When overvoltage or undervoltage occurs on photovoltaic distribution lines, they automatically delay opening, automatically close when voltage is normal, and automatically delay opening when voltage is lost or broken. When voltage is normal, they automatically close. The rated insulation voltage of the circuit breaker is 500V, suitable for 50Hz or 60Hz, rated working voltage is 230V\/400V, and rated current is below 125A distribution lines.
