Hager NSN NSN Circuit Breaker, 2-Pole, 50 A, Type D, 415 V ac AC, 15 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 protect circuits from overloads and short circuits. It has a 15kA breaking capacity, meaning it can safely interrupt fault currents up to 15,000 amps without sustaining damage. The D-50A rating indicates that the breaker will trip when the current exceeds 50 amps, with the D curve providing protection for circuits with high inrush currents, such as those powering large motors, compressors, or other inductive loads.
