Q1: Is this product suitable for solar PV systems?

Yes. This DC MCB is designed for photovoltaic DC circuits, solar combiner boxes, and DC power distribution systems.

Q2: What current ratings are available?

Available current ratings include 63A, 80A, 100A, and 125A.

Q3: Can it be used for DC500V systems?

Yes. The product supports DC250V, DC500V, DC750V, and DC1000V depending on pole configuration and model selection.

Q4: What is the difference between AC MCB and DC MCB?

DC MCBs are designed for direct current circuits and require stronger arc extinguishing capability than AC MCBs. Solar PV systems should use DC-rated breakers.

Q5: Can this breaker be installed on DIN rail?

Yes. It supports standard 35mm DIN rail mounting.
