Hager NSN NSN Circuit Breaker, 4-Pole, 16 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 four pole (4P) electrical protection device designed for four-phase circuits to prevent overloads and short circuits. It features a 25kA breaking capacity, allowing it to safely interrupt fault currents up to 25,000 amps without being damaged. The D-16A rating indicates that the breaker will trip when the current exceeds 16 amps, with the D curve offering protection for circuits with high inrush currents, such as large motors, transformers, or industrial equipment.
