating current 63A and below.

When the circuit  voltage is abnormal due to single-phase (three-phase) over-voltage caused by the neutral ine fault in the circuit, serious unbalanced three-phase load, too large line resistance, phase loss or high-order harmonics, the protector can automatically disconnect the load-side power supply,thereby preventing damage to the electrical equipment and realizing theprotectionoftheelectrical equipment.

Also,theprotector can automatically detect the line voltage, and can automatically close when the line has a normal voltage, thereby restoring the power supply to the electrical equipment. The product shall be used in series with a circuit breaker, mainly used in the incoming branch box or other power distribution lines to be protected in the civil and commercial buildings.
