Product Introduction:
General GCK type low-voltage with drawable switchgear (hereinafter referred to as switchgear) is applicable to the power distribution system with AC 50(60)HZ, rated operating voltage of 660V and below. It consists of two parts, the Power Distribution Center (PC) cabinet and the Motor Control Center (MCC). As a power distribution motor control and lighting distribution equipment. The switchgear complies with IEC60439-1 (low-voltage switchgear and control equipment), GB7251.1-2013 (low-voltage switchgear and control equipment), and GB/T14048.1-2006 (low-voltage switchgear and control equipment general rules). And it has high breaking capacity, good dynamic thermal stability, advanced and reasonable structure, flexible electrical scheme, series, strong versatility, arbitrary combination of various program units, and a large number of loops accommodated by a single cabinet, saving floor space ,high degree of protection, safety and reliability, easy maintenance and so on. This product is widely used in power plants, substations,metallurgy, textile, petrochemical, factories and mines, high-rise buildings and other occasions. Standard GB7251 Low-voltage switchgear and control equipment Service environment 1.Air temperature: -35℃~+40℃ 2.Humidity: Monthly average humidity 95%; Daily average humidity 90% . 3.Altitude :≤ 2500m 4.Ambient air not apparently polluted by corrosive and flammable gas, vapor etc. 5.No frequent violent shake Features This device is a bayonet type switch device. It adopts a modular structure design. All the structural parts of the cabinet frame are galvanized, spray treated, and connected to each other as a basic cabinet frame with screws. Doors, baffles, partitions,drawers are added as required. , mounting brackets, busbars and electrical components are assembled into a complete control center cabinet. From the structure, it can be divided into three parts: cabinet, bus system and functional unit. The device is designed for two types of three-phase four-wire and three-phase five-wire power distribution system, in which PE line of protection grounding bus is installed on the underside of the cabinet, and the outlet end is connected with bus bar,which makes it very convenient for users to connect cables; In order to ensure the reliable continuity of the grounding, all the guide rails and other general parts of the cabinet are galvanized; natural ventilation mesh covers are provided on the top of the switchgear without reducing the degree of protection of the enclosure. Compact structure, can accommodate more functional units in a smaller space, saving user investment. 1. Structural versatility. The cabinet body is assembled from modular structure of C section (E=25mm), and the assembly is flexible. 2. Various sizes of draw-out units can be combined in any combination to meet system design requirements. 3. vertical busbars and outlets have good insulation protection, thus ensuring safe and reliable after-cabinet maintenance. 4. The unique mechanical locking mechanism has obvious operation, test,and extraction position marks, and the operation is safe and reliable. 5. The drawer propulsion mechanism adopts bearing rolling, the drawer operation is flexible and convenient, and the same specification drawer 6. the design of the combination of a strong prog Technical Date No. Item Unit Data 1 Rated voltage V 400,690 2 Rated insulation voltage V 660,1000 3 Rated current A 400~6300 4 Rated current of drawer accessories A 250,400,630 5 Rated short-circuit current KA 20~120 6 Insulation: Power frequency withstand voltage V Main circuit:2500; Auxiliary circuit 2000 7 Protection class IP4X 8 Operating mechanism Manual mechanism; Electric mechanism 9 Operational power supply V DC:110,220; AC:110,220 10 Overall dimension(Width*Depth*Height) mm 600(800,1000)x800(1000)x2200 11 Weight KG 300~1000 Note: For short circuit breaking and peak current is based on Fuse plus combination
