Air pump distribution cabinet, also known as motor control center (MCC), is a low-voltage distribution device that assembles switchgear, measuring instruments, protective appliances, and auxiliary equipment in enclosed or semi enclosed metal cabinets or screens.
The air pump distribution cabinet mainly consists of complete sets of components (such as the distribution box shell and related accessories), electrical components (such as circuit breakers, residual current switches, etc.), and related accessories.
Advantages And Characteristics:
- The clear separation between functional units and compartments can effectively prevent the spread of faults, limit the impact of faults to small areas, and improve the reliability and stability of the system.
- The use of flat arranged busbars enhances the dynamic and thermal stability of the switchgear, allowing it to withstand large short-circuit current surges, such as 80/176kA short-circuit current surges, ensuring the safe operation of the power system in the event of short-circuit faults.
- The cabinet structure is compact and occupies a small area, which can effectively save space in the distribution room. It has great advantages for places with limited space, such as commercial buildings in urban centers and underground substations.
- The number of circuits in a single MCC cabinet can reach up to 22, fully considering the needs of automated electric door (machine) groups in industries such as large single machine capacity power plants and petrochemical systems. It can meet the power distribution needs of a large number of equipment in complex systems, reduce the number of distribution cabinets used, and save space and costs.
- Adopting high-quality copper bars and advanced busbar design, low resistance reduces energy loss during transmission, improves energy utilization efficiency, and meets the requirements of modern society for energy conservation and consumption reduction.

Application area:
- In the field of industrial manufacturing, air pump distribution cabinets serve as power control centers in automated production lines, machine tool equipment, pharmaceutical equipment, and metallurgical equipment, providing stable power supply and precise power control for various mechanical equipment.
- In the field of transportation, industries such as rail transit, ships, airports, highways, and bridges that require a large amount of power supply and control, as well as electric vehicle charging stations, all require distribution cabinets as power control and distribution centers.
- In the field of agriculture, distribution cabinets can achieve power control and distribution in large-scale agricultural machinery and greenhouse equipment, meeting the electricity demand in agricultural production.
- In the automotive field, testing of automotive braking systems requires the use of a high-pressure air pump in conjunction with a distribution cabinet to provide the necessary air pressure for testing.
