Havells MCB FP D Curve

MCB FP D Curve is a four-pole miniature circuit breaker designed for three-phase electrical systems with a neutral wire. The "D" curve indicates that the breaker trips when the current exceeds 10 to 20 times the rated current, making it suitable for circuits with high inrush currents, such as transformers or heavy machinery. It provides protection against overloads and short circuits, ensuring the safety and reliability of industrial and commercial electrical systems. This type of MCB is often used in systems with large electrical loads or equipment that experience brief current surges.
