Applications :
|
DZ15L series Residual Current Circuit Breakers are suitable for AC 50Hz 380V circuits with rated current up to 125A,used for protection against overload,shortcircuit and earth leakage of distribution circuits and motors,and for load control in power system, as well as for unfrequent switchover of circuit.This product adopts oil-damping electromagnetic release,so the time-current characteristics are more reliable,more steady,and hardly effected by ambient temperature,especially suitable for the areas with large temperature difference in four seasons.It shows obvious energy-saving effect because of its lower inner resistance and power loss.High interrupting capacity,residual operating time divided into rapid type and time-delay type make them to be used as stage protective switch against earth leakage in low-voltage power system.
