FAQ

Q: What is the difference between the C-curve and D-curve versions? A: The C-curve version trips at moderate inrush currents and is commonly used for standard DC loads. The D-curve variant tolerates much higher inrush currents, making it suitable for DC motors, transformers, or equipment with heavy startup surges.

Q: Is this breaker suitable for AC circuits? A: This model is designed and rated specifically for DC applications. For AC systems, Schneider Electric provides dedicated AC-rated MCBs with different internal arc-extinction characteristics.
