GCK Low-voltage extraction switchgear is mainly composed of some combined motor control units and other functional units. These unns are mounted in a closed metal cabinet by overlapping the upper and Iower parts. Each cabinet body is connected with a horizontal bus set above the cabinet body, and the functional units of the same cabinet body are connected with a vertical bus in parallel. The cabinet body is divided into four isolation zones: horizontal bus zone, verticI bus zone,cable zone and equipment installation zone. Functional units are installed in their respective small rooms. When any functional unit has an accident, it will not affect other units and prevent the accident from expanding.
This product meets the JB/T9661-1999 standard. This product adopts IP40 protection level stipulated by IEC114. When all doors and guards are closed, or when doors are opened and functional units are moved out, it can reach corresponding protection level, which can ensure personal safety. The product is equipped with prefect and reliable grounding system and protection circuit. All functional units can break short-circutt current according to the specified performance requirements. The input unit has three-stage protection characteristics Therefore, the reliabilrty of power supply and the safety of equipment and system can be guaranteed. All functional units can be connected with PC wiring board (programmable logic controller) or microprocessor through interface. As the executive unit of automatic control system, other functional units and functional combinations can be provided according to user's needs. This product is suitable for 380V AC circuit with 50Hz frequency.
