CBRB7-AP PV-Grid Connected Mini Circuit Breaker（Smart MCB）

CBRB7-80APGF and CBRB7-125APGF intelligent multi-functional circuit breakers for photovoltaic systems (hereinafter referred to as circuit breakers) are specially designed for grid-connected distributed photovoltaic power systems. They monitor and judge the voltage of photovoltaic power distribution lines. The breakers will automatically trip with time delay in case of overvoltage or undervoltage, and automatically reclose when voltage returns to normal. They also trip with time delay under voltage loss or open circuit conditions, and restore closing automatically once the voltage is stable. With rated insulation voltage of 500V, these products are applicable to 50Hz/60Hz power distribution circuits with rated operational voltage of 230V/400V and rated current up to 125A.
