1. Introduction
JGGQ-63Self-resettable over/undervoltage protectorWhen the power supply line has 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 electrical appliances in the unattended situation.
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. Overvoltage protection value: AC270V ±5V
4. Undervoltage protection value: AC170V ±5V
5. Reset time after failure: 20 seconds
6. Action time: 0.2 seconds
7. The highest is possiblewithstandAC380V overvoltage.
