5.FAQ

Q: What devices use DC current?

A: Examples of DC electronics include:

Cell phones.

Flat-screen TVs (AC goes into the TV, which is converted to DC)

Flashlights.

Hybrid and electric vehicles.

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

A: Difference between AC MCB and DC MCB:

AC MCB is extinguished with the help of zero crossings but a DC MCB is extinguished with the help of a mechanical interruption or with cooling. DC MCB's open faster as compared to AC MCB's.

Q: How do I choose a MCB for DC?

A: Hence, while choosing a suitable DC MCB, first, you should determine the circuit's total current. Then, you should select the proper MCB. The current rating of MCBs should not be greater than the cable current carrying capacity.

Q: What's your production capacity of DC MCB?

A: We can make 300,000 pole one month. If you have order plan, feel free to contact me, I will tell you delivery time according to your demand.
