GCK low voltage draw out switchgear
summary:
GCK low voltage draw out switchgear is suitable for AC three-phase four wire and three-phase five wire systems with a rated working voltage of 380V. It is used for power receiving, feeding, no power compensation, electric energy measurement, lighting and centralized motor control in power plants, substations, industrial and mining enterprises and high-rise buildings.
This product conforms to GB7251 low voltage switchgear and control equipment, iec439.1-1992 standard.
Purpose and characteristics:
GCK low-voltage withdrawable switchgear is composed of power distribution center (PC) cabinet and motor control center (MMC). It is suitable for power users in power plants, substations, industrial and mining enterprises and other power distribution systems with AC 50Hz, working voltage to 660V and working current to 3150A. It is used for power distribution, electric energy conversion and distribution control of motor control and lighting distribution equipment.
This series of products has the advantages of high breaking capacity, good dynamic and thermal stability, advanced and reasonable structure, practical electrical scheme, seriality, strong versatility, arbitrary combination of various scheme units, more circuits contained in one cabinet, saving floor space, beautiful appearance, high protection level, reliable operation, convenient maintenance and so on.
