This device is applicable to three-phase alternating current with a frequency of 50Hz, a rated working voltage of 660V, and a maximum rated current of up to 6300A. The enclosure protection level can reach IP40. As a control device for various power generation, transmission, distribution, power conversion and power consumption equipment, it can be widely applied in low-voltage power distribution systems of power systems, petrochemical industries, industrial and mining enterprises, public utilities, municipal engineering, commercial buildings, etc. Except for general land use, after special treatment, it can also be used in offshore oil drilling platforms and nuclear power plants. 

Structure Explanation

Compact design: With a smaller space, it can accommodate more functional units. 

The structure has strong versatility and flexible assembly: The C-shaped profiles with a 25mm modulus can meet the requirements of various structural types, protection levels, and usage environments. 

Adopting standard module design: It can be separately composed into standard units such as protection, operation, conversion, control, regulation, measurement, indication, etc. Users can freely select and assemble them according to their needs. With over 200 types of parts, different cabinet structure and drawer units can be formed. 

High safety: A large number of high-strength flame-retardant engineering plastic components are used, effectively enhancing the safety performance of protection. 

High technical performance: The main parameters have reached the advanced domestic level. 

Main features

The MNS type low-voltage withdrawable switch cabinet body is made of 2.5mm thick cold-rolled steel plates that are bent and then processed and assembled into a C-shaped frame structure. It features high mechanical strength and good cabinet versatility. 

Adopting standard module design: It can be combined to form standard units such as protection, operation, conversion, control, regulation, measurement, and indication. 

The cabinet frame is of a modular assembly structure. The dimensions of the components inside the device and the size of the compartments are designed in accordance with modular principles. 

High safety: The product drawer assembly components extensively utilize high-strength flame-retardant engineering plastic components, enhancing the safety performance. The drawers are marked with distinct positions such as closing, opening, testing, pulling out, and isolation. The reliable mechanical interlock ensures the safety during the conversion of the drawer position.
