MT66

Voltage Protected Breaker

MT66-PV voltage protected recloser is designed for distributed grid-connected PV system specially. It can monitor the real-time voltage, the device will make trip when the voltage is lower or higher a certain value and it will restart when the voltage come back to the a certain value.
