over and under voltage protector

JGGQ-63 Automatic reset over  and under voltage 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.

over and under voltage protector JGGQ-63

JGGQ-63 Automatic reset over and under voltage protector 当供电线路出现过压和欠压时，保护器能在持续的高压冲击下迅速安全地切断电路，避免因异常电压送至终端电器而导致事故的发生，当电压恢复到正常值时，保护器会在规定时间内自动接通电路，确保终端电器在无人值守的情况下正常运行。

2.特点和使用环境

1.发生单相线路欠压时，切断线路，单相线路电压恢复正常，延时后自动复位并接通线路，无需人工操作。

2.当线路中存在瞬态或瞬态过电压时，保护器不会发生故障。

3.当线路电压因假触点等故障而不稳定时，或突然断电而来电时，保护器未与线路连接。

4.当线路故障电压最高时，保护器本身不会损坏。

5.耐冲击电压：4 千伏（符合 III 类电器的安全标准）。

6.环境温度：-25°C~40°C，相对湿度：10%~90%，海拔高度不超过 2500 米，使用场所应有防雨设施。

over and under voltage protector of parameters

1.额定电流：32A、40A、50A、63A

2.工作电压：交流 230 伏，50 赫兹

3.过压保护值：AC270V ±5V

4.欠压保护值：AC170V ±5V

5.故障后重置时间：20 秒

6.行动时间：0.2 秒

7.最高可承受 AC380V 过电压。
