Hager NSN NSN 20 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 protect four-phase circuits from overloads and short circuits. It features a 25kA breaking capacity, meaning it can safely interrupt fault currents up to 25,000 amps without damage. The D-20A rating indicates that the breaker trips when the current exceeds 20 amps, with the D curve providing protection for circuits with high inrush currents, typically found in large motors, inductive loads, or heavy-duty machinery.
