The main switch of the distribution box at home tripped, and the property electrician unplugged the overvoltage and undervoltage protector DZ47GQ. Is it dangerous? Ask a professional electrician to answer.
Hello:
-★ 1. According to the statement that "the protector reset key always pops up, the main brake can't be turned off, and the brake protector will pop up as soon as it is turned on", your idling is a fault protection action. The "GQ" of DZ47GQ is the pinyin prefix of overvoltage and undervoltage.
-★ 2. Any switch with protection device should not have the phenomenon of "two wires removed". This will make the switch lose overvoltage and undervoltage protection, which is irresponsible and also leaves a safety hazard.
-★ 3. Carefully check the cause of tripping (whether the voltage is normal) and troubleshoot. If the switch is bad, you can replace the high-quality switch.
