Hager Hager NSN Circuit Breaker, 2P, 40A Curve D, 415V AC, 20 kA Breaking Capacity

The Hager Miniature circuit breakers protect and control the circuits against overloads and short circuits. They also allow to isolate circuits. The circuit breaker is a dual pole (2P) electrical protection device designed to safeguard circuits from overloads and short circuits. It has a 20kA breaking capacity, meaning it can safely interrupt fault currents up to 20,000 amps without being damaged. The D-40A rating indicates that the breaker trips when the current exceeds 40 amps, with the D curve providing protection for circuits that experience higher inrush currents, such as those with large inductive loads like motors or transformers.
