Hager NSN NSN 25 A Automatsäkring, 4 polen Typ D karaktäristik 415 V ac, brytförmåga 25 kA

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 to safeguard four-phase circuits from overloads and short circuits. It has a 25kA breaking capacity, meaning it can safely interrupt fault currents up to 25,000 amps without damage. The D-25A rating means the breaker will trip when the current exceeds 25 amps, with the D curve offering protection for circuits that experience high inrush currents, commonly found in large motors, transformers, and other inductive loads.
