I.Scope of Application
DZ47-125(NC)125A series high current MCB is applied to illumination and power distribution system, to provide protection against short-circuit and overload. It is characterized by pleasing outlook, light weight, reliable performance, high breaking capacity, fast tripping and din-rail mounted method. Its housing and other components are made of high inflammable resistance and impact resistance plastics for long service life. It is mainly used in lines of AC 50/60Hz, rated voltage of single pole up to 230A, two, three or four poles up to 400V, rated current 50A~125A for overload or short circuit protection. It can also be used for infrequent switchover of illumination circuit and electric appliances under normal condition. It can be assembled with other accessories. Like under-voltage tripping device or shunt release. This switch could also used as disconnection switch to provide under-voltage protection or remote disconnection for lines.
DZ47-125 complies with Standard IEC60947-2,GB14048.2 & GB10963.
