Factory price d curve breaker in France

What is a D-curve breaker?

D-curve breakers are suitable for circuits with high inrush currents, such as motors. They handle 10–20 times the nominal current. D-curve breakers are more sensitive to tripping than B- and C-curve breakers, making them unsuitable for circuits with low inrush currents.

What is a D-trip circuit breaker?

Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit. D-trip circuit breakers prevent nuisance tripping, so they are best for equipment that has a high spike in current at startup, such as transformers, power supplies, and heaters.

What is a C-curve breaker?

C-curve breakers are commonly used to protect circuits with devices that have a relatively low inrush current, such as lighting, outlets, household appliances, and small machinery. These breakers handle 5–10 times the nominal current and react slower to overloads and short circuits compared to B-curve breakers, as their tripping current is higher.

What does a circuit breaker do?

A circuit breaker, also known as an automatic fuse, is a crucial component of electrical panels. It protects circuits and users by detecting the flow of electricity and shutting it off when the current exceeds the allowable threshold. Circuit breakers quickly react to overload situations, preventing equipment damage and reducing fire risks.
