Over voltage protection, over-voltage three-phase resettable protection

JGGQ-63 since the double over undervoltage protection control circuit uses a low-power high-speed micro-processor core, magnetic relays main circuit, standard modular design, when the supply line overvoltage, undervoltage, protection quickly and safely cut off the circuit under continuous high pressure shock, avoid abnormal voltage electrical terminal into an accident caused when the voltage returns to normal, the protection circuit will automatically turn on within the specified time to ensure electrical terminal unattended Under normal operating conditions.
