Frequently asked questions
What is the difference between B and C curve circuit breakers?
A B-curve breaker trips between 3-5 times its rated current, making it suitable for resistive loads and low inrush currents. A C-curve breaker trips between 5-10 times its rated current, making it better for inductive loads like motors that have higher inrush currents.
