JGGQ-63 Automatic reset overvoltage and undervoltage protector adopts the control circuit with high-speed micro-low-power processor as the core, magnetic latching relay as the main circuit, and modularized standard design, when the power supply line appears overvoltage and undervoltage, the protector can quickly and safely cut off the circuit under the continuous high-voltage impact to avoid the occurrence of accidents caused by abnormal voltage sent to the terminal electrical appliances, and when the voltage returns to normal values, the protector will automatically turn on the circuit within the specified time to ensure the normal operation of the terminal appliances in the unattended situation.

JGGQ-63 Automatic reset overvoltage and undervoltage protector adopts the control circuit with high-speed micro-low-power processor as the core, magnetic latching relay as the main circuit, and modularized standard design, when the power supply line appears overvoltage and undervoltage, the protector can quickly and safely cut off the circuit under the continuous high-voltage impact to avoid the occurrence of accidents caused by abnormal voltage sent to the terminal electrical appliances, and when the voltage returns to normal values, the protector will automatically turn on the circuit within the specified time to ensure the normal operation of the terminal appliances in the unattended situation.

1. Introdução

JGGQ-63 Automatic reset overvoltage and undervoltage protector Quando a linha de alimentação eléctrica tem sobretensão e subtensão, o protetor pode cortar o circuito de forma rápida e segura sob o impacto contínuo de alta tensão para evitar a ocorrência de acidentes causados por tensão anormal enviada para os aparelhos eléctricos terminais e, quando a tensão regressa aos valores normais, o protetor liga automaticamente o circuito dentro do tempo especificado para garantir o funcionamento normal dos aparelhos eléctricos terminais na situação de ausência de vigilância.

2. Characteristics and use environment

1. When the single-phase line undervoltage occurs, cut off the line, and the single-phase line voltage will return to normal and automatically reset and connect the line after the delay, without manual operation.

2. When there is transient or transient overvoltage in the line, the protector will not malfunction.

3. When the voltage of the line is unstable due to faults such as false contacts, or when the power is suddenly cut off and the call suddenly comes, the protector is not connected to the line.

4. When the line fault voltage is the highest, the protector itself will not be damaged.

5. Withstand impulse voltage: 4kV (in line with the safety standards of Class III electrical appliances).

6. Ambient temperature: -25°C~40°C, relative humidity: 10%~90%, altitude not exceeding 2500 meters, and the place of use should have rainproof facilities.

Third, the main technical parameters

1. Rated current: 32A, 40A, 50A, 63A

2. Working voltage: AC230V, 50Hz

3. Valor de proteção contra sobretensão: AC270V ±5V

4. Valor de proteção contra subtensão: AC170V ±5V

5. Reset time after failure: 20 seconds

6. Action time: 0.2 seconds

7. The highest is possiblewithstandAC380V overvoltage.
