Applications :
DZ15 series Moulded Case Circuit Breakers are suitable for AC 50Hz 380V circuit with rated current up to 125A,used for protection against overload,short-circuit of distribution circuit and motors, and for load control in power system, as well as for unfrequent switchover of circuits.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 1OkA makes G type MCCB to be used in more wide scope. |
