3. Key Features

The GCS switchgear provides enhanced reliability, safety, and flexibility, making it ideal for demanding industrial power distribution systems.

3.1 Optimized Thermal Performance

 Efficient heat dissipation through optimized busbar layout, reducing temperature rise on connectors, terminals, and cable heads.

3.2 Independent Compartmentalization

 Functional units are physically separated, ensuring that faults in one unit do not affect other components, improving system reliability.

3.3 Superior Short-Circuit Withstand Capacity

 The horizontal busbar design enhances dynamic thermal stability, allowing the switchgear to withstand short-circuit impacts up to 176kA.

3.4 Modular and Scalable Design

 Each MCC (Motor Control Center) cabinet can accommodate up to 22 independent circuits, supporting large-scale industrial operations.

3.5 Flexible Cable Entry Options

 Supports top, bottom, front, or rear cable entry, making installation and maintenance more convenient.

3.6 Advanced Fault Protection System

 Equipped with current-limiting reactors that stabilize bus voltage and mitigate short-circuit current surges, improving overall system protection.

3.7 High-Density Withdrawable Units
