Frequently Asked Questions (FAQ)

Q1: What does “6kA” mean on an MCB?

A1: It’s the short-circuit breaking capacity—the maximum fault current (6,000 amps) the MCB can safely interrupt without damage. Suitable for most residential and light commercial applications.

Q2: Which trip curve should I choose for home use?

A2:

B curve: Best for lighting and general sockets

C curve: Recommended for air conditioners, washing machines, or small motors

D curve: Only needed for high inrush devices like water pumps or elevators

Q3: Can this MCB be used in outdoor panels?

A3: Yes—as long as the enclosure provides IP protection. The 6kA AC Miniature Circuit Breaker itself operates reliably from –40°C to +50°C, making it suitable for garages, sheds, or meter boxes in harsh climates.

Q4: Are the terminals compatible with standard cables?

A4: Yes—it accepts solid or stranded copper cables up to 25mm², and the notched clamp design ensures a secure, low-resistance connection.

Q5: Why choose CDADA over other 6kA MCB brands?

A5: CDADA offers:

● True CE & CB certification (not just self-declared)

● Wider operating temperature range than many competitors

● Enhanced terminal design for lower heat and longer life

● Clear B/C/D labeling for easy selection

● OEM-friendly pricing with consistent quality from a certified Chinese manufacturer
