Standards and specifications
  • IEC60493 Low-voltage switchgear and control gear combination
  • GB7251.1-2005 Low-voltage switchgear assembly and control the first part
  • Q/HD. J5 090-2007 Enterprise standard of MNS series low-voltage switchgear
  • ZBK36001— 89 Low-voltage withdrawable switchgear

Working conditions

  • Ambient air temperature is between +40ºC and -5ºC, while, average temperature in 24h is no more than +35ºC.
  • Atmospheric Conditions: Clean air, relative humidity is no more than 50% at the highest temperature +40º C, relative higher humidity is admissible at lower temperature, for example, it is 90% at +20º C. Should consider the change of temperature, there is moderate dewing in accident.
  • Altitude is no more than 2000m.
  • Pollute grade is 3.
  • The equipment is applied to transportation and storage process at the below temperature: Between
  • -25ºC and +55ºC. It can up to be +70ºC in short time (no more than 24h). At the extreme temperature, it should not be subject to unrecoverable damage. Meanwhile, it should run well at normal condition.
  • If the above application conditions can not be met, the user should confer with the manufacturer to solve it.

Applications

MNS type low-voltage switchgear (short as equipment) is a modularized and multifunctional low-voltage distribution cabinet. It is applied in the field of petroleum, chemical industry, metallurgical industry, industrial and mining enterprises and infrastructure which need high reliability low voltage system and distributing and motor control system. MNS is whole series low-voltage switchgear and can meet full range requirement. In the low voltage system of below 5000A, MNS can provide high standard reliability and safety. The special profile structure and connection manner and compatibility to various components can meet the requirement of harsh period and power supply continuity.
