The GCK Low Voltage Switchgear's withdrawable design allows for flexible combinations of different functional units, integrating more power distribution, control, and protection circuits within a limited cabinet space. It is suitable for power plants, substations, industrial and mining enterprises, and industrial automation projects. The biggest difference between it and ordinary fixed low-voltage switchgear lies in its withdrawable functional unit design.
For industrial projects, low-voltage switchgear often not only distributes power but also controls numerous motors, pumps, fans, conveyors, and production line loads. If all circuits use a fixed installation structure, maintenance or replacement of a particular circuit could result in lengthy power outages and operation times.
The GCK system incorporates two major functional sections:
Used for receiving, distributing and feeding low-voltage electrical power. Incoming, bus-coupler and outgoing feeder circuits can be configured according to the project distribution scheme.
Designed for motor switching, control, protection and distribution. Typical loads include pumps, fans, compressors, conveyors and motors used in production systems.
This PC + MCC architecture allows GCK to address both power distribution and motor control requirements within an integrated low-voltage switchgear system.
An industrial MCC system may contain dozens of motor circuits, with each motor having different power ratings, starting methods and protection requirements. Withdrawable functional units allow circuits to be organized according to actual load requirements while maintaining a structured internal arrangement.
For maintenance personnel, the architecture can also reduce unnecessary interference with other circuits and allow individual functional units to be inspected, serviced or replaced more efficiently.
When evaluating a GCK Low Voltage Switchgear, purchasers should therefore look beyond cabinet dimensions and rated current and consider:

The GCK Low Voltage Switchgear boasts high breaking capacity and is designed for thermal and dynamic stability in low-voltage power distribution systems.
When a short-circuit fault occurs, the switchgear must not only consider the normal operating current but also withstand the thermal and electrodynamic effects generated during the short circuit.
Therefore, a complete electrical design is required, encompassing the cabinet structure, busbar system, insulation spacing, connection methods, and protective components.
HAGOE implements full-process control over the equipment during manufacturing, including sheet metal processing, busbar installation, component assembly, secondary wiring, and overall cabinet testing.

If the project primarily involves general low-voltage power distribution, a fixed structure like the GGD (Gas Distribution Device) is usually sufficient.
If the project includes a large number of motor circuits and places greater emphasis on circuit density, functional unit management, and ease of maintenance, the GCK (Gas Distribution Controller) Low Voltage Switchgear is generally a better choice.
The GCK is not simply an "upgraded version of the GGD"; both are better suited to different power distribution architectures.
GCK can be used for production lines, machinery, pump systems, fans and automated manufacturing equipment where centralized power distribution and motor control are required.
For water treatment facilities and pumping stations containing multiple pumps, motors and auxiliary loads, MCC functional units can be arranged according to individual motor circuits.
Mining, metallurgy and heavy-industry facilities typically contain high concentrations of motor loads. GCK can be configured for centralized distribution, motor control and protection.
GCK can support centralized low-voltage distribution and motor-control requirements in large buildings, municipal infrastructure and transportation-related projects.
GCK Low Voltage Switchgear is suitable for general industrial electrical environments:
Installation altitude: ≤2,000 meters
Ambient temperature: -5°C to +40°C
24-hour average temperature: ≤ +35°C
Relative humidity at +40°C: ≤50%
Relative humidity at +20°C: Up to 90%
Installation tilt angle: ≤5° (vertical direction)
Not suitable for locations with fire or explosion risks, severe pollution, chemical corrosion, or severe vibration.
Transportation and storage: Transport/storage conditions are -25°C to +55°C, with short-term exposure temperatures up to +70°C. If actual site conditions exceed the above limits, such as high altitude, high humidity, corrosive environments, or abnormal temperatures, specific circumstances should be specified during the procurement phase for technical evaluation and configuration.
Hagoe Electric Technology Co., Ltd. was established in 2008 and has more than 18 years of experience in power transmission, distribution systems, power electronics and new energy electrical solutions.
For complete low-voltage equipment such as GCK, manufacturing capability involves more than cabinet fabrication. It includes electrical engineering, sheet-metal processing, busbar systems, component installation, secondary wiring and complete-cabinet testing.
HAGOE operates a professional R&D team and modern manufacturing base, with registered capital of RMB 51 million and more than 34 national patents.
Manufacturing equipment includes:
These capabilities support cabinet fabrication accuracy, production consistency and quality control for complete switchgear assemblies.
GCK is mainly used for low-voltage power distribution, motor control and lighting distribution in power plants, substations, manufacturing facilities, mining, water treatment and infrastructure projects.
The maximum working voltage is 660V AC, designed for 50Hz low-voltage AC distribution systems.
The rated current can reach 3150A, with the final configuration determined by the incoming, busbar and feeder requirements.
GCK uses withdrawable functional units and incorporates an MCC motor control center, allowing motor circuits to be configured according to motor power, starting methods and protection requirements.
GGD is a fixed low-voltage distribution cabinet commonly used for conventional power distribution. GCK uses withdrawable functional units and is better suited to industrial systems requiring multiple feeders, motor-control circuits and greater maintenance flexibility.
