When comparing the C curve and D curve MCBs (Miniature Circuit Breakers), the key difference lies in their tripping characteristics:C Curve MCB: This type trips when the current exceeds 5 to 10 times the rated load. It is commonly used in commercial and light industrial applications where high inrush currents are less frequent, such as for fluorescent lighting or general power points.D Curve MCB: This type trips when the current exceeds 10 to 20 times the rated load. It is designed for industrial or commercial applications with high inrush currents, like transformers, X-ray machines, and heavy electric motors.
