The GCK low-voltage withdrawable switchgear (hereinafter referred to as the switchgear) consists of two parts: the power distribution center (PC) cabinet and the motor control center (MCC). This device is suitable for control and distribution systems with AC 50 (60) Hz, rated operating voltage of 660V and below, and rated current of 4000A and below. It is used as power distribution, motor control, and lighting distribution equipment.

       And it has the advantages of high breaking capacity, good dynamic and thermal stability, advanced and reasonable structure, flexible electrical scheme, series, strong universality, arbitrary combination of various scheme units, a large number of circuits accommodated in one cabinet, saving floor space, high protection level, safety and reliability, and convenient maintenance.

1.The whole cabinet adopts an assembled combination structure, with modular hole installation, strong universality of components, good applicability, and high standardization.

2.The upper part of the cabinet is the busbar room, the front part is the electrical room, and the rear part is the cable inlet and outlet room. There are steel plates or insulation boards between each room for isolation to ensure safety.

3.The door of the drawer compartment in the MCC cabinet is mechanically interlocked with the operating handle of the circuit breaker or isolation switch, and the door can only be opened when the handle is in the open position.

4.The power switch, contact switch, and drawer of the MCC cabinet have three positions: on position, test position, and off position.

5.The top of the switchgear can be equipped with a busbar bridge according to the power supply needs.
