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, offering protection against overloads and short circuits. It has a 15kA breaking capacity, meaning it can safely interrupt fault currents up to 15,000 amps without being damaged. The D-50A rating indicates that the breaker trips when the current exceeds 50 amps, with the D curve providing protection for circuits with high inrush currents, such as those used by large motors, industrial equipment, or transformers.

IEC 60947-2 standard

RoHS compliant
