Hager NSN NSN Circuit Breaker, 3-Pole, 10 A, Type D, 415 V ac AC, 25 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 three pole (3P) electrical protection device designed for three-phase circuits to safeguard against overloads and short circuits. It has a 25kA breaking capacity, meaning it can safely interrupt fault currents up to 25,000 amps without sustaining damage. The D-10A rating indicates that the breaker trips when the current exceeds 10 amps, with the D curve providing protection for circuits that experience high inrush currents, such as those used by large motors, transformers, or other heavy-duty equipment.
