  • Product Description
  • Main Features

MNS Low-voltage extraction switchgear is mainly composed of some combined motor control units and other functional units. These units are mounted in a closed metal cabinet by overlapping the upper and lower parts. Each cabinet body is connected with a horizontal bus set above the cabinet body, and the functional units of the same cabinet body are connected with a vertical bus in parallel. The cabinet body is divided into four isolation zones: horizontal bus zone, vertical bus zone, cable zone and equipment installation zone. Functional units are installed in their respective small rooms. When any functional unit has an accident, it will not affect other units and prevent the accident from expanding

1.Anti arc design and complete type testing to ensure the safety of operators

2.2. Effectively prevent temperature rise, overvoltage, and seismic resistance, ensuring the continuous operation of equipment 

3.Multiple flexible combinations of side outlet, rear outlet, back-to-back, and other O以ions to adapt to various spaces

4.Modular design has a compact structure, saves space, is easy to upgrade and transform.and reduces design time 

5. Extractable design with better availability and interchangeability, reducing losses caused by downtime maintenance

6. Plug一 in and fixed design can provide customers with more choices, taking intc account system reliability, availability, and flexibility, to meet various working conditions and userneeds 

7. Intelligent temperature measurement technology, real-time monitoring of key component temperatures, reducing the risk of power failure
