The main structure is made of C-shaped steel and adopts a standard modular design with a module of 25mm. It has strong structural versatility and flexible and convenient internal assembly;
Compact structural design, accommodating a large number of functional units in a small space; Fully consider the heat dissipation during operation when designing the cabinet. The cabinet is equipped with different numbers of heat dissipation slots on both
The various functional rooms of the device are isolated from each other, and their compartments are divided into functional unit rooms, busbar rooms, and cable rooms. The functions of each room are relatively independent;
The top cover of the cabinet can be removed when needed to facilitate the assembly and adjustment of the main busbar on site. The four corners of the cabinet top are equipped with lifting rings for lifting and shipping;
Equipped with locking function, automatic switching function, and maintenance status function; Supports multiple operating modes (optional):
Communication function: The system can be equipped with RS485 or RS232 communication interfaces and supports MODBUS communication protocol (optional);
Equipped with intelligent monitoring function (optional).
Product Description：
The MNS type low-voltage withdrawable switchgear adopts a standard modular design for the cabinet body, with a compact structure composed of reinforced C-profile assembly. The cabinet frame and all internal components are processed with aluminum zinc plate, which has strong anti-corrosion ability. All functional units are interchangeable, improving power supply reliability.
The MNS type low-voltage withdrawable switchgear is suitable for power plants, substations, petrochemicals, metallurgical steel rolling, light industry and textiles, as well as residential areas, high-rise buildings and other places. It is used as a distribution equipment for AC 50-60Hz, rated working voltage 400V power systems for energy conversion, distribution and control.
Application field：
The MNS type low-voltage withdrawable switchgear is suitable for low-voltage power supply systems with AC 50Hz, rated working voltage of 400V, insulation voltage of 690V, and rated current of 6300A and below. Widely used in power plants, substations, industrial and mining enterprises, airports, docks, petroleum, chemical, metallurgical, textile, high-rise buildings and other industries for power generation, transmission and distribution, energy conversion and control.
