Working and environmental conditions
MD max low-voltage switchgear is suitable for indoor installation of electrical equipment.
Environmental temperature: short time maximum temperature +40℃
24-hour maximum mean temperature +35℃
Minimum temperature -5℃
The equipment should be operated at reduced capacity when used at ambient temperatures higher than the above.
Environmental conditions: normal working climate environment according to GB7251.1-2005 and IEC60439-1 standard relevant provisions, surrounding relative humidity: 40℃ is 50%.
The conditions of the indoor installation site of the switch cabinet shall meet the requirements of the corresponding standards. In the event of condensation, ventilation or heating measures will be adopted inside the switch cabinet to prevent condensation. Such as switchgear
If the equipment is installed at an altitude of more than 2000 meters, the capacity of the equipment should be reduced accordingly.
