Project Description
FMB7 DC Mini Circuit Breaker
Introduction
The DC combiner box is used for connecting the photovoltaic array and the inverter, providing lightning and over-current protection, and monitoring the single string current, voltage, temperature of the photovoltaic array, and the state of the lightning protection device. The photovoltaic DC combiner box added the function of the circuit breaker trip when over- temperature or high pv string current, which can effectively prevent the damage caused by the external short circuit.
