Product Q&A

Q:Is this MCB specifically designed for DC systems? Can it be used in standard AC circuits?

Yes, it is specially designed for DC systems (rated 500V/1000V) such as solar PV. Please do not use this DC-rated MCB in standard AC circuits, as the arc extinguishing mechanism is different.

Q:What voltage and current specifications do you offer for this series?

This NB1-63DC series is available in DC 500V and 1000V options. We offer flexible configurations from 1P to 4P, with current ratings ranging from 6A to 63A to suit any photovoltaic system.
