TGZGQ1N

TGZGQ1N self-recovery over-voltage and under-voltage protector is suitable for load line with AC voltage single-phase 230V/three-phase 400Vfrequency 50Hzrated operating current 100A and below.
When the circuit voltage is abnormal due to single-phase(three-phase)over-voltage caused by the neutral line fault in the circuitserious unbalanced three-phase loadtoo 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 the protection of the electrical equipment.Also the protector 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 equipmentThe 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.
