MNS Draw-out Distribution Cabinet

The MNS Draw-out Distribution Cabinet is a high-end low-voltage pull-out switchgear that has been comprehensively improved and developed based on domestic excellent low-voltage switch cabinets. It is also the current top-level low-voltage complete distribution equipment in China. Compared with ordinary pull-out switch cabinets, this product adopts 1/4 modular miniature drawer units, which have a smaller volume than GCS drawers and can accommodate more units. The protection level reaches IP54. Its core positioning is to meet the extremely high requirements for power distribution reliability and safety in high-end scenarios. Even in scenarios such as nuclear power plants and semiconductor factories where no faults are allowed, it can also perform perfectly. It is a necessary equipment for top-level power distribution scenarios and is suitable for various industrial and civilian scenarios with strict requirements for power distribution safety and stability.

Technical Specifications

What are the product advantages?

Micro drawer design, more circuits and more space-saving: The MNS Draw-out Distribution Cabinet uses 1/4 modular micro drawer units. A single cabinet can accommodate up to 36 independent small circuits, which is twice the number of circuits compared to ordinary GCS cabinets. Without expanding the distribution room area, it can meet the high-end distribution requirements for multiple circuits and low loads, significantly saving floor space and reducing the cost of the site.

IP54 ultra-high protection, suitable for complex environments: The protection level reaches IP54, far exceeding the IP30 level of ordinary pull-out switch cabinets. The fully sealed structure combined with precise sealing design can effectively prevent dust and moisture from invading. Even in a high-humidity and high-dust complex environment, it can ensure the stable operation of internal components and avoid equipment failures caused by environmental factors.

Dual interlock design, ultimate safety and anti-misoperation: Equipped with mechanical interlock + electrical interlock dual protection, it can completely prevent misoperations such as pulling the drawer while carrying a load or accidentally touching live parts. It not only ensures the personal safety of operators but also avoids power outages and equipment failures caused by misoperations. It builds a comprehensive distribution safety defense line and complies with the safety standards of high-end scenarios.

Power-off maintenance without power outage: Each drawer unit is independently designed. When a certain circuit fails, only the corresponding drawer needs to be pulled out for maintenance, and other circuits will not be affected. There is no need to stop the entire distribution system, perfectly adapting to those high-end scenarios that cannot tolerate any power outage for a second, ensuring continuous and stable production and operation, and reducing downtime losses.

Advanced craftsmanship and details, stable operation with large current: Built-in large-sized thick copper busbars, with high current capacity and adequate insulation protection, can adapt to large current operations ranging from 630A to 6300A. The temperature rise is low, and the stability is strong. Combined with details such as full sealing protection and dual interlock, it ensures the long-term stable operation of the equipment without frequent maintenance.

What are the application scenarios?

With its extremely high reliability, safety and adaptability, the MNS Draw-out Distribution Cabinet is widely used in various high-end scenarios that have strict requirements for power distribution and cannot tolerate any failures.
