Hager NRN NRN Circuit Breaker, 4-Pole, 50 A, Type C, 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 four pole (4P) electrical protection device designed for four-phase circuits to protect against 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 C-50A rating means the breaker trips when the current exceeds 50 amps, with the C curve providing protection for circuits that experience moderate inrush currents, such as heavy machinery or large motors.
