FAQ

Is the C65H-DCC6A suitable for AC circuits?

No. The C65H-DCC6A is engineered specifically for DC current interruption. Using it on AC systems is not recommended due to different arc-extinction requirements.

What does the C-curve indicate?

The C-curve defines the magnetic trip threshold, allowing short-term inrush currents while still providing fast protection against genuine short circuits.

Can this breaker be used in solar DC systems?

Yes, it is commonly applied in small-scale solar or battery DC circuits where current levels remain within its rated capacity.
