Summary
MNS is a modular, multi-functional low-voltage distribution cabinet. It is applied to all low-voltage systems that need high reliability in metallurgy, petroleum, chemical industry, industrial and mining enterprises, infrastructure and other fields: power distribution and motor control system.
The cabinet structure adopted by MNS has high flexibility. According to your needs or different use occasions, multiple models and specifications of components can be installed in the cabinet; according to different electrical equipment, multiple types of feeder units can be installed in the same cabinet or the same cabinet. For example: the feed circuit and the motor control circuit can be mixed together.
MNS is a full range of low-voltage switchgear, which can meet your all-round needs. It is applicable to all low-voltage systems below 4000A.
MNS can provide a high level of reliability and safety. The humanized design strengthens the protection for personal and equipment safety.
MNS is a fully assembled structure. Its unique profile structure, connection mode and compatibility with various components can meet the requirements of demanding construction period and power supply continuity.
Executive Standards: lec60439, gb7251.1.

Normal use environmental conditions
1. The ambient air temperature is not higher than + 40 ℃, not lower than - 5 ℃, and the average temperature within 24 hours is not higher than + 35 ℃;
2. The relative humidity of the surrounding air shall not exceed 50% when the maximum temperature is + 40 ℃, and there is a large relative humidity when the temperature is lower, and the change may occasionally produce moderate condensation;
3. For indoor use, the altitude of the place of use shall not exceed 2000m;
4. It shall be installed in the place without severe vibration and impact and without corrosion of electrical components.

Main circuit scheme
There are 23 groups of main circuit schemes and 44 specifications in the switchgear, but the derived schemes and specifications due to the change of auxiliary circuit control and protection are not included.
