Isolating Switch
YJB2-125GQ / 3P+N
Product IntroductionWIFI intelligent reclosing protector is suitable for remote control and multi person control in AC 50HZ and rated 220V power lines. It can be set to turn on and off according to Beijing time and is suitable for remote intelligent control of electrical equipment in various environments, such as homes, schools, enterprises, municipal engineering,…
Scope application
YJB2-125GQ series cost control prepaid photovoltaic overvoltage and undervoltage reclosing (also known as external circuit breakers for electric energy meters) is mainly used in AC 50Hz, rated working voltage 230V/400V, and rated current up to 80A lines to detect the power supply voltage in real time, achieve overvoltage or undervoltage automatic disconnection protection, and automatically reclose after the power supply voltage is restored, ensuring the safe operation of negative equipment within the normal voltage range. It also performs remote automatic closing, opening control or automatic signal control closing and opening of the line, and together with intelligent prepaid electricity meters, forms a complete prepaid electricity meter system.
