In a large – scale industrial machinery manufacturing plant, GE CK11CE300 has been playing a crucial role. For instance, in the production line of heavy – duty machine tools, the CK11CE300 is used to control the high – power motors that drive the cutting tools. The high – power motors in these machine tools often require a large – current on – off control. The CK11CE300, with its high – current – carrying capacity (rated current of 450A), can handle the large inrush current when the motors start up smoothly. It ensures stable operation of the motors during different machining processes such as roughing and finishing, which is essential for maintaining the accuracy and efficiency of the machine tools. In addition, the 3 – pole main contact configuration of the CK11CE300 is well – suited for the three – phase power supply system of the machine tools, enabling reliable power distribution and control.

In a power generation and distribution substation, GE CK11CE300 is applied in the control circuit of power transformers. When the power grid needs to adjust the power distribution, the CK11CE300 is used to control the on – off of the feeder circuits connected to the transformers. For example, during peak – load periods, additional feeder circuits may need to be connected to meet the increased power demand. The CK11CE300 can quickly and accurately close the contacts to connect the new feeder circuits, ensuring a stable power supply. Its high – voltage insulation performance (insulation voltage of 1000V) makes it suitable for use in high – voltage substation environments, protecting against electrical breakdown and ensuring the safety and reliability of the power distribution system.

In large commercial buildings, the HVAC (Heating, Ventilation, and Air – Conditioning) systems are energy – intensive. GE CK11CE300 is used in the control of large – capacity air – handling units and chillers. For a large shopping mall with a vast area to be air – conditioned, the air – handling units require high – power motors to circulate air. The CK11CE300 controls the starting and stopping of these motors, and its ability to withstand frequent on – off operations (mechanical life of 10000 times) is crucial. In addition, in the chiller system, which is responsible for cooling the refrigerant, the CK11CE300 controls the power supply to the compressor motors. The accurate control provided by the CK11CE300 helps to optimize the energy consumption of the HVAC system, ensuring a comfortable indoor environment while reducing operating costs.

On large – scale cargo ships, GE CK11CE300 is integrated into the ship’s power distribution and control systems. For example, it is used to control the motors of the ship’s propulsion system auxiliary equipment, such as the cooling water pumps and lubrication oil pumps. These pumps need to operate stably during the ship’s voyage to ensure the normal operation of the propulsion system. The CK11CE300’s resistance to vibration and harsh marine environments makes it reliable for use on ships. Its compact design (with an appropriate size considering the space – limited shipboard environment) also allows for easy installation in the ship’s electrical control cabinets.
