Frequently asked questions
What is the difference between B, C, and D curve circuit breakers?
Circuit breaker tripping curves indicate how quickly they will trip under different current conditions. A C-curve breaker trips between 5-10 times its rated current, suitable for inductive loads with moderate inrush. B-curves trip at lower multiples (3-5x) for sensitive loads, while D-curves (10-20x) are for high inrush loads like large motors.
