Product name:

MNS low-voltage withdrawable switchgear

Product introduction:

MNS low-voltage withdrawable switchgear is suitable for power systems with AC 50~60Hz and rated working voltage up to 690V; used for power generation, transmission and distribution, power distribution, power conversion and control of power consumption equipment. It is widely used in power systems, petroleum and petrochemical, industrial and mining enterprises, public utilities, municipal engineering, commercial buildings and other industries.

Product features:

1. MNS low-voltage withdrawable switchgear is our company's combination of the development trend of low-voltage complete switchgear at home and abroad. It has made improvements in component selection and cabinet structure. The cabinet frame structure used is highly flexible. Once the structure is assembled, it no longer needs maintenance. Different standard components can be installed in the cabinet to meet various usage requirements.

2. Since the entire system adopts a modular design, it meets the requirements of various components, is suitable for different working environments, and achieves the corresponding protection level.

3. Compact structure, accommodating more functional units in a smaller space

4. Cabinets can be arranged back to back

5. Economical layout of power distribution circuit

6. All components are made of well-known domestic and foreign brands, which is convenient for engineering designers to design

7. Full series standardization

8. Cabinets with corresponding protection levels can be designed according to different requirements of work and environment

9. Different types of functional units can be freely installed in one cabinet, such as fixed and withdrawable

10. Independent mechanical locking mechanism, flexible and convenient operation, no special and complex tools required

11. There are two options for side outlet and rear outlet

12. With arc protection design

13. Convenient equipment update and improvement

14. High equipment operation continuity and reliability

15. Convenient assembly, no special and complex tools required

16. Door panels, side panels, top covers, bottom panels and frames are treated with electrostatic spraying. The internal metal parts are made of aluminum-zinc plate, which has strong corrosion and oxidation resistance and higher mechanical strength than the same steel plate.

17. The top cover of the rear-outlet switch cabinet is openable, which is convenient for the installation of the main busbar on site.

Technical standards:

MNS cabinet is a design-verified withdrawable low-voltage switch cabinet, which complies with IEC 61439 and GB 7251 standards and has passed CQC voluntary certification.

Working and environmental conditions:

1. MNS low-voltage withdrawable switch cabinet is suitable for indoor installation, and the protection level of the switch cabinet under other working conditions can reach IP54.

2. Ambient temperature: maximum temperature +40℃, minimum temperature -5℃.

3. 24-hour maximum average temperature +35℃.

4. When the equipment is used in an environment and temperature higher than the above, it should be operated at a reduced capacity.

5. The working conditions of measuring, metering instruments and protective relays should comply with the manufacturer's regulations.

6. Environmental conditions: clean air. During normal operation, the relative humidity of the surrounding environment does not exceed 50% at 40°C.

7. The conditions of the installation location in the switch cabinet should meet the requirements of the relevant standards. In situations where condensation may occur, ventilation or heating measures will be used in the switch cabinet to prevent condensation.

8. Altitude: not more than 2000 meters. If the switch cabinet is installed at an altitude of more than 2000 meters, the equipment should be operated at a reduced capacity accordingly.
