Overview 

The MNS low voltage withdrawable switchgear is a modularly designed low voltage distribution device, widely used in industrial, commercial, and infrastructure fields. Its main functions are to distribute, control, and protect electrical power, ensuring the safe and reliable operation of the power system. The MNS switchgear employs advanced manufacturing processes and high-quality electrical components, offering high flexibility and scalability to meet diverse user needs.


Operating Conditions

  • The ambient air temperature is not higher than +40 ° C, not lower than -5 ° C, and the average temperature within 24 hours is not higher than +35 ° C;

  • Atmospheric conditions: The air is clean, the relative humidity is not more than 50% at the maximum temperature of +40 ° C, and a higher  relative humidity is allowed at a lower temperature, such as 90% at +20 ° C, but the temperature change should be taken into account, and  condensation may occur occasionally; The altitude does not exceed 2000m;

  • The device is suitable for transport and storage processes at the following temperatures; Within the range of -25 ° C to +55 ° C, +70 ° C can be reached in a short period of time (not more than 24h), and the device shall not suffer any irreparable damage at these limit temperatures, and shall be able to work normally under normal conditions; If the above conditions of use cannot be met, it shall be resolved by negotiation  between the user and the manufacturer.

  • When the device is used on offshore oil drilling platforms and nuclear power plants, a separate technical agreement shall be signed.


Product Features

  • Modular Design: The standardized modular design of the MNS switchgear provides high flexibility and scalability, facilitating easy installation, maintenance, and upgrades.

  • High Safety: The robust cabinet structure includes comprehensive protection measures, such as a protection rating of up to IP54, effectively preventing dust and moisture ingress and ensuring the safe operation of the equipment.

  • Reliable Electrical Performance: The use of high-quality electrical components such as circuit breakers, contactors, and relays ensures stable electrical performance and long service life.

  • Intelligent Control: The switchgear supports intelligent monitoring and management systems, enabling real-time monitoring of electrical parameters, fault diagnosis, and early warnings to enhance system operational efficiency and safety.

  • Ease of Maintenance: The drawer-type design allows each functional unit to be independently withdrawable, facilitating inspection and replacement, reducing downtime, and improving maintenance efficiency.

  • Space Saving: The compact structure occupies a small footprint, making it suitable for various installation environments and optimizing space utilization.

  • Eco-Friendly and Energy Efficient: The switchgear uses environmentally friendly materials and energy-saving designs, reducing energy consumption and environmental impact, in line with modern green environmental standards.

  • Multiple Protection Functions: It is equipped with multiple protection functions such as short-circuit protection, overload protection, and leakage protection, ensuring the safe operation of the power system.

  • Wide Applicability: The switchgear is suitable for various low voltage distribution systems, including factories, commercial buildings, data centers, and transportation facilities, offering a broad application prospect.
