The Schneider Electric Easy9 miniature circuit breaker is designed to protect electrical circuits against overloads and short circuits. Featuring four poles and a 63 A nominal current, it is suitable for 400 V three-phase installations. Its "C" tripping curve makes it appropriate for circuits with moderate inrush currents, while its 6 kA breaking capacity helps to interrupt fault currents. It is designed for DIN-rail mounting and occupies 4 modules.
