MNS low voltage withdrawable switch cabinet

Structural features

a.Compact design: It adopts a pull-out structure with high space utilization, and can integrate multiple functional units in a limited space.

b.Modular and flexible assembly: Based on 25mm C-profile, it can meet different structural requirements and can be freely combined into standard units such as protection, operation, conversion, control, adjustment, measurement and indication. It provides more than 200 parts and supports diversified frame and drawer configuration.

c.High safety: High-strength flame-retardant engineering plastic components are used in key parts to significantly improve protection performance.

d.Advanced technical indicators: core parameters meet international technical standards and have excellent performance.

Environmental conditions for use

(1)Ambient temperature requirements

The equipment operating environment temperature range is -5℃ to +40℃, and the average temperature within 24 hours shall not exceed +35℃.

(2)Humidity and air quality requirements

The working environment should maintain clean air and be free of corrosive gases, conductive dust or flammable and explosive substances.

Relative humidity limit: When the ambient temperature is +40℃, the humidity shall not exceed 50%; at lower temperatures (such as +20℃), the humidity is allowed to rise to 90%, but attention should be paid to temporary condensation that may be caused by temperature fluctuations.

(3)Altitude restrictions

The altitude of the equipment installation site should not exceed 2000 meters. When the altitude exceeds this level, the effect of thin air on heat dissipation and insulation performance must be considered.

(4)Transportation and storage conditions

Temperature range: The equipment can adapt to an environment of -25°C to +55°C during transportation and storage;

Short-time limit: It is allowed to withstand a high temperature of +70℃ for a short period of time not exceeding 24 hours;

Performance requirements: Under the above extreme conditions, the equipment must not suffer permanent damage and should be able to maintain standard working conditions after returning to normal environment.

(5)Special working condition handling

If the actual use environment exceeds the above specified range (such as extreme cold, high humidity, ultra-high altitude, etc.), the user needs to negotiate with the manufacturer to customize a solution to ensure reliable operation of the equipment.
