1、 Product model and meaning
GCK: G is a closed switchgear, C is a pull-out switchgear, and K is a control center

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 working voltage less than or equal to 660V, rated current 4000A and below, as power distribution, motor control, lighting and other distribution equipment.
GCK switchgear complies with IEC60439-1 "Low voltage switchgear and control gear" and GB7251.1-1997 "Low voltage switchgear and control gear" GB/T14048.1-93

Standards such as "General Principles for Low Voltage Switchgear and Control Equipment". And it has high breaking capacity, good dynamic and thermal stability, advanced and reasonable structure, flexible electrical scheme, series and strong universality, various scheme units can be combined arbitrarily, and one cabinet.

It has the advantages of accommodating a large number of circuits, saving floor space, high protection level, safety and reliability, and easy maintenance.
Structural Features
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 MCC cabinet drawer compartment 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 drawers of the power switch, contact switch, and MCC cabinet have three positions: on position, test position, and off position.
