GCK Indoor Low Voltage Withdrawable Swithgear
Production description :
GCK type switchgear is suitable for three-phase AC 50 /60HZ, max voltage 660V, rated current to 3150A system and three-phase four-wire and three-phase five-wire, it is widely used in power plants, substations, industrial and mining enterprises, hotels, airports, docks and the building of broadcasting and communication center, transmission & distribution and the electric energy conversion, power distribution and power consumption in PC and motor control center MCC.
Compared with the GCS cabinet, which has a maximum of 11 module small drawers and a minimum unit of 1/2, and the MNS cabinet, which has a maximum of 9 module small drawers and a minimum unit of 1/4, the GCK can achieve a maximum of 9 modules and a minimum unit of 1.However, no matter GCS,MNS or GCK, there are three station states: separation, test, and connection
This series of products with high breaking capacity, good dynamic stability, advanced and reasonable structure, electrical program of practical, series, strong versatility, various schemes of unit combination, a cabinet contained many circuits, save the area, beautiful appearance, high-level protection, safe and reliable, convenient maintenance, etc.
It accords with the standards IEC439 NEMA ICS2-322 as well as the GB7251-87 "Low voltage complete switch device " national standards and ZBK36001-89 "low voltage withdraw type complete switch device" professional standards"
