The MDmax low-voltage switchgear is divided into two series: MDmax ST and MDmax FC. It is a combined multi-function low-voltage switchgear with full type test (TTA), which conforms to GB7251.1-2005 and IEC60439-1 standards. The electrical and mechanical design uses a modular principle that combines standard components and standard components to achieve compactness, versatility and flexibility in the cabinet solution.

Working Conditions

MDmax low-voltage switchgear is an electrical device suitable for indoor installation.

Ambient temperature

Shortest time maximum temperature          +40℃

24-hour maximum average temperature  +35℃

Minimum  temperature   -5℃

The equipment should be derated when it is used above the above ambient temperature.

Environmental conditions

The climatic environment during normal work is in accordance with the relevant provisions of GB7251.1-2005 and IEC60439-1, and the relative humidity of the surrounding environment is 50% at 40 °C.

The conditions of the installation location of the switchgear should meet the requirements of the corresponding standards. In the case where condensation will occur, ventilation or heat lamp measures will be used inside the switchgear to prevent condensation. If the switchgear is installed above 2000 meters above sea level, the equipment should be derated.
