Product FAQ
How is a PV MCB different from an ordinary MCB?
PV MCB is designed for the DC side of a photovoltaic system and has a higher rated voltage and breaking capacity, while ordinary MCBs have lower ratings.
What are the advantages of using a PV MCB?
Compared with DC fuses, PV MCBs are small in size, low in cost, highly reliable, and have higher voltage and breaking capacity.
How does a PV MCB achieve overload and short-circuit protection?
PV MCB uses a thermal magnetic tripping mechanism to prevent overloads through thermal effects and quickly cut off short-circuit currents through electromagnetic effects to protect line and equipment safety.
What factors should be considered when selecting a PV MCB?
It is necessary to comprehensively consider the system’s voltage level, short-circuit current, number of loops and other parameters, and reserve a certain margin. It is recommended to consult a professional to assist in the selection.
What matters need to be paid attention to when installing a PV MCB?
During installation, a ventilated and dry place should be selected to avoid direct sunlight and rain. When wiring, ensure that the polarity is correct and do a good job of waterproof sealing.
